The present invention pertains to the area of diagnosis. More precisely, the invention concerns a method for the molecular identification of bacteria of genus Streptococcusand related genera Enterococcus, Gemella, Abiotrophia and Granulicatella using detection and/or amplifying and sequencing techniques with probes or oligonucleotide primers applied to strains of these bacterial genera.

Bacteria of the Streptococcus genus and of four related genera: Enterococcus, Gemella, Abiotrophia and Granulicatella, are Gram-positive and catalase-negative spherical bacteria of which more than around forty species are presently known. Bacteria of the genus Lactococcus, previously classified among the streptococci as Group N Streptococcus, do not come within the scope of this invention on account of their rare occurrence in human pathology, and because they can be easily distinguishedfrom streptococci through their growth at +10.degree. C. Genus Streptococcus officially comprises 55 species. Genus Gemella comprises 6 species, genus Abiotrophia comprises 1 species, genus Granulicatella comprises 3 species, and genus Enterococcuscomprises 24 species [www.springer-ny.com/bergeysoutline/main.htm]. These species are easily and frequently cultured from environmental samples, veterinary clinical specimens and human clinical specimens [Ruoff Kl. (1999) in Manual of ClinicalMicrobiology, pp. 283-296, ASM Press]. In man, different species of the Streptococcus genus are responsible for community infections which may be severe due to the invasive nature of the streptococci under consideration or through the production ofpossibly serious toxins with clinical signs distant from the site of infection. For example, Streptococcus pyogenes (Group A Streptococcus) is responsible for throat infections and post-streptococcal syndromes including rheumatic fever during whichdamage to the heart valves through an inflammatory process is responsible for possibly fatal heart valve disease. Also, several species of genus Streptococcus, in particular Group A, Group C and Group C Streptococci are responsible for life-threateninginvasive infections, myositis in particular, i.e. degenerative changes to skin, subcutaneous and muscle tissue as has been described for some years. Also, Streptococcus pneumoniae(pneumococcus) for example causes pneumonia, meningitis and septicaemia. Bacteria of the genera Streptococcus, Enterococcus, Gemella, Abiotrophia and Granulicatella can cause endocarditis i.e. infection of the heart valves in man, which come under life-threatening infectious diseases [Casalta J P et al., Journal ClinicalMicrobiology, 2002, 40: 1845-1847]. Also, some species of the genera under consideration can cause nosocomial infections, for example group A Streptococcus bacteria are responsible for bacteraemia subsequent to digestive endoscopy investigation. Inaddition, bacteria of the genus Enterococcus can cause nosocomial urinary infections after prophylactic antibiotic therapy with cephalosporins against which they are naturally resistant. These bacterial species also raise the problem of their increasingresistance to antibiotics, the resistance of Streptococcus pneumoniae to penicillin G [Garav J. Lancet Infect. Dis. 2002, 2: 404-415] and the resistance of Enterococcus spp. to vancomycin [Gold H. S., Clin. Infect. Dis. 2001, 33: 210-219; Bonten M.J. et al. Lancet Infect. Dis. 2001, 1: 314-325].

These different bacterial species raise the problem of their detection in human pathological specimens and of their identification when isolated from such samples. Conventional detection methods rely on the evidencing of Gram-positive cocciformbacteria on direct examination of the pathological specimen. It is known, however, that this microscopic detection of bacteria of the genus Streptococcus and related genera in clinical specimens has a sensitivity threshold of 10.sup.4 CFU/ml. It istherefore fully possible that a pathological specimen in man or animal contains one of the species under consideration which is not detected by direct microscopic examination of this pathological specimen. In addition, even though their structure is ofGram-positive bacterial type, they may give a false Gram-negative result after Gram staining of the pathological sample and give rise to erroneous or inconclusive identification. This is particularly frequent in bacteria of genus Gemella. In man, thisis especially the case in anatomopathological and bacteriological investigation of the heart valves when diagnosing endocarditis.

When a bacterium of one of the species of the genera under consideration is isolated in the laboratory, conventional phenotype identification methods are the most commonly used to identify bacteria of species belonging to genus Streptococcus andrelated genera, and several identification kits and automated analysers have been developed to assist phenotype identification of bacteria of genus Streptococcus and related genera. In this respect, the extent of identification in routine practice isvariable. In particular, one of the tests used for identifying Streptococci and bacteria of related genera is the detection of a haemolytic reaction, i.e. the destruction by the bacterium of red blood cells contained in a blood agar. However, thishaemolytic reaction can be inhibited by the presence of oxygen or by the presence of a peroxide when Streptococci bacteria are cultured in the presence of a high carbon dioxide concentration. Moreover, it is recognized that there exists a certain extentof subjectivity in assessing haemolysis by colonies of Streptococci and hence inter-operator variability which is detrimental to the quality of identification of these bacteria. For alpha-haemolytic streptococci, a second test is the optochinsensitivity test which enables identification of Streptococcus pneumoniae which is sensitive to this compound. However, strains of Streptococcus pneumoniae resistant to optochin have been reported [Lund E. Acta Patho. Microbiol. Immunol. Scand. 1959, 47, 308-315]. A final phenotype test is serotyping, which may also give false positive results in particular for streptococci in serogroup D on account of cross antigenicity between group D streptococci, Enterococcus and Pediococcus.

Several molecular systems have been developed to identify some serogroups or some species of genus Streptococcus, in particular for group A streptococci (Streptococcus pyogenes, Streptococcus aginosus, Streptococcus constellatus, Streptococcusintermedius) and group B (Streptococcus agalactiae) [Daly J. A. et al. J. Clin. Microbiol. 1991, 29:80-82; Heelan J. S. et al., Diagn. Microbiol. Infect. Dis. 1996, 24: 65-69] and for Streptococcus pneumoniae [Denys G. A. & Carrey R. B., J. Clin.Microbiol. 1992, 30: 2725-2727] by hybridisation of specific probes targeting the gene encoding the 16S ribosomal RNA. Also, different systems based on PCR amplification of genes coding for toxins or virulence factors have been developed todiscriminate Streptococcus pneumoniae from among .alpha.-haemolytic Streptococci [Salo P. et al., J. Infect. Dis. 1995, 171: 479-482; Morrisson K. et al. J. Clin. Microbiol. 2000, 38, 434-437; Kaijalainen T. et al. J. Microbiol. Meth. 2002, 51:111-118], and for the detection of Streptococcus agalactiae [Mawn J. A. et al. J. Clin. Pathol. 1993, 46: 633-636]. These different systems, however, only allow the identification of one or of a few species of genus Streptococcus.

An identification system for three species of streptococcus has been developed, based on amplification of the 16S-23S spacer [Forstman P. et al. Microbiology, 1997, 143, 3491-3500] but in this work identification was limited to only a few speciesof animal interest: Streptococcus agalactiae, Streptococcus dysgalactiae and Streptococcus uberis. Also, at the present time it is essential for laboratories to have 2 separate molecular targets for the detection and identification of streptococci toovercome the risks of molecular contamination inherent in the use of a single target.

Finally, no detection and identification system for Streptococcus-related genera has been developed, and more particularly for bacteria of the genera Enterococcus, Gemella, Abiotrophia and Granulicatella.

The inventors have shown in the present invention that the rpoB gene forms a genetic marker which can be used for the detection and specific identification of the bacterium of each species in genus Streptococcus and in 4 related genera:Enterococcus, Gemella, Abiotrophia and Granulicatella.

Although this gene has previously been shown to have use as a tool in bacterial identification of different bacterial genera, no publication mentions its use for identifying bacteria of genus Streptococcus and the four related genera, and theadvantage of this gene's sequence for the identification of the said bacteria has in no way been suggested. On the contrary, a few partial sequences of the rpoB gene in a few species, available in GenBank, showed slight heterogeneity placing in doubtthe advantage of this gene as an identification tool for these bacteria. Finally, the inventors have developed a tool for the simultaneous identification of four bacterial genera, requiring the development of degenerate primers which could not bededuced from any of the rpoB sequences determined for each species.

More particularly, the present invention concerns nucleic acid sequences specific to the genus or to each species of genus Streptococcus and related genera whose nucleotide sequence is derived from the rpoB gene of the said bacteria.

According to Lazcano et al. [J. Mol. Evol. (1988) 27: 365-376] the polymerase RNAs are divided into two groups as per their origin, one consisting of the RNA- or DNA-dependent viral polymerase RNAs and the other consisting of the DNA-dependentpolymerase RNAs of eukaryote or prokaryote origin (archaebacteria and eubacteria). The eubacterial DNA-dependent polymerase RNAs are characterized by a simple, conserved multimeric constitution denoted "core enzyme" represented by .alpha..beta..beta.',or "holoenzyme" represented by .alpha..beta..beta.'.sigma. [Yura and Ishihama, Ann. Rev. Genet. (1979) 13: 59-57].

Numerous studies have evidenced the functional role, within the multimeric enzymatic complex, of the .beta. subunit of the eubacterial polymerase RNA. Archaebacterial and eukaryote polymerase RNAs have a more complex structure possibly reachingten and even thirty subunits [Puhlet et al. Proc. Natl. Acad. Sci. USA (1989) 86: 4569-4573].

The genes encoding the different .alpha..beta..beta.'.sigma. (subunits of the DNA-dependent polymerase RNA in eubacteria, the genes rpoA, rpoB, rpoC and rpoD respectively, are classified in different groups comprising the genes coding forconstituent proteins of the ribosomal subunits or for enzymes involved in the replication and repair of the genome [Yura and Yshihma, Ann. Rev. Genet. (1979) 13: 59-97]. Some authors have shown that the sequences of the rpoB and rpoC genes could beused to construct phylogenetic trees [Rowland et al. Biochem. Soc. Trans. (1992) 21:40S] enabling separation of the different branches and sub-branches among the kingdoms of the living.

Before setting forth the invention in more detail, different terms used in the description and claims are defined below: By "nucleic acid extracted from bacteria" is meant either the total nucleic acid, or the genomic DNA, or the messenger RNAs,or the DNA obtained from reverse transcription of the messenger RNAs. A "nucleotide fragment" or an "oligonucleotide" are two synonymous terms designating a chain of nucleotide motifs characterized by an information sequence of the natural (oroptionally modified) nucleic acids and able to hybridise, like natural nucleic acids, with a complementary or substantially complementary nucleotide fragment under predetermined conditions of high stringency. The chain may contain nucleotide motifshaving a different structure to natural nucleic acids. A nucleotide fragment (or oligonucleotide) may for example contain up to 100 nucleotide motifs. It generally contains at least 8, and in particular at least 12 nucleotide motifs, furtherparticularly 18 to 35, and may be obtained from a natural nucleic acid molecule and/or by genetic recombination and/or by chemical synthesis. A nucleotide motif is derived from a monomer which may be a natural nucleotide of a nucleic acid whoseconstituent elements are a sugar, a phosphate group and a nitrogenous base chosen from among adenine (A), guanine (G), uracil (U), cytosine (C), thymine (T); or else the monomer is a nucleotide modified in at least one of the three preceding constituentelements; as an example, modification may occur either at the bases, with modified bases such as inosine which can hybridise with any base A, T, U, C or G, methyl-5-deoxycytidine, deoxyuridine, dimethylamino-5-deoxyuridine or any other modified base ableto hybridise, or at the sugar, for example the replacement of at least one deoxyribose by a polyamide (Nielsen P E et al., Science (1991) 254: 1497-1500], or at the phosphate group, for example through replacement by esters chosen from amongdiphosphates, alkylphosphonates and phosphorothioates. By "hybridisation" is meant the process during which, under suitable conditions, two nucleotide fragments having sufficiently complementary sequences are able to join together by stable, specifichydrogen bonds to form a double strand. Hybridisation conditions are determined by "stringency" i.e. the strictness of operating conditions. Hybridisation is more specific the higher the stringency. Stringency depends in particular upon the basecomposition of a probe/target duplex and on the extent of mismatch between two nucleic acids. Stringency may also be related to parameters of the hybridisation reaction, such as the concentration and type of ion species present in the hybridisationsolution, the type and concentration of denaturing agents and/or the temperature of hybridisation. The stringency of the conditions in which a hybridisation reaction must be conducted depends in particular upon the probes used. All this data is wellknown and the suitable conditions may possibly be determined in each case by routine experiments. In general, depending upon the length of the probes used, the temperature for the hybridisation reaction lies between approximately 20 and 65.degree. C.,in particular between 35 and 65.degree. C. in a saline solution at a concentration of around 0.8 to 1 M. A "probe" is a nucleotide fragment having hybridisation specificity under determined conditions to form a hybridisation complex with a nucleic acidhaving, in this case, a nucleotide sequence included either in a messenger RNA or in a DNA obtained by reverse transcription of said messenger RNA, the transcription product; a probe may be used for diagnosis purposes (capture and detection probes inparticular) or for therapeutic purposes. A "capture probe" is a probe that is or may be immobilised on a solid support by any appropriate means, for example by covalency, adsorption, or direct synthesis on a solid. Examples of supports includemicrotitration wafers and DNA chips. A "detection probe" is a probe labelled with a marking agent chosen for example from among radioactive isotopes, enzymes in particular enzymes able to act on a chromogenous, fluorigenous or luminescent substrate (inparticular a peroxidase or an alkaline phosphatase), chromophorous chemical compounds, chromogenous, fluorigenous or luminescent compounds, analogues of nucleotide bases and ligands such as biotin. A "species probe" is a probe enabling the specificidentification of the species of a bacterium. A "genus probe" is a probe enabling the specific identification of the genus of a bacterium. A "primer" is a probe having 10 to 100 nucleotide motifs for example and having hybridisation specificity underdetermined conditions for enzymatic amplification reactions. By "amplification reaction" is meant an enzymatic polymerisation reaction, for example in an amplification technique such as PCR, initiated by primer oligonucleotides and using a polymeraseDNA. By "sequencing reaction" is meant the obtaining of the sequence of a nucleic acid fragment or of a complete gene by means of an abortive polymerisation method using oligonucleotide primers and said dideoxynucleotides [Sanger F, Coulson A R (1975),J. Mol. Biol. 94: 441] or multiple hybridisations with multiple probes fixed on a solid support such as used in DNA chips for example.

The sequences of the rpoB genes of the bacteria Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus mutans and Streptococcus agalactiae have been described in the literature.

The inventors have determined the complete sequences of the rpoB genes of other bacterial species of genus Streptococcus and related genera: Streptococcus anginosus and Streptococcus equinus, Abiotrophia defectiva, and a very large portion of thegene for Streptococcus mutans and Enterococcus faecalis. These species were chosen by the inventors as representing the main genetic groups determined on the basis of the study on the 16S gene in bacteria of genus Streptococcus and related genera,encompassing all the species currently described in this genus, so that the alignment of the rpoB sequences obtained in these species would most probably encompass all the rpoB sequences of all the species of these bacterial genera, more precisely theyare therefore the most divergent species from a phylogenetic viewpoint among all the species currently described in this genus, so that the alignment of the rpoB sequences obtained in these species would most probably from a phylogenetic viewpointencompass all the rpoB sequences of all the species of this bacterial genus.

From these complete or almost complete sequences, and after numerous unsuccessful attempts such as reported in examples 1 and 2 below, the inventors have evidenced the following consensus and specific sequences SEQ ID no 6 and 7:

TABLE-US-00001 SEQ ID N.sup.o 6: 5'-AARYTNGGMCCTGAAGAAAT-3', and SEQ ID N.sup.o 7: 5'-TGNARTTTRTCATCAACCATGTG-3'

in which: N represents inosine or one of the 4 nucleotides A, T, C or G, R represents A or G, M represents A or C, and Y represents C or T, and the reverse sequences and complementary sequences.

The inventors have determined said sequences SEQ ID no 6 and 7 as being not only consensual between all the bacteria of genus Streptococcus and said 4 related genera, but also specific to the family of bacteria of genus Streptococcus and said 4related genera.

At the position corresponding to a nucleotide N, Y, M or R in sequences SEQ ID no 6 and 7, variable nucleotides are found in the complementary target sequences in relation to the species of the bacterium under consideration, but all the othernucleotides are conserved in all the species of bacteria of genus Streptococcus and of said 4 related genera.

Sequences SEQ ID no 6 and 7 so defined are present in the rpoB genes of all bacteria of genus Streptococcus and said 4 related genera, and are specific to the bacteria of genus Streptococcus and said 4 related genera, and can therefore providegenus probes or amplification primers to detect any bacterium of genus Streptococcus and of said 4 related genera.

For this purpose, one subject of the present invention is therefore an oligonucleotide which comprises a sequence of at least 8, preferably at least 12, further preferably between 18 and 35 nucleotide motifs, of which at least one sequence of 8,preferably 12, further preferably 18 consecutive motifs is included in one of the following sequences SEQ ID no 6 and 7:

TABLE-US-00002 SEQ ID N.sup.o 6: 5'-AARYTNGGMCCTGAAGAAAT-3', and SEQ ID N.sup.o 7: 5'-TGNARTTTRTCATCAACCATGTG-3'

in which: N represents inosine or one of the 4 nucleotides A, T, C or G, R represents A or G, M represents A or C, and Y represents C or T and the reverse sequences and complementary sequences.

Another subject of the invention is a mixture of oligonucleotides characterized in that it consists of an equimolar mixture of oligonucleotides of the invention, all having a different sequence and all comprising a sequence included in SEQ ID no6 or all comprising a sequence included in SEQ ID no 7.

More particularly, a further subject of the invention is a mixture of said oligonucleotides, consisting of an equimolar mixture of 32 oligonucleotides of different sequences each comprising at least 15, preferably at least 18 consecutivenucleotide motifs included in the following sequence:

TABLE-US-00003 SEQ ID n.sup.o 6: 5' AARYTNGGMCCTGAAGAAAT-3'

in which: R represents A or G, Y represents C or T M represents A or C, and N represents A, T, C or G and the reverse sequences and complementary sequences.

A further subject of the invention is a mixture of said oligonucleotides consisting of an equimolar mixture of 8 oligonucleotides having different sequences and each comprising at least 15, preferably at least 18 consecutive nucleotide motifsincluded in the following sequence:

TABLE-US-00004 SEQ ID n.sup.o 6: 5' AARYTNGGMCCTGAAGAAAT-3'

in which: R represents A or G, Y represents C or T M represents A or C, and N represents inosine and the reverse sequences and complementary sequences.

A further subject of the invention is a mixture of said oligonucleotides, consisting of an equimolar mixture of 16 oligonucleotides having different sequences and each comprising at least 15, preferably at least 21 consecutive nucleotide motifsincluded in the following sequence:

TABLE-US-00005 SEQ ID n.sup.o 7: 5' TGNARTTTRTCATCAACCATGTG-3'

in which: R represents A or G, and N represents A, T, C or G and the reverse sequences and complementary sequences.

A further subject of the present invention is a mixture of said oligonucleotides, consisting of an equimolar mixture of 4 oligonucleotides having different sequences and each comprising at least 15, preferably at least 21 consecutive nucleotidemotifs included in the following sequence:

TABLE-US-00006 SEQ ID n.sup.o 7: 5'-TGNARTTTRTCATCAACCATGTG-3'

in which: R represents A or G, and N represents inosine, and the reverse sequences and complementary sequences.

Said mixtures of oligonucleotides are able to hybridise with a complementary sequence included in the rpoB gene of all the bacteria of genus Streptococcus and said 4 related genera, and can therefore be used as a genus probe or as amplificationprimers for the detection or respectively the amplification of an rpoB gene fragment of said bacterium.

To prepare said equimolar mixture of oligonucleotides using oligonucleotide synthesis methods known to persons skilled in the art, an equimolar mixture is used of 4 or 2 nucleotides for the nucleotides corresponding to N or respectively K, N, Ror Y, namely: an equimolar mixture of the 4 nucleotides A, T, C and G for the nucleotides corresponding to N in which N represents A, T, C or G, and an equimolar mixture of the 2 nucleotides T and G for the nucleotides corresponding to K, an equimolarmixture of the 2 nucleotides A and C for the nucleotides corresponding to N, an equimolar mixture of the 2 nucleotides A and G for the nucleotides corresponding to R, and an equimolar mixture of the 2 nucleotides C and T for a nucleotide represented byY.

Hence an equimolar mixture is obtained of 32 (2.sup.3.times.4) and 16(2.sup.2.times.4) nucleotides of different sequences for the 2 sequences SEQ ID no 6 and 7 respectively.

In said equimolar mixtures of oligonucleotides according to the invention, since "N" represents inosine which is able to hybridise with any base or an equimolar mixture of the 4 bases A, T, C, G, the sequences SEQ ID no 6 and 7 are able tohybridise with the complementary sequence included in the rpoB gene of all bacteria of the Streptococcus genus and of the said 4 related genera.

In addition, these consensus sequences SEQ ID no 6 and no 7 flank hyper-variable sequences whose sequence is specific to each bacterium species of genus Streptococcus. These sequences flanked by SEQ ID no 6 and 7 may therefore be used as speciesprobe for the bacteria of genus Streptococcus and said 4 related genera.

In addition, the sequences SEQ ID no 6 and 7 were determined as flanking an rpoB gene fragment comprising a zone whose variable length is approximately 720 bp and as comprising the shortest sequences specific to each bacterium species of theStreptococcus genus and said 4 related genera.

The inventors were therefore able to evidence species probes for each of the examined 28 bacterial species of genus Streptococcus and said 4 related genera, corresponding to sequences SEQ ID no 8 to 35 described in example 2 below, flanked by theconsensus sequences SEQ ID no 6 and 7.

A further subject of the present invention is a rpob gene or gene fragment of a bacterium of genus Streptococcus or of one of said 4 related genera, except sequences SEQ ID no 11, 12, 14, and of the bacteria Streptococcus pyogenes, Streptococcuspneumoniae, Streptococcus mutans and Streptococcus agalactiae, the reverse sequences and complementary sequences, characterized in that it comprises a sequence such as described in sequences SEQ ID no 8 to 35 described in example 2.

A further subject of the invention is the complete sequence of the rpob gene of the bacteria Streptococcus anginosus, Streptococcus equinus and Abiotrophia defectiva such as described in sequences SEQ ID no 1 to 3, which can be used in particularfor a method of the invention.

A further subject of the present invention is the almost complete sequence of the rpob gene of the bacterium Enterococcus faecalis such as described in SEQ ID no 5, which can be used in particular for a method of the invention.

In sequences SEQ ID no 1 to 3 and 5 and 8 to 35 described in the sequence listing at the end of the description: nucleotide M represents A or C, nucleotide K represents T or G, nucleotide R represents A or G, nucleotide W represents A or T,nucleotide Y represents C or T, nucleotide N represents A, T, C, G or I nucleotide S represents C or G, nucleotide V represents A, C or G

The consensus sequences derived from SEQ ID no 6 and 7 evidenced according to the present invention, may be used as genus probe, as amplification or sequencing reaction primer in detection methods for bacteria of genus Streptococcus and said 4related genera, by molecular identification.

With the sequences derived from sequences SEQ. ID no 6 and 7 it is therefore not only possible to prepare genus probes for bacteria of genus Streptococcus and said 4 related genera, but also to detect and identify the species of said bacteriathrough amplification and sequencing using said sequences as primers.

The complete sequence of the rpoB gene may be used to identify the bacterium not only through the study of its primary sequence, but also through the study of the secondary and tertiary structures of the messenger RNA derived from transcriptionof the complete DNA sequence.

A further subject of the invention is an oligonucleotide or an rpoB gene fragment having a sequence included in or consisting of sequences SEQ ID no 8 to 35, hence including sequences SEQ ID no 11, 12, 14 and 22 of the bacteria Streptococcuspyogenes, Streptococcus pneumoniae, Streptococcus mutans and Streptococcus agalactiae respectively, and also among the oligonucleotides or fragments of reverse or complementary sequences such as defined above.

The inventors, after analysing the different sequences and comparing pair by pair all sequences SEQ. ID no 8 to 35, determined that the homology rate between two different sequences among said sequences SEQ ID no 8 to 35 is a maximum rate 99.3%. Below 99.3% homology between the sequences, they identify bacteria of different species. Consequently, a further subject of the invention is oligonucleotides or rpoB gene fragments having sequences included in or consisting of said sequences SEQ ID no 8to 35, the reverse sequences, the complementary sequences and sequences showing at least 99.3% homology (i.e. a similarity rate of at least 99.3% between the sequences) with respect to said sequences SEQ ID no 8 to 35, the reverse sequences andcomplementary sequences respectively.

The oligonucleotides, gene fragments and genes subject of the present invention have been described as comprising DNA sequences i.e. with nucleotides A, T, C and G. However, a further subject of the present invention is oligonucleotidescomprising corresponding RNA sequences, i.e. in which T is replaced by U.

In the present description, by "reverse sequences and complementary sequences" is meant the following sequences: the reverse sequence of said sequence, the complementary sequence of said sequence, and the complementary sequence of the reversesequence of said sequence.

Sequences SEQ ID no 1 to 35 may be prepared by genetic engineering and/or chemical synthesis, in particular by automatic synthesis, using techniques well known to persons skilled in the art.

One first application of an oligonucleotide of the invention is its use a probe for the detection, in a biological specimen, of bacteria of one of the species of genus Streptococcus and said 4 related genera, which comprises a nucleotide sequencein one of the sequences SEQ ID no 6 to 35 and their reverse or complementary sequences.

An oligonucleotide comprising sequences SEQ ID no 6 and 7 will be used as genus probe, and an oligonucleotide comprising a sequence included in or comprising one of sequences SEQ ID no 8 to 35 will be used as species probe.

More particularly, the subject of the present invention is an oligonucleotide comprising a sequence specific to a bacterium species of genus Streptococcus and said related genera, preferably having at least 20 consecutive nucleotides, furtherpreferably at least 30 consecutive nucleotides included in one of said sequences SEQ ID no 8 to 35, or optionally an equimolar mixture of said oligonucleotides having different sequences.

Preferably, said sequences included in one of sequences SEQ ID no 8 to 35, preferably having at least 20, further preferably at least 30 consecutive nucleotides included in one of said sequences SEQ ID no 8 to 35, form the shortest sequencesspecific to the different respective species which can be used as species probe for Streptococcus bacteria and for said 4 related genera under consideration.

The probes of the invention may be used for diagnostic purposes, as mentioned previously, by determining the formation or non-formation of a hybridisation complex between the probe and a target nucleic acid in the specimen, using all knownhybridisation techniques in particular "DOT-BLOT" techniques [Maniatis et al. (1982) Molecular Cloning, Cold Spring Harbor] DNA transfer techniques called "SOUTHERN BLOT" [Southern E. M., J. Mol. Biol. (1975) 98: 503], RNA transfer techniques called"NORTHERN BLOT", or so-called "sandwich" techniques in particular using a capture probe and/or a detection probe, said probes being able to hybridise with two different regions of the target nucleic acid, and at least one of said probes (generally thedetection probe) being able to hybridise with a target region that is specific to the species, the capture probe and the detection probe evidently having nucleotide sequences that are at least partly different.

The nucleic acid to be detected (target) may be DNA or RNA (the first obtained after PCR amplification). When detecting a target of double strand nucleic acid type, the latter must first be denatured before starting detection. The targetnucleic acid may be obtained using known methods for its extraction from a specimen to be examined. Denaturing of a double strand nucleic acid may be conducted using known chemical, physical or enzymatic methods, in particular by heating to anappropriate temperature, of over 80.degree. C.

To implement the above-mentioned hybridisation techniques, in particular the "sandwich" techniques, a probe of the invention called a capture probe is immobilised on a solid support, and another probe of the invention called a detection probe islabelled with a marking agent. Examples of supports and marking agents are those previously given.

Advantageously, a species probe is immobilised on a solid support, and another species probe is labelled with a marking agent.

Another application of an oligonucleotide of the invention is its use as nucleotide primer comprising a monocatenary oligonucleotide chosen from among oligonucleotides having a sequence of at least 12 nucleotide motifs included in one ofsequences SEQ ID no 6 to 35, which can be used in the synthesis of a nucleic acid in the presence of a polymerase using a known method, in particular by amplification methods using said synthesis in the presence of a polymerase (PCR, RT-PCR, etc). Inparticular, a primer of the invention may be used for the specific reverse transcription of a messenger RNA sequence of a bacterial species of genus Streptococcus and said 4 related genera to obtain a corresponding complementary DNA sequence. Saidreverse transcription may form the first stage of the RT-PCR technique, the following stage being PCR amplification of the complementary DNA obtained. Primers of the invention may also be used for specific amplification, by chain polymerisationreaction, of the total DNA sequence of the rpoB gene of a species of genus Streptococcus and said 4 related genera.

In one particular case, said primer comprising an oligonucleotide of the invention also comprises the sense or antisense sequence of a promoter recognized by a polymerase RNA (promoters T7, T3, SP6 for example [Studier F W, B A Moffatt (1986) J.Mol. Biol. 189:113]: said primers can be used in nucleic acid amplification methods using a transcription step such as, for example, NASBA or 3SR techniques [Van Gemen B et al. Abstract MA 1091, 7.sup.th International Conference on AIDS (1991) Florence,Italy].

A further subject of the invention is a nucleotide primer comprising an oligonucleotide chosen from among oligonucleotides having a sequence comprising one of sequences SEQ ID no 6 to 35 or a sequence included in SEQ ID no 6 to 35 which can beused for full or partial sequencing of the rpoB gene of any strain of a bacterial species of genus Streptococcus and said 4 related genera.

Full or partial sequencing of the rpoB gene in any bacterium of genus Streptococcus and related genera enables the identification of all bacteria of genus Streptococcus and of said 4 related genera by bio-computerized analysis of this sequence,and enables the recognition of new unknown bacterial species of Streptococcus and of said 4 related bacteria.

Preferably, for use as a primer or for sequencing rpoB genes, said mixture of oligonucleotides of the invention is used, and further preferably said mixtures of oligonucleotides consisting of sequences SEQ ID no 6 and SEQ ID no 7.

More precisely, the present invention provides a detection method by identification to detect a bacterium of one of the species of genus Streptococcus and of said 4 related genera, characterized in that the following are used: a complete oralmost complete rpoB gene of said bacterium according to the present invention and an rpoB gene or gene fragment of a bacterium Streptococcus pyogenes, Streptococcus pneumoniae, Streptococcus mutans and Streptococcus agalactiae comprising a sequence suchas described in sequences SEQ ID no 11, 12, 14 and 22 respectively, the reverse sequences and complementary sequences, which may be used in particular as species probe, and/or a said fragment of said rpoB gene of said bacterium according to the presentinvention, comprising a nucleotide sequence chosen from among one of sequences SEQ ID no 8 to 35, the reverse sequences and complementary sequences, which may be used in particular as species probe, and/or an oligonucleotide of the present inventioncomprising a sequence included in one of sequences SEQ ID no 8 to 35, the reverse sequences and complementary sequences, which may be used in particular as species probe, and/or an oligonucloetide or said mixture of oligonucleotides of the presentinvention comprising a sequence consisting of consecutive nucleotide motifs, included in one of sequences SEQ ID no 6 and 7, which may be used in particular as genus probe or amplification primer.

Preferably, in said detection method of the invention, the following are used: a said rpoB gene fragment of said bacterium comprising a sequence chosen from among one of sequences SEQ ID no 8 to 35 or an oligonucleotide having a sequence includedin one of said sequences SEQ ID no 8 to 35, the reverse sequences and complementary sequences, and/or at least one said mixture of oligonucleotides according to the present invention whose preferable sequences consist of sequences SEQ ID no 6 and 7, andtheir reverse sequences and complementary sequences in which further preferably N represents inosine.

In a first embodiment of a detection method of the invention, it is sought to evidence the presence of a bacterium of genus Streptococcus and said 4 related genera, and the following steps are performed in which: 1. at least one genus probecomprising a said mixture of oligonucleotides having sequences comprising or included in one of sequences SEQ ID no 6 and 7, the reverse sequences and complementary sequences according to the invention, is contacted with a specimen containing or possiblycontaining nucleic acids of at least one said bacterium of genus Streptococcus and of said 4 related genera, and 2. the formation or non-formation is determined of a hybridisation complex between said genus probe and the nucleic acids of the specimen,and the presence is determined of said bacterium of genus Streptococcus or of said 4 related genera if a hybridisation complex is formed.

In a second embodiment of a detection method for a bacterium of genus Streptococcus and said 4 related genera, the steps are performed in which: 1. Amplification primers, comprising said mixtures of oligonucleotides containing a sequenceincluded in said sequences SEQ ID no 6 and 7 reverse sequences and complementary sequences of the invention, are contacted with a sample containing or possibly containing nucleic acids of at least one said bacterium of genus Streptococcus and of said 4related genera, using: as 5' primer: a said mixture of oligonucleotides containing a sequence included in sequence SEQ ID no 6 or preferably consisting of said complete sequence SEQ ID no 6, or a complementary sequence of the invention, as 3' primer: asaid mixture of oligonucleotides containing a sequence included in sequence SEQ ID no 7 or preferably consisting of said complete sequence SEQ ID no 7, or respectively a complementary sequence of the invention. 2. The nucleic acids are amplified byenzymatic polymerisation reaction, and the occurrence or non-occurrence of an amplification product is determined, and in this way the presence is determined of said bacterium in the specimen if an amplification product is produced.

This second embodiment may be used to specifically detect the genus of a Streptococcus bacterium or said 4 related genera.

However, at step 2 of this second embodiment, it may be sought to specifically detect a given bacterium species of genus Streptococcus chosen from among the species Streptococcus mutans, Streptococcus oralis, Streptococcus pneumoniae,Streptococcus pyogenes, Streptococcus salivarius, Streptococcus sanguinis, Streptococcus suis, Streptococcus acidominimus, Streptococcus agalactiae, Streptococcus anginosus, Streptococcus constellatus, Streptococcus difficilis, Streptococcusdysgalactiae, Streptococcus equi, Streptococcus equinus, Streptococcus intermedius, Streptococcus mitis, Streptococcus bovis, Granulicatella adjacens, Abiotrophia defectiva, Enterococcus avium, Enterococcus casselliflavus, Enterococcus faecalis,Enterococcus faecium, Enterococcus gallinarum, Enterococcus sacharolyticus, Gemella haemolysins and Gemella morbillorum, as described in the variant of embodiment of a detection method specific to a species of said bacteria, given in the descriptionbelow.

As previously set forth in the introduction, the genera Streptococcus, Enterococcus, Granulicatella, Abiotrophia and Gemella comprise more bacterial species than those effectively sequenced in this work. However, the sequenced species werechosen so that they encompass all known species in these bacterial genera and are sufficient in number to demonstrate the application of the rpoB sequence to the identification of the species of these genera.

In a variant of embodiment of a method of the invention for specifically detecting a species of said bacteria, the steps are performed in which: 1. a specimen containing or possibly containing nucleic acids of at least one said bacterium iscontacted with at least one species probe consisting of said gene, said gene fragment or said oligonucleotide containing a sequence included in one of sequences SEQ ID no 8 to 35, preferably an oligonucleotide consisting of one of said sequences SEQ IDno 8 to 35, the reverse sequences and complementary sequences according to the invention, and 2. the formation or non-formation of a hybridisation complex is determined between said probe and the nucleic acids in the specimen, thereby determining thepresence of said bacterium in the specimen if a hybridisation complex is formed.

In another variant of embodiment of the method of the invention, in which it is sought to specifically detect a given species of a bacterium of genus Streptococcus and of said 4 related genera, chosen from among the 28 species cited above, themethod comprises the steps in which, in a specimen containing or possibly containing nucleic acids of at least one said bacterium: a) a sequencing reaction is conducted of an amplified rpoB gene fragment of said given bacterium using nucleotide primersconsisting of said mixtures of oligonucleotides containing sequences included in sequence SEQ ID no 6 as 5' primer, and in SEQ ID no 7 as 3' primer, the sequences preferably consisting of said sequences SEQ ID no 6 and 7, and their complementarysequences, and b) the presence or absence of the given species of said bacterium is determined by comparing the obtained sequence of said fragment with the sequence of the complete rpoB gene of said bacterium or the sequence of a rpoB gene fragment ofsaid bacterium containing said sequences no 8 to 35 and complementary sequences of the invention, thereby determining the presence of said bacterium in the specimen if the obtained fragment sequence is identical to the known sequence of the genus or ofthe rpoB gene fragment of said bacterium.

A further subject of the present invention is a diagnosis kit which can be used for a method of the invention, containing at least one said gene fragment or said oligonucleotide having a sequence included in or consisting of sequences SEQ ID no 8to 35, or a said oligonucleotide or mixture of oligonucleotides containing a sequence included in one of sequences SEQ ID no 6 and 7, and/or at least one said rpoB gene fragment of said bacterium comprising sequences SEQ ID no 8 to 35 and complementarysequences of the invention.

Advantageously, a kit of the present invention contains said oligonucleotides in the form of "biochips", i.e. fixed to solid supports, glass in particular, according to the method described in U.S. Pat. No. 5,744,305 (Affymetrix, Fodor et al)using the resequencing strategy described in application WO 95/11995 (Affymax, Chee et al) or according to the method described by A. Troesch et al. in J. Clin. Microbiol., vol. 37(1), p 49-55, 1999. The oligonucleotides synthesized on the "biochip"carry out re-sequencing of the hyper variable region of the rpoB gene. This method offers considerable advantage in terms of production costs with no detriment to quality of identification of the different species through the choice of theseidentification sequences. Preferably, these oligonucleotides fixed onto the "biochip" solid support comprise 10 to 30 bases, e.g. 20 bases, with an interrogation position located in the central region for example at position 12 with respect to the 3'end of the sequence for oligonucleotides with 20 bases. Another example consists of using oligonucleotides having 17 bases with 2 interrogation positions: one at position 10 and one at position 8. Other oligonucleotides have lengths of between 10 and25 nucleotides. The interrogation positions then vary according to the length of the oligonucleotide.

Analysis is conducted on the complete GeneChip.RTM. system (reference 900228, Affymetrix, Santa Clara, Calif.) which comprises the GeneArray.RTM. reader, the GeneChip.RTM. hybridisation oven, GeneChip.RTM. fluid station and GeneChip.RTM. analysis software.

An oligonucleotide of the invention may also be used as a gene therapy probe to treat infections caused by a strain belonging to a species of genus Streptococcus and said 4 related genera, said probe comprising an oligonucleotide such as definedpreviously. This gene therapy probe, able to hybridise on the messenger RNA and/or on the genomic DNA of said bacteria, may block translation and/or transcription and/or replication phenomena.

The principle of gene therapy methods is known and is based in particular on the use of a probe corresponding to an antisense strand: the formation of a hybrid between the probe and the sense strand is able to disrupt at least one of the geneticinformation decoding steps. Gene therapy probes can therefore be used as anti-bacterial medicines, making it possible to fight against infections caused by bacteria belonging to the species of genus Streptococcus and said 4 related genera.

Theinvention will be more readily understood with the help of the description given below, divided into examples relating to experiments conducted with a view to implementing the invention and which are given solely for illustrative purposes.

EXAMPLE 1

Sequence of the rpoB Gene of Three Species of Genus Streptococcus and Related Genera: Abiotrophia defectiva, Streptococcus anginosus and Streptococcus equinus

The complete sequence of the rpoB gene of bacteria belonging to the species of Abiotrophia defectiva, Streptococcus anginosus and Streptococcus equinus was determined by enzymatic amplification and automatic sequencing available for Streptococci. The choice of these species was based on analysis of the 16S tree which shows genetic divergence covering the entire phylogenetic tree for streptococci.

Strategy and Sequencing:

Several partial 510-bp sequences of rpoB genes are available from GenBank for the 10 following streptococcus species: Streptococcus intermedius, Streptococcus sanguinis, Streptococcus penumoniae, Streptococcus parasanguinis, Streptococcus oralis,Streptococcus mitis, Streptococcus cristalus, Streptococcus constellatus, Streptococcus anginosus, and Granulicatell adjacens [Majewski J., Zawadzki P., Pickerill P., Cohan F. M. and Dowson C. G. Barriers to genetic exchange between bacterial species:Streptococcus pneumoniae transformation. J. Bacteriol. 182, 1016-1023 (2000)], but the primers used by these authors only amplify a fraction of the species of genus Streptococcus, and it was therefore not possible to carry out our work on the basis ofthis data alone. It was therefore necessary to determine primers able to amplify all strains of streptococci, enterococci, Abiotrophia, Gemella and Granulicatella. These primers also had to flank a region showing sufficient genetic diversity so as tobe able to distinguish between two species. However, the alignment of these published partial sequences made it possible to determine the following common primers: (the numbering refers to the complete sequence of Streptococcus pyogenes)

TABLE-US-00007 SEQ ID n.sup.o 36: 5'-AGACGGACCTTCTATGGAAAA-3' (primer 748F) SEQ ID n.sup.o 37: 5'-GGACACATACGACCATAGTG-3' (primer 116R), and SEQ ID n.sup.o 38: 5'-GTTGTAACCTTCCCAWGTCAT -3' (primer 830R).

These primers allowed the sequencing of the central part of the rpoB gene with 714 bp for the five chosen species (Streptococcus equinus, Streptococcus mutans, Streptococcus anginosus, Enterococcus faecalis, and Abiotrophia defectiva. From thiscentral fragment, sequencing was continued using the so-called genome Walker technique.

Outside this published zone [Majewski J. et al, J. Bacteriol. 2002, 182, 1016-1023], the alignment of the two complete sequences available from GenBank (Streptococcus pneumoniae [GenBank access number AE008542] and Streptococcus pyogenes[GenBank access number AE006480] made it possible to choose the following primers:

TABLE-US-00008 SEQ ID n.sup.o 39: 5'-GTCTTCWTGGGYGATTTCCC-3' (primer 2215R) SEQ ID n.sup.o 40: 5'-ACCGTGCIGCWTGGTTRGAAT-3' (primer 2057R) SEQ ID n.sup.o 41: 5'-AACCAATTCCGYATYGGTYT-3' (primer 1252R) SEQ ID n.sup.o 42: 5'-AGIGGGTTTAACATGATGTC-3'(primer 371F) SEQ ID n.sup.o 43: 5'-AGIGCCCAAACCTCCATCTC-3' (primer 730F), and SEQ ID n.sup.o 44: 5'-CTCCAAGTGAACAGATGTGTA-3' (primer 585R)

With these primers, it was possible to extend the sequenced region for some of the five chosen strains. In fully unexpected manner, E. Faecalis is not amplified by these primers; but it was observed that the sequenced partial zone showedhomology with the rpob gene of Listeria monocytogenes, i.e. with a bacterium belonging to a different bacterial genus which could in no way be inferred from existing data, and we therefore chose primers in the rpoB gene of Listeria to amplify the rpoBgene of Enterococcus faecalis.

TABLE-US-00009 SEQ ID n.sup.o 45: 5'-TTACCAAACTTAATTGAGATTCAAAC-3' (primer 180F) SEQ ID n.sup.o 46: 5'-AGTATTTATGGGTGATTTCCCA-3' (primer 410F) SEQ ID n.sup.o 47: 5'-GGACGTTATAAAATCAACAAAAAATT-3' (primer 910F) SEQ ID n.sup.o 48:5'-AGTTATAACCATCCCAAGTCATG-3' (primer 2430R) SEQ ID n.sup.o 49: 5'-TGAAGTTTATCATCAACCATGTG-3' (primer 3280R) SEQ ID n.sup.o 50: 5'-CCCAAAACGTTGTCCACC-3' (primer 3360R)

The partial sequences so obtained for the five chosen strains (Streptococus equinus, Streptococcus mutans, Streptcoccus anginosus, Enterococcus faecalis, Abiotrophia defectiva) made it possible to choose the following primers:

TABLE-US-00010 SEQ ID n.sup.o 51: 5'-AACCAAGCYCGGTTAGGRAT-3' (primer 520R) SEQ ID n.sup.o 52: 5'-ATGTTGAACCCACTIGCGGTGCCAT-3' (primer 2881F)

for the sequencing of the end C- and N-zones by Genome Walker.

Sequencing was then complete as displayed by the determination of the encoding region and the alignment of the translated proteins of the nucleotide sequences with the two published rpoB proteins of Streptococcus pneumoniae and Streptococcuspyogenes.

Several potential consensus primers were investigated to obtain a fragment able to lead to the complete sequence of the rpoB genes by successive elongations from a series of specific primers.

In each of the above steps, a large number of attempts with theoretically or potentially suitable primers failed before the above-mentioned primers were determined enabling the amplification and sequencing in successive steps of the entirety ofthe rpoB genes described below.

The sequencing reactions were conducted using reagents from the kit: ABI Prism dRhodamine Dye Terminator Cycle Sequencing Ready Reaction Kit (Perkin Elmer Applied Biosystems) in accordance with the manufacturer's recommendations and following theprogramme: 30 cycles comprising a denaturing step at 94.degree. C. for 10 sec., a hybridisation step of the primer at 50.degree. C. for 10 sec. and an extension step at 60.degree. C. for 2 minutes. The sequencing products were separated byelectrophoresis on a polyacrylamide gel and 377 DNA sequencer (Perkin) and analysed to form consensus sequences using Sequence Assembler software (Applied Biosystems).

With this approach we were able to determine the complete sequence of the rpoB gene in two species of genus Streptococcus and in Abiotrophia defectiva:

EXAMPLE 2

Partial Sequencing of the rpoB Gene of 28 Species of Genus Streptococcus and Related Genera

From the alignment of the complete sequences of the rpoB gene in Streptococcus spp. and Abiotrophia defectiva in example 1 and those known in GenBank (Streptococcus pneumoniae AE008542 and Streptococcus pyogenes AE006480) a set of primers waschosen for the amplification and sequencing of a 709 to 740 bp fragment of this gene in 28 type strains of these bacterial genera. The sequences of these primers were:

TABLE-US-00016 SEQ ID n.sup.o 6: 5'-AARYTIGMCCTGAAGAAAT-3' SEQ ID n.sup.o 7: 5'-TGIARTTTRTCATCAACCATGTG-3'

Sequence SEQ ID no 7 was used as 3' primer and therefore represents the complementary reverse sequence of the direct strand represented in preceding sequences SEQ ID no 1 to 5.

These primers are incorporated with the DNA extracted from the bacteria during PCR under the following conditions: denaturing at 95.degree. C. for 1 min followed by 35 cycles comprising a denaturing step at 94.degree. C. for 10 sec, ahybridisation step at 52.degree. C. for 10 sec and an elongation step at 72.degree. C. for 30 sec.

The amplified products are sequenced with the same primers SEQ ID no 6 and SEQ ID no 7 under the following conditions: denaturing at 95.degree. C. for 1 min followed by 30 cycles comprising a denaturing step at 95.degree. C. for 30 sec. ahybridisation step at 52.degree. C. for 30 sec and a hybridisation step at 62.degree. C. for 1 min. The sequencing products are analysed on a ABI PRISM 3100 sequencer.

The inventors determined the position of these two primers SEQ ID no 6 and SEQ ID no 7, so as to observe the following criteria: 1--sequence flanked by these two primers specific to the species of the bacterium. This condition is verified afteralignment of the fragments of around 720 bp with all the sequences of the rpoB bacterial genes available in computerized data banks, 2--search for the shortest possible identification region to achieve the best possible increase in the sensitivity ofmolecular detection, 3--primer length of 18 to 22 bp, 4--sequence of primers showing a close melting temperature, 5--sequence of primers not enabling auto-hybridisation or complementarity

The obtained rpoB gene fragments of the bacterial species of genus Streptococcus and said related genera have approximately 720 (709 to 732) base pairs and their sequence is specific to each species of this genus therefore permitting molecularidentification of the bacteria of the 28 species tested, i.e.:

EXAMPLE 3

Blind Identification of a Collection of 20 Bacterial Strains Comprising 10 Strains of Bacteria Belonging to Genus Streptococcus and Related Genera

A collection of twenty strains belonging to the following bacterial species: Streptococcus pyogenes, Streptococcus sanguis, Granulicatella adjacens, Abiotrophia defectiva, Enterococcus avium, Enterococcus faecalis, Gemella haemolysans, Gemellamorbilorum, Streptococcus equi, Streptococcus anginosus, Staphylococcus aureus, Pseudomonas oleovorans, Mycobacterium avium, Bacillus cereus, Acinetobacter anitratus, Corynebacterium amycolatum, Klebsiella terrigena, Pasteurella, Lactobacillus rhamnosus,Staphylococcus was coded so as to conduct blind molecular identification of strains (the experimenter not having any a priori knowledge of strain identity) using the method described in the present patent application. Extraction of the nucleic acids andamplification of the rpoB gene fragment were performed as described in example 2 incorporating primers consisting of mixtures of 4 oligonucleotides which have sequences consisting of sequences SEQ ID no 6 (as 5' primer) and SEQ ID no 7 (as 3' primer)where N represents inosine, in a PCR amplification (FIG. 1). The sequencing of these 10 amplificates was conducted by incorporating into the sequencing reaction the primers SEQ ID no 6 and SEQ ID no 7 as described in example 2, and comparison of thesequences obtained with sequences SEQ ID no 1 to 5 and 8 to 35 enabled the 10 ten amplified strains to be identified as being Streptococcus pyogenes, Streptococcus sanguis, Granulicatella adjacens, Abiotrophia defectiva, Enterococcus avium, Enterococcusfaecalis, Gemella haemolysans, Gemella morbilorum, Streptococcus equi, Streptococcus anginosus. The decoding of these 10 strains showed 100% agreement between molecular identification using the method that is the subject of the invention and theidentification previously established by standard phenotype methods. This result illustrates the specificity of the set of primers SEQ ID no 6/SEQ ID no 7.

The other bacteria chosen because they are frequently isolated in human or animal clinical specimens and also possibly contain bacteria of genus Streptococcus were not amplified, thereby exhibiting the specificity of the primers used for theStreptococcus genus and said 4 related genera under the conditions of use of the invention for detecting bacteria of genus Streptococcus and said 4 related genera in comparison with bacteria of another genus.

FIG. 1 shows the PCR amplification products obtained from ten coded bacterial strains, comprising 7 strains belonging to genus Streptococcus and said 4 related genera (columns 2,3,4,7-11) and 3 bacterial strains of bacterial genera other thanStreptococcus and said 4 related genera (columns 5, 6 and 12). Columns 1 and 13 show the molecular weight marker. The amplification products are obtained after incorporating primers SEQ ID no 6 and SEQ ID no 7 described above, and are visualized bystaining with ethidium bromide after electrophoresis on agarose gel.
