## Abstract

The present invention provides oligonucleotide primers and a method of using these primers for identification of the species of an organism, wherein the identification includes amplification of a variable polynucleotide sequence encoding a highly conserved region of a heat shock polypeptide.

## Claims

### Claim 1

A genomic polynucleotide locus which is defined by being amplified by primers having a sequence:
5'-GAIIIIGCIGGIGA(T/C)GGIACIACIAC-3' (SEQ. ID NO: 3) and
5'-(T/C)(T/G)I(T/C)(T/G)ITCICC(A/G)AAICCIGGIGC(T/C)TT-3' (SEQ ID NO:4)
wherein the amplified polynucleotide locus from one species does not hybridize under high stringency conditions with a polynucleotide locus from another species amplified by primers having a sequence:
5'-GAIIIIGCIGGIGA(T/C)GGIACIACIAC-3' (SEQ ID NO:3) and
5'-(T/C)(T/G)I(T/C)(T/G)ITCICC(A/G)AAICCIGGIGC(T/C)TT-3' (SEQ ID NO:4).
2.

### Claim 2 (depends on 1)

The genomic locus of claim 1, wherein the locus encodes a heat shock polypeptide.

### Claim 3 (depends on 1)

Isolated oligonucleotide primer(s) for use in the identification of the species of an organism wherein the primer hybridizes with a target polynucleotide sequence consisting of the sequence selected from the group consisting of:
5'-GTTGTCGTACC(G/A)TCACCAGCAATTTC-3' (SEQ. ID NO:1),
5'-AA(G/A)GCGCCTGGTTT(C/T)GGTGAT(C/A)(G/A)(A/T/C/G) (C/A)(G/A)-3' (SEQ. ID NO:2),
5'-GTIGTIGTICC(A/G)TCICCIGCIIIITC-3' (SEQ ID NO:93), and
5'-AA(A/G)GCICCIGGITT(T/C)GGIGAI(A/C)(A/C)I(A/C)(A/G)-3' (SEQ ID NO:94),
and sequences complementary thereto wherein the primers amplify the genetic locus of claim 1.

### Claim 4 (depends on 3)

The primer of claim 3, wherein the primer is
5'-GAIIIIGCIGGIGA(T/C)GGIACIACIAC-3' (SEQ ID NO:3) or
5'-(T/C)(T/G)I(T/C)(T/G)ITCICC(A/G)AAICCIGGIGC(T/C)TT-3' (SEQ ID NO:4).
5.

### Claim 5 (depends on 3)

The primer of claim 3, wherein the organism is a microorganism.

### Claim 6 (depends on 5)

The primer of claim 5, wherein the organism is a prokaryote.

### Claim 7 (depends on 6)

The primer of claim 6, wherein the prokaryote is a member of a genus selected from the group consisting of Staphylococcus, Pseudomonas, Escherichia, Bacillus, Salmonella, Chlamydia, Helicobacter, and Streptococcus.

### Claim 8 (depends on 7)

The primer of claim 7, wherein the species of the genus is selected from the group consisting of S. haemolyticus, S. epidermidis, S. lugdunensis, S. hominis, E. coli, B. subtilis, and P. aeruginosa.

### Claim 9

A kit useful for the isolation of target DNA for identification of the species of an organism, the kit comprising means for amplifying target DNA, said means comprising the necessary enzyme(s) and oligonucleotide primers for amplifying said target DNA from the organism or a cell of the organisms said primers consisting of a sequence:
5'-GAIIIIGCIGGIGA(T/C)GGIACIACIAC-3' (SEQ ID NO:3) and
5'-(T/C)(T/G)I(T/C)(T/G)ITCCC(A/G)AAICCIGGIGC(T/C)TT-3' (SEQ ID NO:4).
10.

### Claim 10 (depends on 9)

The kit of claim 9, wherein the target flanking 5' and 3' polynucleotide sequence has the sequence selected from the group consisting of:
5'-GTTGTCGTACC(G/A)TCACCAGCAATTTC-3' (SEQ ID NO:1)
5'-AA(G/A)GCGCCTGGTTT(C/T)GGTGAT(C/A)(G/A)(A/T/C/G) (C/A)(G/A)-3' (SEQ ID NO:2),
5'-GTIGTIGTICC(A/G)TCICCIGCIIIITC-3' (SEQ ID NO:93), and
5'-AA(A/G)GCICCIGGITT(T/C)GGIGAI(A/C)(A/G)I(A/C)(A/G)-3' (SEQ ID NO:94),
and sequences complementary thereto.
