Abstract

The present invention provides compositions, kits and methods for rapid identification and quantification of bacteria by molecular mass and base composition analysis.

Claims

1. An oligonucleotide primer pair comprising a forward primer and a reverse primer, wherein said forward primer comprises the sequence of SEQ ID NO:

318, and wherein said reverse primer comprises a sequence 95% identical to SEQ ID NO;

1300.

2. The oligonucleotide primer pair of claim 1 wherein said forward primer is SEQ ID NO:

318.

3. The oligonucleotide primer pair of claim 1, wherein said reverse primer comprises the sequence of SEQ ID NO:

1300.

4. The oligonucleotide primer pair of claim 1 wherein said reverse primer is SEQ ID NO:

1300.

5. The oligonucleotide primer pair of claim 1 wherein at least one of said forward primer and said reverse primer comprises at least one modified nucleobase.

6. The oligonucleotide primer pair of claim 5 wherein at least one of said at least one modified nucleobase is a mass modified nucleobase.

7. The oligonucleotide primer pair of claim 6 wherein said mass modified nucleobase is 5-Iodo-C.

8. The composition of claim 6 wherein said mass modified nucleobase comprises a molecular mass modifying tag.

9. The oligonucleotide primer pair of claim 5 wherein at least one of said at least one modified nucleobase is a universal nucleobase.

10. The oligonucleotide primer pair of claim 9 wherein said universal nucleobase is inosine.

11. The oligonucleotide primer pair of claim 1, wherein at least one of said forward primer and said reverse primer comprises a T residue at its 5′

end.

12. A kit for identifying, determining one or more characteristics of, or detecting a Staphylococcus aureus bioagent comprising the oligonucleotide primer pair of claim 1 and at least one additional primer pair designed to hybridize to a Staphylococcus aureus gene encoding arcC, aroE, gmk, pta, yqi, or a combination thereof.

13. The kit of claim 12 further comprising at least one other additional primer pair designed to hybridize to a Staphylococcus aureus gene encoding mecA, mecR1, pvluk, or a combination thereof.
