Abstract

The invention provides methods to detect group B streptococcus (GBS) in biological samples using real-time PCR. Primers and probes for the detection of GBS are provided by the invention. Articles of manufacture containing such primers and probes for detecting GBS are further provided by the invention.

Claims

1. An article of manufacture, comprising a pair of pts primers, a pair of pts probes, a donor fluorescent moiety and a corresponding acceptor fluorescent moiety, wherein said pair of pts primers comprises a first pts primer and a second pts primer, wherein said first pts primer consists of the sequence 5′

-TGA GAA GGC AGT AGA AAG CTT AG-3′

(SEQ ID NO;

1), and wherein said second pts primer consists of the sequence 5′

-TGC ATG TAT GGG TTA TCT TCC-3′

(SEQ ID NO;

2), wherein said pair of pts probes comprises a first pts probe and a second pts probe, wherein said first pts probe consists of the sequence 5′

-CAA ATT AAA GAG ACT ATT CGT GCA A-3′

(SEQ ID NO;

3), and wherein said second pts probe consists of the sequence 5′

-CAA GTA AAT GCA GAA ACA GG-3′

(SEQ ID NO;

4).

2. The article of manufacture of claim 1, wherein said first pts probe is labeled with said donor fluorescent moiety and wherein said second pts probe is labeled with said corresponding acceptor fluorescent moiety.

3. The article of manufacture of claim 2, further comprising a package insert having instructions thereon for using said pair of pts primers and said pair of pts probes to detect the presence or absence of Group B Streptococcus (GBS) in a sample.
