Specific dna fragment of streptococcus agalactiae and molecules of nucleic acids related

摘要

Disclosed herein is newly-identified DNA sequence from Streptococcus agalactiae ("GBS") designated GBS3.1. Also disclosed are methods, oligonucleotide probes, amplification primers, and kits for the species-specific detection of S. agalactiae. Preferably, S. agalactiae is detected by amplifying the S. agalactiae nucleic acids using the disclosed amplification primers, and then detecting the amplified nucleic acids. In a more preferred embodiment, S. agalactiae nucleic acids are amplified and detected by thermophilic strand displacement amplification (tSDA).
