Identification of oral peptostreptococcus isolates by PCR-restriction fragment length polymorphism analysis of 16S rRNA genes

Oral Peptostreptococcus isolates tentatively identified by conventional microbiological culture methods were identified to the species level by a combination of PCR amplification of 16S rRNA genes and restriction enzyme analysis of the amplified products. This method is a reliable and rapid alternative to conventional methods for identification of these bacterial species.
