Detection of “Xisco” gene for identification of Streptococcus pneumoniae isolates

We describe a PCR-assay differentiating Streptococcus pneumoniae from closely-related species of the Mitis group of the genus Streptococcus and identification of pneumococcus clinical isolates, based on the “Xisco” gene discriminatory marker. The complete “Xisco” gene sequence was observed in all S. pneumoniae genomes analyzed and absent in all non-pneumococcus genomes.
