Diagnostic utility of multiplex PCR for direct detection and serotyping of group B streptococci from clinical specimens.

Multiplex PCR analysis of 348 recto-vaginal swabs from non-pregnant women revealed 33 % GBS colonization, with serotype V predominant. The study highlights the utility of multiplex PCR as a rapid and accurate diagnostic tool for detecting and serotyping Group B Streptococci directly from clinical specimens, supporting its role in surveillance, infection control, and guiding vaccine strategies in this underrepresented population.
