This study provides what we believe to be the first report of the presence of EMRSA-15 and its variants isolated from nasal swabs from 13 healthy and diseased individuals in India. The majority of the isolates belonged to staphylococcal cassette chromosome mec (SCCmec) type IV and spa type t852, whilst four isolates were non-typable and heterotypic for the presence of the mecA gene. All non-typable isolates were positive for the orfX gene by PCR and belonged to spa types t005 and t2986. They may have variant SCCmec cassettes indicating genetic changes occurring in the Indian EMRSA-15. All isolates were positive for Panton-Valentine leukocidin and toxic shock syndrome toxin, which is a cause for concern. In addition to soft-tissue infections, the EMRSA-15 isolates from patients were also responsible for meningitis and brain abscesses, which is quite rare.
