    Heterogeneity exists among Group a Streptococcus emm types worldwide. In 2003, we observed 11 circulating emm types in northern region of India, of which emm 81 was found to be the predominant type (17.5%). As emm 81 has been reported to be associated with invasive diseases in western countries, hence, in the present study, attempts were made to study the virulence potential of these isolates from skin and throat samples. Isolates were screened for nine fi bronectin binding protein (FBP) genes, evaluated for adherence & invasion potential along with drug resistance to various commonly prescribed antibiotics for treatment. Throat isolates showed higher distribution of FBP genes as compared to skin isolates. All the isolates were found to be positive for sciB and prtF15; 92.9% for sfb and fba, 78.6% for sciA; ..
