    Abstract:
    There are increasing numbers of reports of community-acquired Staphylococcus aureus being resistant to methicillin. The present study was undertaken as no such reports are available for the developing nations. In a prospective study, between June to December 2001, at the Karnataka Institute of Medical Sciences, Hubli, Karnataka, India, methicillin-resistant S. aureus (MRSA) isolates were tested for clindamycin-susceptibility, a surrogate marker for community-acquired strains. Patients with clindamycin-susceptible isolates were interviewed to determine if they had acquired them in the community and also to identify any risk factors. Of the 116 patients with S. aureus infection, 18.1% had infection with methicillin-resistant strains. Clindamycin-susceptible MRSA accounted for 61.9% of cases. Among these, 46.1% patients were confirmed to have acquired the MRSA from the community, based on inclusion criteria. The community-acquired MRSA were susceptible to multiple antibiotics, as compared to nosocomial isolates. Except for one patient with diabetes mellitus, no other patient had any known risk factor for acquiring MRSA. As significant numbers of MRSA infections are being acquired from the community, treatment options for S. aureus infections may need to be reviewed. Effective infection control programs for the community should be considered to prevent the spread of these infections.
