community acquired methicillin resistant Staphylococcus aureus in new patients attending a government hospital in Gangtok, Sikkim.

Journal of Pharmaceutical and Biomedical Sciences 06/2012; 19(19):1-3.


Prevalence of methicillin resistant Staphylococcus aureus (MRSA) is increasing in the community and has become an emerging public health problem. Community acquired MRSA (CA-MRSA) strains differ from Hospital acquired MRSA (HA-MRSA) by causing aggressive infections like furunculosis and necrotizing pneumonia in otherwise young, healthy individuals Aim - This study was carried out to determine the prevalence of CA-MRSA in patients attending hospital from April 2010 till March 2011. Materials and Methods - 2,282 clinical samples from outpatient and hospitalized patients were screened for MRSA. CA-MRSA were identified based on the CDC definition for community acquired infection. Antibiotic resistance pattern was studied by using the Kirby baeur disk diffusion method. Risk factors for hospital associated infections were recorded Results - Of the 184 strains of S. aureus isolated, 29.3% were MRSA and 48.14% was CA-MRSA. Conclusion Methicillin resistance is an increasing menace and routine screening of all isolates is necessary.
