Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) has been a major cause of nosocomial infections since the 1960s. Currently, MRSA can be segregated into two subgroups: the healthcare associated MRSA (HA-MRSA) and community associated MRSA (CA-MRSA) The aim of our study is to identify the CA and HA MRSA in clinical isolates from a tertiary care hospital.

Staphylococci isolated from different clinical specimens were studied by routine standard biochemical tests and antibiogram and MRSA thus isolated were taken in the present study. Based on the patient history, biochemical tests and antibiogram CA-MRSA & HA-MRSA were grouped.

A total of 200 S.aureus were studied over a period of one year, 111 (55.5%)isolates were MSSA (Methicillin sensitive Staphylococcus aureus) and 89 isolates were Methicillin-resistant Staphylococcus aureus (MRSA) strains accounting to 44.5% MRSA thus isolated where identified as CA 31(35.22%) out of 89 isolates, while HA was 58(65.9%)

In this study HA-MRSA is more predominant than CA-MRSA. Further molecular study has to be done to determine the type of SCC mecA gene and PVL gene.
