Evidence Of Community Acquired Mrsa Occurrence Among Indian Patients With Primary Pyoderma Attending Tertiary Care Hospital – A Retrospective Study

Introduction: The CA MRSA gained much attention during mid 1990, after death of four children in Minnesota and North Dakota. The first reports in India on CA MRSA were reported during mid-2000s, whereas the present study reports MRSA among Community acquired pyoderma cases during mid-1990s. Methods: A total of 100 coagulase positive Staphylococcus aureus isolates, obtained from 185 pyoderma cases. Retrospectively, it is understood that the studied cases fulfilled the criteria for community acquired MRSA including no history of hospitalization, contact with hospitalized patients and previous antibiotic treatment. Results: Of 100 S. aureus isolates tested for methicillin resistance, 42% were found to be MRSA and 58% were MSSA. MRSA skin infections (89%) were found predominantly among children and young youths. The demographic details of the pyoderma cases show that, 67% of cases had contact with the crowded community setups (school going children). Impetigo (46%), folliculitis (32%) and furunculosis (20%) were found to be the commonest infections in this study. Phage typing of S. aureus showed all four phage groups and mixed groups. Conclusion: Retrospectively, it is evident from the existing demographic data and scientific data of the study, that in India the MRSA were circulating in community settings during 1990s, its first reports in USA.
