PREVALENCE OF METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS IN WESTERN TAMILNADU

Humans are natural reservoir for Staphylococcus aureus, and asymptomatic colonization is far more common than infection. Colonization byStaph.aureusmay be persistent can last years. Recent reports of strains Methicillin Resistant aureus (MRSA) isolated from community have led speculation that the epidemiology S. changing .Usually, MRSA infections havebeen a concern among hospitals decades now revealthat acquired increasing . The could possibly arisen as consequence resistance gene transfer hospital (nosocomial) donor into susceptible recipient. With appropriate analysis andrecipient chromosomes, it possible to determine whether these newly identified communityacquired wild or self-supporting.The present study was conducted with total sample 1296 wound other skin infection samples were collected different in western Tamilnadu. specimens inoculated blood agar isolation S.aureus by using standard method based on colony morphology, Gram's stain, catalase coagulase test. A 258 isolates confirmed S.aureus. These processed following three techniques,(i) oxacillin, cefoxition disk diffusion method, (ii) cultured MeRSA plate, (iii) Vitek 2 fully automated ID AST system detection mecA producer. 34 out strains.
