Bacteriological profile of post-surgical wound infection along with special reference to MRSA in central india, indore

Post operative wound infections have been found to pose a major problem in the field of surgery. Advances in control of infection have not completely eradicated this problem because of development of drug reistance. The present study was carried out in Index Medical College hospital, one year study. 100 patients were recruited who underwent surgery in the orthopedic, obstetrics and gynecology and surgical departments. Gram positive organisms were more prevalent than gram negative bacteria accounting for 47(67.14%) and 23(32.85%) of isolates respectively. The three most commonly isolated bacterial species were S. aureus 41(58.6%) ,Pseudomonas aeruginosa 10(14.3%) and E.coli 06(8.6%). Out of 41 Coagulase positive Staphylococcus aureus, 20 (48.78%) were Methicillin resistant and 21 (51.21%) were methicillin sensitive strains. MRSA were found to be highly resistant to many antibiotics showing only intermediate sensitivity to cefazoll in (50%) and chloramphenicol(55%).
