Post-operative wound infections remain a serious problem in spite of modern standards of pre-operative preparation, antibiotic prophylaxis and operative technique. This study was undertaken to Isolate aerobic bacterial pathogens from clinically suspected post-operative wound infections and to determine their antibiogram. Samples that were sent to Microbiology laboratory from clinically suspected cases of post-operative wound infections were processed further. The bacteria isolated on aerobic culture were identified to the species level by standard biochemical tests. Antibiotic sensitivity testing, phenotypic identification of MRSA and ESBL producers were done as per CLSI guidelines. Overall incidence of post-operative wound infection was 1.7%. Majority of the patients (53.66%) presented with SSI during the post-operative period of 3-10 days. 49 samples showed culture positivity out of 82 infected cases. S.aureus was the predominant isolate (73.47%) followed by E.coli, K.pneumoniae, P.aeruginosa and P.mirabilis. MRSA accounted for 22.22%. All the S.aureus isolates were sensitive to Linezolid and Vancomycin. 75% of Enterobacteriaceae produced ESBL among which 66.67% were E.coli and 33.33% were K.pneumoniae. Marked resistance of isolates to commonly used antibiotics indicates the need for judicious use of these drugs to prevent the emergence of multi drug resistant strains. Proper infection control measures and a sound antibiotic policy are necessary to reduce post-operative wound infections.
