Common aerobic bacteria in post operative wound infection and their sensitivity pattern

Two hundred and four post-operative patients were examined and pus samples were collected with sterile cotton swabs from 64 patients with infected wounds. The samples were cultured aerobically and the isolates were identified as per standard methods. The prevalence rate of post-operative wound infection were 31.37% and the total number of bacterial isolates were 76 (37.25%). The isolates were identified up to their species level & they were E. coli, Staph. aureus, Kl. Pneumoniae, Ps. aeruginosa. Pr. vulgaris and S. pyogenes. Gram negative bacilli were the predominant organisms and among them E. coli was the most common. In antimicrobial susceptibility test Gentamycin and Cephalexin were found sensitive.
