Studies on post-operative wound infection: isolation of microorganisms and their antibiotic sensitivity.

Present study was undertaken to determine the relative incidence of different micro-organisms in postoperative wound infections and their in vitro antibiotic sensitivity. Swab samples from 50 patients were examined. The per cent incidence of different micro-organisms was: Gram-negative bacilli 33.34, Staphylococcus spp. 30.67, Bacillus spp. 13.33, Streptococcus spp. 12.00, Candida spp. 5.33 and Corynebacterium spp. 5.33. Gentamiein was found to be the drug of choice as micro-organisms from 81.25 per cent cases were sensitive to it. The least effective drugs were streptomycin and oxytetracyclinc each inhibiting the growth of micro-organisms in 14.58 per cent cases (JPMA 30:163, 1980).
