Pseudomonas aeruginosa in Post-operative Wound Infections in Ibadan, Southwest Nigeria

Abstract

The occurrence of post-operative wound infections was studied over a period of five months in the University College Hospital, Ibadan between February to July, 2003. Two hundred Surgical wounds were collected and routinely processed by Gram staining and culture in the Microbiology Laboratory. Of the 200 samples examined 189 (94.5%) were positive for bacterial pathogens while 11(5.5%) were bacteriologically sterile. Among the bacterial pathogens isolated, the percentage of Pseudomonas aeruginosa was 22.4%. More males (30.3%) than females (22%) were infected {P<0.05}. The organisms showed 100% sensitivity to Colistin sulphate, followed by Ofloxacin (83%), then Norfloxacin (81.1%) and Ciprofloxacin (79.2%). The need for continuous antimicrobial monitoring of clinical isolates of post-operative wound infection for drug resistance should be paramount to clinicians for proper selection of suitable antibiotics.
