    Bacterial agents of abdominal surgical site infections in Lagos Nigeria
    (2009) Mofikoya, B.O.; Neimogha, M.I.; Ogunsola, F.T.; Atoyebi, O.A.
    Background: Infection continues to be a major complication of abdominal surgeries with significant increased costs, morbidity and potential mortality. Identifying the agents of abdominal wound infection and instituting appropriate measures will go a long way in reducing this problem. Objective: A prospective study of the aetiological agents of abdominal wound infections at the Lagos University Teaching Hospital was designed to identify the organisms involved and document their antibiotic sensitivity pattern. Methods: Swabs of the clinically infected wounds detected in a population of 144 consecutively studied patients were taken and cultured for both aerobic and anaerobic bacteria using standard microbiologic methods. Antibiotic sensitivity pattern was also determined for the aerobic organisms cultured. Results: 25(17.4%) of the 144 patients studied developed surgical site infections. Pseudomonas was the most frequently cultured aerobic organism in 28% (n=7 )of the cultures, while Bacteroides species was the most common anaerobe isolated. It was found in 64% (n=14)of the infected patients. Over 80% of the organisms demonstrated less than 50% sensitivity to the tested antibiotics. Conclusion: The study showed that gram negative bacteria and anaerobes are the majors agents of abdominal surgical site infections in Lagos, Nigeria.
