Aerobic bacterial study of postoperative lower segment cesarean site wound infection

Abstract

INTRODUCTION: Cesarean section wound infection illustrates a significant load to the health system as it carries an increased risk of infection as compared to normal vaginal delivery. Hence, it is necessary to identify the agents responsible as well as their extent of susceptibility for commonly used antibiotics. MATERIALS AND METHODS: The study was carried out at the Department of Microbiology, Jawaharlal Nehru Medical College. The specimens were inoculated on the blood and MacConkey agar. The colonies were identified by their morphological characteristics and the biochemical tests, antibiotic susceptibility test was carried for the isolated aerobic bacterial isolates. RESULTS: In the present study, Staphylococcus aureus (13, 56.68%) was the most common pathogen isolated, followed by Klebsiella pneumoniae (5, 21.9%). Gram-positive isolates showed greater sensitivity to tetracycline 11 (73.33%), followed by doxycycline (11, 73.33%) and clindamycin (9, 60%). Gram-negative bacteria showed the highest sensitivity meropenem (7, 77.78%), imipenem (6, 66.66%), and piperacillin + tazobactam (6, 66.66%). CONCLUSION: Frequent antimicrobial audit and qualitative research could give an insight into the current antibiotic prescription practices and the factors governing the same.
