Microbial profile of wound infections in A Nigerian Teaching Hospital

Background: This study set out to investigate the aerobic and facultative anaerobic microbial profile of wound infections in the University of Port Harcourt Teaching Hospital. Methods: A total of 202 wound swabs samples were randomly collected from both in and out-patients presenting at the facility. One hundred and thirteen(55.9%) of the samples were collected from males while 89(44.6%) were from females. The age of the patients ranged from 32 days to 80 years. Samples were processed following standard operating protocols in the microbiology laboratory. Results: Of the 202 samples examined, 164(81.2%) had microbial isolates while 38(18.8%) yielded no growth. Among the 164 samples with positive microbial growth, 124(75.6%) had single isolates while 40(24.4%) had polymicrobial growth. Of the 113 males studied, 90(79.7%) had microbial growth while 23(20.4%) had no growth. Similarly, of the 89 females studied, 74(83.2%) had microbial growth while 15(16.9%) had no growth. Furthermore, the total microbial isolates from the study was 206. Gram-negative bacterial organisms accounted for 124(60.1%) as against 82(39.9%) from the Gram-positive′s (p
