Abstract
Wound infections inflict clinical and societal consequences on the patients, but its bacteriological characteristic varies with different factors. Therefore, effective treatment and management of wound infections in hospital and community setting will require detailed epidemiological knowledge of the infecting bacterial pathogens and their antibiogram peculiar to the environment. Based on this information, we examined the prevalence and antibiogram of bacterial pathogens isolated from wound infection cases seen at the hospital over the study period. A total of 392 wound swabs/ and pus of different types of wound infections from different anatomical sites and associated clinical conditions were analyzed by standard bacteriological methods. Of the 392 clinical specimens analyzed, 301(76.8%) yielded at least one bacterial pathogen, 25(6.4%) polymicrobial, no anaerobes identified and 91(23.2%) yielded no bacterial growth, gender distribution, 204(67.8%) males and 97(32.2%) females, and majority of pathogens were recovered from septic wound infections. Overall, 7 different bacterial pathogens were identified 5(71.4%) gram-negative bacteria isolates and 2(28.6%) gram-positive bacterial isolates]. Staphylococcus aureus accounted for majority of the bacterial pathogens isolated, 162(53%) followed by coliforms 62(21%) and Pseudomonas aeroginosa 57(19%). The bacterial pathogens demonstrated high resistance to ampicillin(78%), amoxicillin(66%), and cotrimoxazole(78%), in contrast to high sensitivity pattern observed with fluoroquinolones ( ofloxacin 83%,, norfloxacin 71%, ciprofloxacin 78%), erythromycin 72%, chloramphenicol 62%, gentamycin 58% and ceftazidime 60%. The relatively high number of wound infection cases seen within the study period is of public health concern, while the low number of bacterial pathogens isolated underscores the need for improvement in the laboratory diagnostic approach for effective treatment and management of wound infections.
