 en Pattern of pathogens from surgical wound infections in a Nigerian hospital and their antimicrobial susceptibility profiles
Akinkunmi, Ezekiel Olugbenga; Adesunkanmi, Abdul-Rashid & Lamikanra, Adebayo

Abstract

Background: In surgical patients, infection is an important cause of morbidity and mortality. A prospective study to find the pattern of microorganisms responsible for post operative wound infections and their antibiotic susceptibility profile was therefore conducted. Setting and
Methods: Surgical wards in Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Isolation, identification and antimicrobial susceptibility screening of organisms were done employing standard microbiological techniques.
Results:Bacterial pathogens were isolated from all the specimens while the yeast Candida check for this species in other resources species (spp) was isolated from 12.4%. Staphylococcus aureus check for this species in other resources was the most frequent organism isolated accounting for 23 (18.3%) of a total of 126 isolates. Other organisms were Pseudomonas aeruginosa check for this species in other resources and Bacillus check for this species in other resources spp 11.1% each; Escherichia coli check for this species in other resources 10.3%; Candida spp 8.7%; Coagulase negative staphylococci 8.7%; Pseudomonas check for this species in other resources spp 6.3%; Serratia odorifera check for this species in other resources 4.7%; Bacteroides check for this species in other resources 4.0%; Enterococcus check for this species in other resources spp 3.2%; the remaining isolates were other enterobacteria. Sensitivity of the bacterial isolates to antibiotics varied. In general, resistance to the β-lactam antibiotics was above 98%, whilst more than 70% of isolates were resistant to erythromycin, fusidic acid and tobramycin.
Conclusions:The infections were polymicrobic and multidrug resistant. The quinolones, ciprofloxacin and ofloxacin, should be used as frontline drugs in the management of surgical wound infections at the hospital.
