Antibiotics Susceptibility Pattern of Pseudomonas aeruginosa Isolated from Wounds in Patients Attending Ahmadu Bello University Teaching Hospital, Zaria, Nigeria

Abstract

This work investigated the prevalence and antibiotics sensitivity of Pseudomonas aeruginosa isolated from wounds of patients attending Ahmadu Bello University Teaching Hospital (ABUTH), Zaria-Nigeria. One hundred Isolates were characterized and identified from the specimens using standard microbiological methods. The results of the isolation and identification showed that 55(55%) were Gram-negative organisms and 44 (44%) were Gram-positive. Klebsiella species and Pseudomonas aeruginosa accounted for 25% of the Gramnegative organisms, followed by Proteus species 19%, Klebsiella species 14% and Escherichia coli accounts for 11%, while Staphylococcus aureus 44% was the predominant Gram-positive organism. Antibiotic susceptibility pattern was determined using the disc diffusion method where the susceptibility of Pseudomonas aeruginosa isolated in wounds was observed. The highest sensitivity was observed for ofloxacin, moderate susceptibility was observed for ampicillin, cefuroxime and ceftriazone. The results obtained indicated strong resistance to cotrimoxazole, amoxicillin tetracycline and augmentin. There is the need for routine antibiotic sensitivity check.
