Background: Pseudomonas. aeruginosa is an established cause of nosocomial infections among surgical patients and infants in neonatal intensive care units. Objective: We aimed, firstly to identify the prevalence of P. aeruginosa and other causative agents from wounds and other body sites (hands, groins, axillae, umbilicus and drains) and secondly to investigate the resistance patterns of antimicrobial susceptibility against various antibiotics. Materials and Methods: The study was carried out in Departments of General Surgery and Medical Laboratory in Tripoli Central Hospital, Tripoli, Libya over a period of 6 months from March through August 2007. A total of 792 clinical samples were taken during the examination from several sites of 150 patients and transported immediately to the laboratory then inoculated directly into selective on MacConkey agar and standard bacteriological media. The isolates were identified and antimicrobial susceptibility testing was performed by the disc diffusion method according to National Committee for Clinical and Laboratory Standards (NCCLS) guidelines. Results: 336 different bacterial isolates were identified in wounds and other body sites. In general, P. aeruginosa was the commonest isolate (35.7%) followed by Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae (29.2%, 9.2%, and 8.9%) respectively. In particular, P. aeruginosa was the most common bacteria isolated in samples from diabetic foot disease reaching 80.6% of total isolates. Conclusion: P. aeruginosa was found to be quite common in our surgical patients and it has emerged as one of the most problematic Gram negative pathogens. Hands of the patients were commonly colonized by different bacteria. Resistance rates to frequently used antibiotics were high. Microbiology sensitivity results should guide the use of proper antibiotic drugs.

Key-words:

Pseudomonas aeruginosa - nosocomial infections - diabetic foot disease
