Abstract :

This study included 1000 surgery patients with signs and symptoms indicative of wound infections, who presented over the course of 5 years. Bacterial pathogens were isolated from 712 individuals. A single etiologic agent was identified in 381 patients, multiple agents were found in 331, and no agent was identified in 288. A high preponderance of aerobic bacteria was observed. Among the common pathogens were Staphylococcus aureus (324 patients, 45.51%), Pseudomonas aeruginosa (218 patients, 30.61%), Escherichia coli (54 patients, 10.67%), Staphylococcus epidermidis (32 patients, 4.49%), and Enterococcus faecalis (62 patients, 8.71%). In antibiotic sensitivity pattern it was observed that imipenem and tigecycline is the most sensitive in gram negative bacteria and vancomicyn and ciprofloxacin is the most sensitive to gram positive bacteria.
