Identification of pathogenic bacteria isolated from wound infections, and effect of some antibiotics

Abstract

In clinical practice, where empiric treatment of infections is common, wound infections are still a problem. Purpose: In this study, it was aimed to identification of pathogenic bacteria isolated from wound infections, and Effect of some antibiotics at Wasit, Iraq. Methods: Records of 102 patients' wound swabs taken with a suspicion of wound infections. Swabs from the wounds were used to inoculate and culture smears. Gram-stained bacterial colonies were studied under a microscope. To determine the types of pathogens, biochemical tests were conducted. For evaluating antibiotics, the Kirby-Bauer disk diffusion method was employed. Results: Infections in wounds were prevalent 81.4% (CI: 60.869).83 infected wounds yielded a total of 10 distinct species. Staphylococcus aureus (26.5%)was the most prevalent bacterial species found, followed by Pseudomonas aeruginosa(14.4%), Proteus mirabilis (12%), Escherichia coli (10.8%), and Enterobacter cloacae (8.4%). Two species made up the majority of the 25 (30.1%) polymicrobial infections that were discovered in the samples. The P. aeruginosa and P. mirabilis relationship was the most frequent. The studied antibiotic resistance levels among the bacterial isolates varied (8.3% to 100%) resistance. Amoxicillin-clavulanate resistance was present in all isolates.Age and sex had no bearing on the prevalence, type of agent, and pattern of antimicrobial resistance.
