Profile of microorganisms isolated from blood and wound in the first week of post burn infections and antibacterial resistance pattern

Abstract

Infection of burn wounds is a serious problem leading to death and need critical care.The purpose of this study is to identify common microorganisms isolated from blood and wound in the first week of post burn infections and assess their susceptibility to the commonly used antibacterial agents.Blood and wound swabs from 62 patients with burn wound infections were collected on Third and Sixth day of post burn infections.The microorganisms were isolated and identified by standard microbiological methods. Susceptibility test were performed by Kirby–Bauer disk diffusion method. Out of 62 patients, female (62.9%) were found to be affected more than males (37.1%) while (53.2%) of the patients were paediatric and the remaining (46.8%)were adults. The flame burn was the predominant cause of burn among patients; (51.6%) had flame burns, (33.9%) a scald, and (14.5%) had an electrical burn.It was found that predominant aerobic and anaerobic bacteria were Pseudomonas aeruginosa (15.3%)and Bacteroides spp.(4.8%), respectively. While Candida tropicalis (0.8%) was the most common fungal organi followed by Candida albicans (0.4%). In most of the cases, the same microorganisms were found in blood and pus samples. All the bacterial isolates showed high resistance to used antibiotics.Imipenem was the most effective antibiotic followed by Meropenem and Ceftriaxone.
