Infection is the leading cause of morbidity and mortality among burn patients and is accentuated multifold by the emergence of antimicrobial resistance among the nosocomial isolates. It is vital to know the common organisms involved in infected burn wound etiology and their respective antibiotic susceptibility patterns. These crucial findings can help in formulating a better and more efficient antimicrobial therapy plan for controlling burn wound infections. The current study was conducted to identify the common bacteria involved in causing infections in wounds of burn patients and their respective antibiotic susceptibility patterns in three hospitals of Abbottabad, Pakistan. A total of 100 patients were included from the burn units of three hospitals in Abbottabad. Wound swabs were taken from the deepest portions of infected burns, and the organisms involved were isolated via standard microbiological techniques. The Kirby-Bauer disc diffusion technique was used to monitor antibiotic susceptibility. Gram-positive organisms were found readily in infected burn wounds. Staphylococcus aureus (46%) was the most common isolate followed by Staphylococcus epidermidis (17%), Escherichia coli (16%), Proteus spp. (12%), Klebsiella pneumoniae (10%), and Pseudomonas aeruginosa, which was only 7%. Gram-positive bacteria were sensitive to amikacin, gentamicin, cefotaxime, and norfloxacin. In contrast, the gram-negative isolates were sensitive to amikacin, chloramphenicol, and nalidixic acid. Pseudomonas was resistant to most of the antibiotics tested in the present study. [ABSTRACT FROM AUTHOR] |
