Bacteriological Profile of Burn Patients and Antimicrobial Susceptibility Pattern of their Wound Isolates at Nepal Cleft and Burn Center

Abstract

Background: Burn infections are the major causes of morbidity and mortality in burn patients. The infectious agent could be both Gram positive and Gram negative bacteria. The aim of this research was to study the bacteriological profile of burn patients and anti-microbial susceptibility pattern of their wound isolates.
 Methods: This cross-sectional study was conducted in Kirtipur Hospital, Nepal from January 1st to March 31st 2019. A total of 109 burn patients were included and their wound swabs were collected at the time of admission. All isolates were identified by standardized microbiological procedures. Anti-microbial susceptibility tests were performed by Kirby Bauer disc diffusion method.
 Results: Of 109 burn wound samples, 56 (59%) yielded culture growth and the Gram negative isolates were more common than Gram positives (77% vs. 23%). The most common organism isolated was Klebsiella spp. (25%) followed by Acinetobacter spp. (21%) and Staphylococcus aureus (18%). Most burn wound isolates were of resistant strain. Particularly, highly resistant strain of Acinetobacter spp. were isolated, most of which were sensitive to Tigecycline, Polymyxin B and Colistin only.
 Conclusion : Gram negative isolates were common in burn wound isolates and the antibiotic susceptibility pattern was different for different organisms. The use of antimicrobials should be judicious to further not escalate the problem of antimicrobial resistance in the healthcare settings.

Detection of Bacteria Causing Burn Infection Isolated from Several Hospitals in Baghdad

“…The antibiotic sensitivity test using the Vitek2 Compact System showed that the resistance rate was recorded in Staphylococcus aureus against Amikacin by 13 isolates, with a rate of 86.6%, and in Acinetobacter baumannii, towards Ceftazidime and Piperacillin antibiotics by 12 isolates at a rate of 100%, and Pseudomonas aeruginosa towards Colistin and Tobramycin at a rate of 6 isolates at a rate of 60%, and Klebsiella pneumoniae towards Colistin and Tobramycin at a rate of 8 isolates at a rate of 100% and Escherichia coli against Amikacin, Colistin and Imipenem with 7 isolates and 100%, and Proteus mirabilis against Colistin and Tobramycin with 6 isolates and 100%, and Burkholderia cepacia against 8 antibiotics with a rate of 100%. These results are in agreement with many studies [27,28]. Burn wound infection remains a serious problem for burn patients as many bacteria develop varying degrees of resistance to most known antibiotics.…”
