Background: Klebsiella species are common causes of nosocomial, ulcers, blood and urinary tract infections, and also acquired pneumonia from the hospital and various intra-abdominal infections. Bacterial resistance mechanisms against antibiotics are different, but one of these resistance mechanisms, which is very problematic, is the production of β-lactamase enzymes in bacteria. The aim of this study was to determine the antibiotic resistance pattern and the presence of beta-lactamase genes in Klebsiella isolated from burn wounds among patients referred to Shahid Motahhari Hospital in Tehran.
Materials and methods: 100 strains collected for confirmation of production of broad-spectrum beta-lactamases (ESBLs) were tested by CDT (Combined Disk Test). Finally, β-lactamase genes were investigated using polymerase chain reaction.
Results: The highest resistance rate was observed to ampicillin (93%). 23% of isolates produced ESBLs. The highest frequency of genes was bla shv gene (26.8%).
Conclusion: The presence of beta-lactamase genes with high antibiotic resistance is very worrying. Since the present genes can spread through mobile genetic elements in bacteria, among bacteria, it is considered to be a serious alert in the treatment of infections caused by Klebsiella.
