Abstract :

Objective Klebsiella pneumoniae is one of most opportunistic pathogens that can be related to nosocomial infections. Increased acquisitions of multidrug resistance in this bacterium as well as the transfer of genes to other strains have caused concern. Integrons play key role in the acquisition and the spread of resistance genes. The aim of this study was evaluated the frequency of resistance genes sulI, sulII, tetA, tetB, class I (intI gene), class II integrons (intII gene) and the association between multidrug resistance and the presence of integrons in K. pneumoniae. Results Antibiotics susceptibility test was performed on 126 of K. pneumoniae isolates. Also, DNA extraction was done and genes were detected using PCR method. In this study, 67 isolates (53%), carrying both the sulI and sulII genes. Forty-five percent tetracycline-resistant isolates were tetA or tetB positive. The prevalence of intI gene was 96%, while only sixteen isolate harboring intII gene (12.5%). Our results showed the high prevalence of integrons in MDR K. pneumoniae, indicating the important role of these genes in the transmission of antibiotic resistance. Keywords: Mobile genetic elements, Multidrug-resistance, K. pneumoniae
