Abstract Background Resistance to carbapenem, the last line of treatment for gram-negative bacterial infections has been increasing globally and becoming a public health threat. Since integrons may aid in the transmission of resistance genes, the purpose of this study was to detect the frequency of class 1, 2, and 3 integrons as well as carbapenem-resistant genes in clinical isolates of P. aeruginosa that are resistant to carbapenem. Methods This study was carried out on 97 clinical isolates of P. aeruginosa isolated from wound and urine samples. The antimicrobial susceptibility for all isolates was tested by the disc diffusion method. The presence of integrons and carbapenem-resistant genes among carbapenem-resistant P. aeruginosa isolates was evaluated by conventional PCR. Results The antimicrobial resistance rate among P. aeruginosa clinical isolates was high, with imipenem resistance in 58.8% of the studied isolates. In this study, 86% of the carbapenem-resistant P. aeruginosa isolates carry carbapenemase genes, with bla VIM being the most common gene followed by the bla OXA−48 gene. Class 1 and class 2 integrons were reported in 37 (64.9%) and 10 (17.5%) of the tested carbapenem-resistant P. aeruginosa isolates, respectively. Conclusion Our data reported a high prevalence of class 1 integrons in carbapenem-resistant P. aeruginosa clinical isolates, suggesting the important role of integrons in carbapenem-resistant gene transfer among such isolates. |
