| Aims: Pseudomonas aeruginosa is one of the major causes of nosocomial infections. This study aimed at investigating the antibacterial susceptibility and the prevalence of virulence and resistance genes of P. from patients in Tehran, Iran. Materials & Methods: In this cross-sectional study, 70 P. from infection and cystic fibrosis patients from and Pediatric Medical Center, Tehran, Iran during 2017-2018. Antibacterial susceptibility against eleven antibiotics was determined based on Isolates were, then, screened for the presence of virulence and resistance genes by Polymerase Chain Reaction (PCR). Findings: The highest and lowest antibacterial resistance rates were against ampicillin and respectively. The and genes were present in all P. . The prevalence of and genes in P. from a total of 18 CF patients was 66.6%, 66.6%, 22.2%, 72.2%, and 77.7%; and in a total of 52 burn patients was 84.7%, 100%, 28.8%, 73.07%, and 64.46%, respectively. VEB, PER, TEM, SHV, and CTX-M genes were found in 0.0%, 0.0%, 11.1%, 16.6%, and 5.5% P. from CF patients; and in 0.0%, 1 1.9%, 50 96.1%, 88.4%, and 40.3%, P. from burn patients, respectively. Conclusion: Generally, selective pressure caused by extensive use of antibiotics can be conducive to the selection of MDR bacteria. Therefore, choosing based on precise tests can prevent the increase of resistance in bacteria. | ||
