Abstract

From 2019 to 2022, 734 Pseudomonas aeruginosa strains isolated at Hanoi Medical University Hospital were identified and their antibiotic resistance profile were determined by Vitek2 compact system. The presence of five common carbapenemase-encoding genes (blaKPC, blaNDM, blaVIM, blaIMP, blaOXA-48) was investigated by PCR in 143 carbapenem-resistant strains. The results indicated moderate sensitivity (40 - 70%) of P. aeruginosa strains to the tested antibiotics. Among carbapenem-resistant strains, 71% carried genes encoding class B carbapenemases (blaNDM, blaIMP). Notably, piperacillin/tazobactam and amikacin demonstrated high efficacy against carbapenem-resistant strains. These findings support clinicians in selecting empirical antibiotic therapy for infections causing by P. aeruginosa prior to obtaining antibiotic susceptibility results.
