Abstract Purpose This study analyzed antibiotic resistance mechanisms and molecular epidemiology of multidrug-resistant Pseudomonas aeruginosa (MDR-PA), aiming at providing clues for prevention and control of MDR-PA infections. Methods The carbapenemase resistance genes (VIM, IMP, NDM, KPC, GES, OXA-40) of MDR-PA strains were detected by polymerase chain reaction (PCR) and sequencing. The efflux pump system (MexA, MexC, MexE, MexX), AmpC and OprD2 were detected by real-time fluorescent quantitative PCR (qPCR) in MDR-PA group and sensitive-Pseudomonas aeruginosa (S-PA) group. The homology analysis of MDR-PA strains was performed by multilocus sequence typing (MLST). Results A total of 81 MDR-PA strains were collected from the First Affiliated Hospital of Guangxi Medical University from October 2022 to October 2023. Among the carbapenemase detected, the detection rate of NDM-1 was the highest, with a rate of 34.57% (28/81). MexA had a higher expression in MDR-PA group than that in S-PA group (P |
