Abstract

Objective: Study the antimicrobial resistance characteristic of Pseudomonas aeruginosa strains isolated from internal medicine wards of Military Hospital 103. Subject and methods: This cross-sectional study aimed to investigate the antimicrobial resistance features of P. aeruginosa strains isolated from internal medicine wards of Military Hospital 103 in 2020. Results: The total number of P. aeruginosa strains isolated in 2020 was 109. Of which, P. aeruginosa was mostly isolated from male patients (68.8%), who were >60 years old (51.4%), the internal medicine intensive care unit (32.1%), and infectious diseases department (22.0%). P. aeruginosa was the most resistant to levofloxacin (66.4%), ciprofloxacin (66.1%), and ticarcillin/clavulanic acid (62.4%). By contrast, P. aeruginosa was the least resistant to colistin (5.3%). P. aeruginosa was the most sensitive to amikacin (57.8%) and the least sensitive to levofloxacin (31.8%). Conclusion: Our study indicated that P. aeruginosa was mostly isolated from the internal medicine intensive care unit and patients >60 years old. P. aeruginosa was the most resistant to levofloxacin, ciprofoxacin, and ticarcillin/clavulanic and the least resistant to colistin. P. aeruginosa was the most sensitive to amikacin and the least resistant to levofloxacin.
