Abstract

Objective: Study the distribution and antimicrobial resistance characteristics of Pseudomonas spp. except Pseudomonas aeruginosa, which were isolated from patients at Military Hospital 103 from 2014 to 2022. Subject and methods: This was a descriptive study. The subject of the study was Pseudomonas spp. strains isolated from patients at Military Hospital 103 from 2014 to 2022. Results: A total of 58 strains of Pseudomonas spp. were isolated from 2014 to 2022. P. putida was the most common pathogenic species (63.8%). Pseudomonas spp. strains were mostly isolated from male patients (74.1%), patients ≥60 years old (43.8%), urine specimens (39.7%), and surgery departments (34.5%). Pseudomonas spp. had the highest sensitivity rate to Amikacin (64.8%), followed by Gentamycin (53.8%) and Tobramycin (52.0%). In contrast, the bacteria were the most resistant to antibiotics such as Trimethoprim/sulfamethoxazole (87.0%), Ticarcillin/clavulanic acid (78.7%), and Levofloxacin (72.0%). Conclusion: The study indicated that Pseudomonas spp. strains were mainly isolated from urine and specimens from respiratory tract. Pseudomonas putida was the most common bacterial species in the Pseudomonas genus except Pseudomonas aeruginosa. Pseudomonas spp. was the most resistant to Trimethoprim/sulfamethoxazole, Ticarcillin/clavulanic acid, and Levofloxacin and the most sensitive to Amikacin.
