Antibiotic susceptibility pattern of Pseudomonas aeruginosa isolates, collected from patients in Tabriz hospitals.

Background and Aim : Pseudomonas aeruginosa is an opportunistic pathogen that is a leading cause of morbidity and mortality in patients and immunocompromised individuals. Eradication of P. aeruginosa has become increasingly difficult due to its remarkable capacity to resist antibiotics. The pattern of Pseudomonas aeruginosa antibiotic susceptibility varies geographically, and Antibiotic susceptibility testing should be performed to select the correct antimicrobial treatment. The aim of this study was to determine the pattern of antibiotic resistance in Pseudomonas aeruginosa strains isolated from patients in Tabriz Methods : A total of ۷۸ Pseudomonas aeruginosa isolates, collected from Sina, Madani and Emam Reza Hospitals in Tabriz. To determine the pattern of antibiotic susceptibility by disk diffusion method using discs, common used antibiotics in hospitals were examinedResults : In this study the most effective antibiotics against isolates were amikacin and colistin with ۹۵% susceptibility whereas the highest resistance was to Amoxicillin and Co-trimoxazole and with ۹۲% and ۹۱%Conclusion : Continuous monitoring of antibiotic susceptibility pattern of Pseudomonas aeruginosa is essential and rational treatment regimens prescription by the clinicians is required to limit the spread of antimicrobial resistance.
