Non-Fermenting Gram-Negative Isolates as Infecting Agents and Antibiotic Resistance: Three-Year Data

Objective: This study aimed to investigate clinical non-fermenting gram-negative isolates and antibiotic resistance profiles for three years in a tertiary hospital.Materials Methods: A total of 3817 strains isolated from various cultures between January 2017 December 2019 Balıkesir Atatürk City Hospital were investigated retrospectively. Identification susceptibilities performed using conventional methods PhoenixTM 100 system (Becton Dickinson, MA, USA).Results: 2201 (57.7%) P. aeruginosa, 1283 (33.6%) A. baumannii-calcoaceticus complex, 202 (5.3%) S. maltophilia 131 (3.4%) B. cepacia complex identified. The majority intensive care units (54.5%), followed by internal medicine (33.4%) surgical services (12.1%). All species showed over 70% most antibiotics. In addition β-lactam (generally 30%), fluoroquinolones (30.4%) seemed have particular importance. Co-trimoxazole below 10% isolates. ceftazidime increased (2018, 22.2%; 2019, 67.0%). Conclusion: issue cannot be won just developing novel antimicrobials, but also increasing the efficiency current ones. first step is “diagnose” condition, like local surveillance studies.
