Abstrakt: Background: Non-fermenting Gram-negative bacilli (NFGNB) were initially considered non-pathogenic contaminants but now have emerged as major pathogens because of increased isolation from clinical samples and emerging resistance to common antibacterial agents. Objectives: The study aims to determine the magnitude of NFGNB in clinical samples received at the Department of Microbiology, Nil Ratan Sircar Medical College, Kolkata, for a period of one year. Material and Methods: The samples were processed according to standard procedures; for identification and antibiotic susceptibility test, Vitek 2 Compact (Biomerieux©) was used. Results: Out of 725 bacterial isolates, 169 (23.31%) NFGNB were identified during the entire study period. Pseudomonas spp. (n = 84) was isolated most frequently, followed by Acinetobacter spp. (n = 73), Burkholderia cepacia (n = 7), and Stenotrophomonas maltophilia (n = 5). Both Pseudomonas spp. and Acinetobacter spp. showed greater susceptibility to piperacillin-tazobactam and poor susceptibility against cefepime. Conclusion: It is necessary to identify these drug resistant pathogens in healthcare setup. The antibiotic susceptibility pattern of these pathogens needs to be monitored to guide clinicians in better patient care and management by initiating proper antibiotic therapy.
