Abstract

Introduction: Non‑fermenting gram negative bacilli (NFGNB) have emerged as an important health care associated pathogens especially in immune compromised patients. Characterization of NFGNB, the infections, the risk factors associated and study of their antibiogram is important in the management of infections. The aim of the present study was to characterize the NFGNB and to assess the risk factors and the antibiotic susceptibility pattern among the non fermenters. Materials and Methods: A total of 800 isolates of non fermenters from various clinical samples were identified. Antimicrobial susceptibility testing was performed by Kirby Bauer disc diffusion method. The relevant patient data were collected from the patient records. Results: Among 800 NFGNB, Pseudomonas species (59%) and Acinetobacterspecies (28%) were the prevalent pathogens. Levels of resistance to Imipenem, Meropenem were 16%, 12%for Pseudomonas spp., 43%, 62% for Acinetobacter spp. An association of Pseudomonas infection with type II diabetes was significant. Acinetobacter spp. Mostly isolated from patients with aspiration pneumonia and ventilator associated pneumonia. Conclusion: NFGNB are emerging as major nosocomial pathogens. Antibiotic susceptibility testing is necessary as carbapenem resistance is on rise.
