Acinetobacter baumannii has emerged as a highly troublesome pathogen for many institutions globally. As a consequence of its immense ability to acquire or upregulate antibiotic drug resistance determinants, it has justifiably been propelled to the forefront of scientific attention. The clinical specimens over a period of 3 years (January 2014 to December 2016) were analyzed and the A. baumannii isolates obtained by an automated identification system (Vitek 2 Compact) were segregated for further study. Their antibiograms were studied and a clinical correlation was made to assess their pathogenic status and mode of acquisi¬tion. Further, the nosocomial infections acquired during this period were studied and the contribution made by A. baumannii was calculated to assess its nosocomial status. Prevalence of A. baumannii was 7.72% from the entire hospital and 75.22% in intensive care unit. Maximum isolates were from respiratory secretions (52.08%) followed by blood (17.9%). Of all isolates 27.78% proved to be pathogenic. A. baumannii contributed to 69.18% ventilator associated pneumonia, 16.94% Catheter Associated Blood Stream Infections, 15.82% Surgical Site Infections and 10.95% Catheter Associated Urinary Tract Infections. Overall resistance of A. baumannii towards carbapenems was 88.5% from all hospital isolates. ICU isolates showed higher resistance (95.04%) as compared to Inpatient Department (79.87%) and Out-patient Department (80.0%). In this study, 27.78% of A. baumannii isolates showed a pathogenic potential in with high rate of carbapenem resistance. We must be cognizant of the fact that all A. baumannii isolates doesn’t necessarily mean infection and antibiotics should only be given in clinically proven infections.
