Abstract
Background: The gram-negative bacteria Acinetobacter baumannii is often a causative organism of nosocomial infections like meningitis, bacteremia, pneumonia, and urinary tract infections. A. Baumannii is an emerging agent of nosocomial infections worldwide. Colistin is the ultimate anti-microbial agent for the treatment of multidrug-resistant A. Baumannii, and in recent times, colistin-resistance is being suggested from all around the world. Materials and Method: This prospective observational study was carried out between January 2014-Jan 2016 (Study period: 2 years) on one hundred A. Baumannii samples removed from bed-sore swabs, urine, respiratory secretions, and blood of patients admitted to the intensive care unit of IMS and SUM Hospital, Bhubaneswar, Odisha, India. The micro-organisms were identified through microscopy and biochemical tests. The disk diffusion method with colistin disk (Himedia, Mumbai, India) was utilized to discover the resistance to colistin. Results: A total of hundred A. Baumannii micro-organisms have been identified, of which 93 had been sensitive and seven with proof of colistin-resistance, consistent with the disk diffusion test. Conclusion: The outcomes confirmed the presence of resistance of A. Baumannii to colistin, in Neuro-ICU set-up in a Tertiary care centre in Bhubaneshwar, Odisha.
