The gram-negative bacteria Acinetobacter baumannii
is often a cause of nosocomial infections like; meningitis, bacteremia, pneumonia, and urinary tract infections. A. baumannii
is known as an emerging cause of nosocomial infections worldwide. Colistin is the last line treatment for multidrug-resistant A. baumannii
, and unfortunately, its resistance to colistin is being reported from all around the world.
Materials and Method: This prospective study was carried out during Jeb 2014 to Jan 2016 (2 years) on 100 A. baumannii samples isolated from Wound swabs, urine, respiratory secretions, and blood of patients admitted to the intensive care unit of IMS and SUM Hospital, Bhubaneswarm India. The bacteria were recognized through microscopy and biochemical tests. The disk diffusion method with colistin disk (Himedia, Mumbai, India) was utilized to identify the resistance to colistin.
Results: A total of 100 A. baumannii bacteria were identified, of which 93 were sensitive and 7 were resistant to colistin, respectively, according to the disk diffusion test
Conclusion: The results showed that the resistance of A. baumannii to colistin, as the last line treatment, is rising in Bhubaneswar, Odisha, India
