Current trend of nonfermenting gram negative bacilli in a tertiary care hospital in Trivandrum

Abstract

Non fermenting gram negative bacilli initially thought to be contaminants and commensal are now an important pathogens. They frequently exhibit multi drug resistance and harbour multidrug resistant gene of the present study was to characterize the prevalence of NFGNB along with their antimicrobial sensitivity pattern among the patients coming to our hospital a tertiary care center. This study has been conducted in the Department of Microbiology at a tertiary care teaching hospital over a period of 6 months from June to November 2015. NFGNB were isolated and identified from clinical specimens by standard procedure and antibiotic sensitivity test was performed. Prevalance rate of NFGNB was found to be 4.9%. Pseudomonas aeruginosa was the most common isolate at 57.7% followed by Acinetobacter baumanii at 26.8%. Imipenem and Meropenem were found to be most sensitive followed by Piperacillin tazobactum. First and second generation drugs showed high level of resistance.
