Abstract :

Introduction: Multidrug resistant nosocomial infections are one of the leading cause of morbidity and mortality in intensive care units (ICUs) accounting a major burden on patient and public health system. Objectives: Present study was done to identify prevalence of predominantly isolated bacterial organisms and their drug resistance pattern in ICUs. Material & Method: A total of 183 samples received from various ICUs were processed and antibiotic susceptibility testing was performed as per CLSI recommendations. Results: A total of 89(48.63%) of 183 samples were culture positive out of which Citrobacter spp.(22.47%) was most frequently isolated bacteria followed by Klebsiella spp.(16.85%), Escherichia coli (16.85%), Pseudomonas aeruginosa (15.73%),and Acinetobacter spp (11.23%). Citrobacter spp was found to be emerging multidrug resistant organism. Most of the isolates are multidrug resistant to the third generation cephalosporins, and quinolones antibiotics. Conclusion: Regular surveillance of resident microbial flora and antibiotic susceptibility patterns is very important in implementing therapeutic strategies to reduce emergence of drug resistance strains in ICUs.
