IDENTIFICATION AND ANTIMICROBIAL SUSCEPTIBILITY PATTERN OF ENTEROBACTER SPECIES BY VITEK-2 SYSTEM ISOLATED FROM VARIOUS CLINICAL SPECIMEN IN GOVT MEDICAL COLLEGE KOTA (RAJASTHAN)

Background: Enterobacter were proposed as a genus in 1960 by Hormaeche and Edwards based on the division of the former genus Aerobacter into motile, ornithine decarboxylase (ODC)–positive strains (Enterobacter) and nonmotile ODC-negative strains (Klebsiella). The Vitek-2 system is the second generation of Vitek and offers a more sophisticated model of data analysis as well as a fully automated process for card identication, organism suspension dilution and card lling. To study Aim and Objectives: identication and antimicrobial susceptibility pattern of Enterobacter species by Vitek-2 system isolated from various clinical samples. Material and Methods: A total of 100 Enterobacter species obtained from various clinical samples like urine, pus, sputum, endotracheal aspirate and bodyuids (pleural, ascitic, peritoneal and CSF) etc. of patients received at Department of Microbiology, Government Medical College & Associated Group of Hospitals, Kota during a period of approximately 1 year from May 2021 to May 2022 were taken for the identication and Antibiotic sensitivity testing by Vitek-2 system. Out of 100 Enterobacter isolates, 69% w Result: ere E.cloacae and 31% were E.aerogenes. Antimicrobial susceptibility results of Enterobacter species revealed the susceptibility of 56.41% for Nitrofurantoin, 69% for Piperacillin/ Tazobactam and 72% for Cefoperazone/ salbactam. Enterobacter seems to be emerged with increasi Conclusion: ng resistance to multiple antibiotics.
