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

ABSTRACT

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 identification, organism suspension dilution and card filling. To study Aim and Objectives: identification 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 fiuids (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 identification 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.
