ANTIMICROBIAL SUSCEPTIBILITY PATTERN OF ENTEROCOCCUS SPECIES ISOLATED FROM URINE SAMPLES FROM A TERTIARY CARE HOSPITAL

Agrawal Neha, Goyal Lokendra, Bachhiwal Rekha

Abstract


Enterococcus species have emerged as very important pathogens causing urinary tract infections and multi drug resistance among Enterococci further add to the problem. A total of 105 Enterococci were isolated from urine samples. Speciation was done according to Facklams and Collins conventional method. Antimicrobial susceptibility pattern was determined by Kirby Bauer disc diffusion method. Among 105 Enterococcal isolates, E. faecium was predominant species 71(67.62%) over E. faecalis 34(32.38%). There was alarmingly high resistance to commonly used antimicrobial agents including quinolones (88-93%), ampicillin(71.4%) and high level gentamicin(62.8%). E. faecium was found to be more resistant than E. faecalis (p <0.05).Considering increasing isolation of multi drug resistant Enterococci from urine samples there is a need to carry-out regular surveillance of antimicrobial resistance of Enterococci to recommend appropriate therapy.
