Purpose: Urinary tract infection (UTI) is one of the serious infections caused by the bacteria
Enterococci. Vancomycin-Resistant Enterococci (VRE) is a persevering clinical problem globally.
This study aims to detect high-level aminoglycoside and vancomycin resistance in uropathogenic
Methodology: A total of 75 clinically relevant Enterococcus spp. grown from urine samples, were
collected following convenience non-random sampling method. Identified by standard biochemical
tests and susceptibility to antibiotics was studied by Kirby Bauer’s disc diffusion method. The MIC
of vancomycin was detected by agar dilution test. Van A, and Van B genes in VREs were detected
Results: Among 75 Enterococcal isolates, 43 (57.3%) were E. faecalis, 12 (16%) were E. faecium,
6 (8%) of each were E. pseudoavium and E. casseliflavus, 5(6.66%) were E. dispar and 3 (4%)
were E. durans. E. faecalis (n=19) and E. faecium (n=3) were resistant to High Level Streptomycin
(HLS). E. faecalis (n=21) and E. faecium (n=6) were resistant to High Level Gentamicin (HLG). 4
(9.3%) E. faecalis were vancomycin-resistant, out of which 3 were of Van A, and one was both
Van A and Van B genotype.
Conclusion: Isolation of high level aminoglycoside resistant (HLAR) Enterococci is a challenge
for the treating physician because aminoglycoside cannot be used in combination with glycopeptide
or ampicillin for such isolates. The occurrence of HLAR, Van A, and Van B VRE genotypes is
a cause of concern as they may transfer drug resistance genes to other bacterial isolates, thus leading
to limited therapeutic options.
