The aim of this study was to determine the incidence
of vancomycin-resistant enterococci (VRE) in tap and artesian well waters and
to detect the vancomycin resistance genes and virulence genes of the isolates
obtained from the samples. For this purpose, 200 samples (119 tap and 81
artesian well waters) were collected from several water supplies during
November 2013 and June 2015 period in Bursa province. Seven isolates were
recovered from artesian well waters and confirmed as Enterococcus by PCR method. E-test
performed for vancomycin and teicoplanin MIC values indicated that only two
isolates had the intermediate-level (8
μg/mL) resistance to vancomycin.
No resistance was observed to teicoplanin in any of these isolates by E-test. All of 7 isolates were tested
for vancomycin resistance genes (vanA,
vanB and vanC) and virulence genes (gelE,
agg, esp and ace). The results showed that enterococci isolates had no these
genes. The present study suggested that the presence of the intermediate level
VRE in artesian well waters and, also the waters from environmental supplies
near human and animal niches could be play a role as potential reservoirs for
enterococci having several types of resistance to vancomycin. Also, vancomycin
resistant strains can be possible the spread in environment and also the
transmission to human and animals through contaminated water sources.
