Description:
A survey was conducted to determine the occurrence of vancomycin resistant enterococci (VRE) in animal and human fecal samples. Fecal samples from 14 animal species and humans were analyzed by quantitative culture for enterococci and VRE. Over 800 VRE isolates were characterized by biochemical reactions. Representative isolates from each host species were analyzed for the vancomycin resistant genes van A, van B, van C-1, C-2. Minimum inhibitory concentrations for vancomycin and teicoplanin were also determined. None of the isolates exhibited high level vancomycin resistance. Every host species however, carried enterococci which exhibited intrinsic intermediate resistance to vancomycin and sensitivity to teicoplanin.
