Vancomycin-Resistant Enterococci from Humans and Retail Chickens in Taiwan with Unique VanB Phenotype- <i>vanA</i> Genotype Incongruence

Abstract

Vancomycin resistant enterococci (VRE) with VanB phenotype-vanA genotype incongruence were found in all 39 VRE isolated from chicken carcasses and four human VRE isolates in Taiwan. Three identical mutations in the vanS gene were found in the VanB phenotype-vanA genotype VRE sequenced. This finding indicates possible transmission of glycopeptide resistance among different hosts.
