In chicken husbandry, antimicrobial resistance among enterococci has been observed. Glycopeptides and gentamicin MinimumInhibitory Concentrations in fecal poultry enterococci were determined. Glycopeptide and high-level gentamicin resistance(HLGR) genes were investigated. E. faecalis (n = 105) and E. faecium (n = 70) were the predominant species. In E. faecalis, HLGR(19%) was observed. In high-level gentamicin resistant E. faecalis, presence of aac (6´) -Ie-aph (2´´)-Ia gene was confirmed. VanA E.faecium (7.1%) were found, with HLGR (20%) and high-level streptomycin resistance (40%). vanA genotype was detected inglycopeptide resistant E. faecium (100%). These results highlight the presence of horizontally transferable antimicrobialresistance determinants in E. faecalis and E. faecium recovered from poultry. Existence of enterococcal reservoirs in poultry shouldbe taken into account as a potential source of antimicrobial resistance genes, strengthening their potential spread to humansthrough the food chain of horizontal transferable resistance determinants.
