The occurrence of vancomycin resistant enterococci (VRE) was investigated in feces of poultry, pigeons, deers and rats. Feces samples were collected from 25 broilers growing in poultry production farms that never used in the diets avaporcine as growth promoter, 6 broiler from different poultry production farms that used regularly avaporcine in the formulated diets until 1997, 8 deers from natural reservoirs, 15 pigeons, and 20 rats arrested from field conditions. The samples of Enterococcus gallinarum isolated from poultry feces were resistant to vancomycin independently of the use of avaporcine in the formulated diet.
