Abstract
It was studied whether vancomycin-resistant enterococci (VRE) colonize poultry raised without receiving antimicrobial growth promoters (AGP), in non-intensive production systems. A total of 200 cloacal swabs were colleted in farms (n=40) of eight different regions of the Distrito Federal. After selective isolation, the typical enterococcal colonies were submitted to the multiplex PCR to identify enterococcal species (E. faecalis, E. faecium, E. gallinarum, and E. casseliflavus), and genes coding for high-level vancomycin resistance phenotypes. No VRE were found in the examined samples. The prevalence rates were higher for E. gallinarum (n=26; 13.0%) and E. casseliflavus (n=11; 5.5%). It was found remarkable differences in the prevalence of E. gallinarum and E. casseliflavus among the poultry farms and studied regions, and it seems that poultry raised in non-intensive production systems in the Distrito Federal of Brazil are not reservoirs of VRE.
