Abstract

The Brazilian poultry industry highlights by high productivity and competitiveness of its products on the world market. For several decades the use of antibiotic was employed as additives in feed for the purpose of improving animal performance. However, these additives may exert a selective pressure on bacteria, changing the kinetics of acquiring antimicrobial resistance, especially when this resistance is encoded by mobile DNA elements, such as plasmids and integrons. The ban on the use of these drugs by some countries reinforces the popular pressure for organic products. This study aims to compare the antimicrobial resistance in Escherichia coli strains isolated from broilers raised in conventional and organic systems. We will be used 200 fecal samples and 160 meat samples from conventional and organic farms, for isolation and identification of E. coli. The strains will be subjected to phenotypic and molecular characterization of antimicrobial resistance determinants (AU)
