Abstract

The aim of this study was to determine the antimicrobial resistance of 176 Escherichia coli strains isolated from broiler chicken organs. The strains were challenged with beta-lactam, quinolones and fluoroquinolones, observing resistance to beta-lactam antibiotics (97.7%) and quinolones (86.7%). The results showed that 71.6% of the isolates phenotypically expressed the production of extended spectrum beta-lactamases (ESLB). By PCR, resistance genes for beta-lactams blaTEM, blaSHV, blaCTX-M1 and Amp-C and resistance genes for quinolones qnrA, qnrB, qnrS were determined. The genes Amp-C (74%), blaCTX-M (65%), blaSHV (65%), blaTEM (50%), qnrB (86.4%) and qnrS (11.9%) were found. The qnrA gene was not evident in the samples analysed. The results obtained revealed a large percentage of resistance to the studied antibiotics and the presence of resistance genes in isolates from poultry for human consumption, which constitutes a risk for Public Health.
