PERFIL DE SENSIBILIDADE MICROBIANA IN VITRO DE LINHAGENS PATOGêNICAS DE Escherichia coli ISOLADAS DE CARNE BOVINA

This study aimed to analyze the antimicrobial resistance of Escherichia coli strains (EPEC A, EPEC B, EPEC C, EIEC A e EIEC B) isolated from bovine meat. The antimicrobial susceptibility test was evaluated using the technique described by the National Committee for Clinical Laboratory Standards. The strains were resistant to most antibiotics tested, and gentamicin showed the best efficiency, with 84.9% of the strains showing sensitivity. In addition, cefoxitin was the least effective antimicrobial agent, have a higher percentage of resistant strains. The multidrug resistance to antimicrobials is a finding of great importance to public health, as resistant pathogens may be conveyed to consumers by the ingestion of animal products, making difficult the treatment of bacterial infections and increasing the occurrence of bacteria resistant to antibiotics.
