Resistência a drogas em amostras de Escherichia Coli isoladas de aves em Londrina - PR.

Abstract

Twenty nine strains of Escherichia coli isolated from chicken in Londrina, were tested for drugs resistance and distribution ofR plasmids. It was determinated the resistence level of strains and 93,1% were resistant, 79,3% were multiple antibiotic resistance. Most was resistance to tetracycline and sulphadiazine (79,3% and 68,1% respectively). The resistance to chloranphenicol, ampicilin an kanamycin was lower. In genetic studies of transferance of resistant determinant by conjugation, it was revealed 33,3% of conjugative R plasmids. These results would present a serious public health hazard whereas the antibiotic resistant E. coli, carrying R plasmids, reach man by animals feed.
