RESISTÊNCIA ANTIMICROBIANA EM CEPAS DE Escherichia coli ISOLADAS DE CARNE DE SOL COMERCIALIZADA NO MUNICÍPIO DE TEÓFILO OTONI, MINAS GERAIS

Abstract

Sun-dried meat is considered a typical product of the north and northeast region of Minas Gerais, whose elaboration is based on regional concepts and norms, often favoring the occurrence of microorganisms in this type of food. In this sense, the present work aimed to evaluate the microbiological quality of sun-dried meat sold in the city of Teófilo Otoni, Minas Gerais, as well as to measure the resistance profile of isolated strains of Escherichia coli against different antimicrobials. E. coli was found in 13.85% (23) of the samples acquired from a total of 15 butcher shops in the municipality. Sixty-one strains from positive plaques of 166 dried meat samples were analyzed. Of these, 27.86% (17) were confirmed for E. coli. The resistance of the isolates was tested using the disk-diffusion test and the MIC Test Strip. Of the 17 strains tested in the antibiogram, 58.82% (10) were resistant to at least one antimicrobial, with 17.64% (3) being multiresistant. The results obtained suggest contamination of sun-dried meats in the study, due to the presence of E. coli in different samples, and it was also observed that more than one antimicrobial was ineffective against this bacterium.
