Caracterização fenotípica pelo antibiograma de cepas de Escherichia coli isoladas de manipuladores, de leite cru e de queijo. Ciência Rural, Santa Maria, v. 36, n.4, p. 1221-1227, 2006.0103-8478e- 1678-4596http://repositorio.bc.ufg.br/handle/ri/15529The present work aimed to type E. coli strains obtained from handlers hands and noses, raw milk and Minas Frescal cheese produced by a dairy milk processing plant in Goiás, Brazil in order to establish a contamination relationship between the sources of E. coli and cheese. Twenty-four samples were collected from raw milk and Minas Frescal cheese, 46 from hands and 46 from noses of handlers involved in the cheese manufacturing, between March/2004 and February/ 2005. All 69 E. coli strains isolated were submitted to the susceptibility test for six antimicrobials (ampicillin, cephalothin, ciprofloxacin, gentamicin, trimethopim-sulphamethoxazole and tetracycline. The strains were grouped in 17 different phenotypic susceptibility profiles (A-Q). The test allowed to establish correlation among a cheese strain (14Q b ) and a handler (10M 1 ) strain that presented the same susceptibility profile (E) suggesting a possible product contamination during the handling. In conclusion, the phenotypic susceptibility profiles determinated by the antibiogram method failed to establish a correlation between the strains obtained from the probable sources (handlers and milk) and the final products.porAcesso AbertoColiformesLeite cruManipulaçãoQueijo Minas FrescalColiforms,Minas Frescal cheeseHandlingRaw milk,Artigo10.1590/S0103-84782006000400027
