Resumo
The 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.
