SANTO, Edilene; RODOLPHO, Daniela and MARIN, José Moacir. Presence of extraintestinal pathogenic Escherichia coli in butcheries in Taquaritinga, SP, Brazil. Braz. J. Microbiol. [online]. 2007, vol.38, n.4, pp. 591-593. ISSN 1678-4405. http://dx.doi.org/10.1590/S1517-83822007000400002.
The study was conducted in twenty-three butcheries in the city of Taquaritinga, State of São Paulo, Brazil, surveyed during a 10 months period. Among two hundred and eighty-seven Escherichia coli strains isolated from samples of ground beef, meat-grinding-machines and the hands of manipulators, five were recognized as extraintestinal pathogenic E. coli (ExPEC), showing virulence factors (P and S fimbriae, hemolysin and aerobactin) and presenting multidrug resistance. Retail-sold food may constitute an important vehicle for the dissemination of ExPEC in communities, giving rise to reasons for concern.
