Abstract – Escherichia coli O157:H7 is an important human foodborne pathogen being cattle the main reservoir. Recent studies have indicated that sheep are also potential carriers. The aim of this study was to detect the presence of E. coli O157:H7 and associated virulence factors in feces of grazing lambs intended for slaughter in Uruguay. Individual fecal samples were collected from grazing lambs (n=220) in four research units of the National Institute of Agricultural Research (INIA) and sent refrigerated to the microbiology unit of the Technological Laboratory of Uruguay (LATU).
Samples were analyzed for the presence of E. coli O157:H7 and genes encoding virulence factors (eae, stx1, stx2) following standard procedures. Samples positives for E. coli O157:H7 were identified in two of the four research units participating in the study. Overall, 9 of 220 (4.1%) fecal samples were E. coli O157:H7-positive. All isolates carried genes encoding intimin and Shiga toxins 1 and 2. This study revealed the presence of pathogenic E. coli
O157:H7 in the feces of grazing lambs ready for slaughter in Uruguay. It suggests that feces can be a source of contamination of lamb carcasses
with E. coli O157:H7.
