  1. E. coli isolates from Farms 1 to 5. Pathotypes and virotypes are described. At Farms 1 to 4, the pathotype Enterotoxigenic E. coli (ETEC) was found. At Farm 5, Shiga-toxigenic E. coli (STEC) was present. At Farms 1 to 5, the predominant virotypes detected by multiplex PCR analysis were STa:F5:F41, STb, F18, LT:STb:F4 and Stx2e:F18, respectively
