Cattle carriage of EHEC after challenge. The rectoanal junction (RAJ) mucosas of 10 Holstein steers were dosed with a single application of 109 CFU of either wild-type or yenI+ EHEC. The challenge strains were cultured from RAJ mucosal swabs on the indicated postchallenge days. (A) Mean log CFU of wild-type or yenI+ strain per swab from cattle throughout the experiment. (B) Percentage of animals (inoculated with either wild-type or yenI+ strain) culture positive with EHEC postchallenge throughout the period of 56 days.
