The effect of the pO157 on survival of E. coli O157:H7 in cattle following oral administration of the bacteria. Four steers were given a single oral dose of 1.0 × 1010 CFU containing both Sakai and Sakai-Cu. RAMS samples were cultured by direct plating onto SMAC-CTVM and sorbitol-negative MUG-negative colonies were confirmed to be the O157 serotype by latex agglutination. Isolates from each sample were sub-cultured and differentiated as Sakai or Sakai-Cu by PCR. Line height on each day represents the average number of total E. coli O157:H7 recovered from the steers expressed as log CFU/swab. Bar height represents the average percentage of Sakai-Cu in the total number of E. coli O157.
