Effect of active immunization with Stx2 toxoid on E. coli O157:H7 colonization levels. Mice were vaccinated with Stx2 toxoid (▲) or mock-vaccinated with PBS (■). Colonization was monitored daily following infection for the first 21 days, then every other day through day 35, and then weekly through day 63 post-infection. Colonization was determined by enumeration of the CFU shed/g feces and is reported for each animal (n=10–11/group). The lines represent the GM for the vaccinated (gray) and the mock-vaccinated (black) group. The limit of detection was 102 CFU/g feces (marked by an arrow).
