Impact of passively administered anti-Stx2 neutralizing antibodies on E. coli O157:H7 strain 86-24 colonization level. Mice received polyclonal rabbit anti-Stx2 serum (▲) or NRS (■) twice by IP administration prior to infection. Colonization was monitored following infection, twice daily for the first 4 days, and then once daily through day 7. Colonization was determined by enumerating the CFU shed/g feces and is reported for each animal (n=5). The dashed lines represent the GM for the anti-Stx2 (gray) and the NRS (black) treatment groups. Asterisks indicate specific days when statistically different colonization levels were observed. The limit of detection was 102 CFU/g feces (marked by an arrow).
