Rapid reduction and clearance of the pathogen after challenge infection. (A) Mean bacterial excretion over time after a challenge infection with an F18-fimbriated STEC strain. Error bars represent the standard deviation. The dashed line represents the detection limit (200 CFU/g feces). (B) The percentage of piglets with detectable excretion levels of the F18+ STEC strain over time. CFU: Colony forming units. dpc: days post challenge. *Indicates significant differences compared to the control group. **: p <.01, ***: p <.001. †one piglet in the control group was euthanized due to severe symptoms of edema disease. n = 8 per group.
