aEach group represents the cumulative number of pigs from three separate experimental replications. bNon-pathogenic E. coli strain. cSTEC strain.
Three week old piglets were orally inoculated with either pathogenic STEC strain 1191 (probiotic and sham groups) or non-pathogenic E. coli strain 123 (negative control group). STEC inoculated pigs were treated with either a Shiga toxin 2e receptor mimic probiotic (probiotic group) or a sham probiotic strain which lacked the receptor mimic (sham group). Treatment was administered twice daily, and was initiated 24 hours post-inoculation with the STEC strain.
