Siderophore-receptor and porin-based (SRP) Escherichia coli vaccine technology functions by starving the E. coli organism via competitive exclusion for proteins that scavenge iron, an essential nutrient for E. coli viability. Vaccination with SRP E. coli technology decreased the prevalence of E. coli O157:H7 in artificially inoculated cattle and in cattle naturally shedding the organism. Examination of the effects that SRP E. coli vaccines exert on performance parameters has yet to be attempted in a commercial setting. The use of SRP E. coli vaccine technology effectively decreases the prevalence of E. coli O157:H7 in feeder cattle and may improve beef safety; …
