Abstract

This study demonstrates that non-O157 serotypes O26:H11, O111:H8, O145:NM have similar survival and protein expression patterns in rumen fluid with variations being influenced primarily by rumen fluid composition associated with diet. Unlike STEC O157, under in vivo conditions, the growth dynamics of the non-O157 serotypes were comparable to that of non-STEC, commensal E. coli. Hence, exploring bacterial protein expression within the host is critical in discerning therapeutic targets, unique to/shared between STEC, for broad control strategies. In addition, this study further validates the value of using a non-terminal animal model for rumen studies that reduces number of animals used for an experiment.
