title: Comparison of diversities of Escherichia coli O157 shed from a cohort of spring-born beef calves at pasture and in housing.
abstract: A cohort of spring-born beef calves demonstrated limited genetic and phenotypic diversity of Escherichia coli O157 when kept in a state of isolation. Despite this, there was a difference in the pulsed-field gel electrophoresis and phage types of isolates shed by cattle at pasture compared with those shed by the same cattle when weaned and housed.
