Attaching and effacing lesions in the large intestine of an eight‐month‐old heifer associated with Escherichia coli 026 infection in a group of animals with dysentery

Abstract
Escherichia coli O26:K60, with genetic attributes consistent with a potentially human enterohaemorrhagic E coli was isolated from the faeces of an eight-month-old heifer with dysentery. Attaching and effacing lesions were identified in the colon of a similarly affected heifer examined postmortem, and shown to be associated with E coil 026 by specific immunolabelling.
