  • Title: Pathological changes in the small intestine of neonatal calves naturally infected with reo-like virus (rotavirus).
    Author: Pearson GR, McNulty MS, Logan EF.
    Journal: Vet Rec; 1978 May 27; 102(21):454-8. PubMed ID: 208222.
    Abstract:
    Nine calves, of which six had been challenged with an enteropathogenic strain of Escherichia coli, were found to be naturally infected with rotavirus. Rotavirus was recovered from the faeces of six calves and rotavirus antigen was detected in the intestinal mucosa of all calves. Stunting and fusion of villi were seen principally in the proximal and middle small intestine, where rotavirus antigen was detected by immunofluorescence. Typical lesions of enteric colibacillosis were found in the distal ileum of the challenged calves, associated with adhesion of the challenge strain of E coli to the mucosa. All samples were removed from the intestine under general anaesthesia and denudation of villi was not observed. However, following exsanguination and resampling at the same site in the small intestine of one calf, denudation was a constant feature.
