The objective of this study was to determine the association between Equine Rotavirus (ERV) infections and gastric and/or duodenal lesions. An endoscopic examination of the stomach and duodenum and an examination of stool samples for the presence of ERV were performed on 41 thoroughbred foals with diarrhea. 58.5% (24/41) of the stool samples tested positive for ERV, while 95% (38/41) of the stomachs and 33.3% (7/20) of the duodenums were found to have lesions. There was no association between the severity and prevalence of gastric lesions and the presence of ERV. The prevalence of duodenal lesions was significantly higher (P0.05) when test results for ERV were positive (54.6%) than negative (10.0%). Clinical signs were not affected by the presence of ERV. It is reasonable to conclude that most foals with diarrhea, regardless of the presence or absence of ERV, have gastric lesions, and that lesions of the duodenum are associated with ERV.
