Gastrointestinal motility disorders represent a significant cause of morbidity and mortality in the horse. Previously regarded as a non-pathogenic tapeworm, Anoplocephala perfoliata has been recently related to equine colic. In this study pathological changes related to A. perfoliata in the ileocecal junction have been investigated in 31 regularly slaughetered horses. Our results showed a significant relationship between parasitic burden and grading of histopathological lesions in the mucosa and submucosa. In the infested horses, hypertrophy of circular muscle layer was determined. The Enteric Nervous System (ENS) evaluation showed injury of intestinal nervous elements in horses with moderate to high parasitism.

Abstract
Gastrointestinal motility disorders represent a significant cause of morbidity and mortality in the horse. Previously regarded as a non-pathogenic tapeworm, Anoplocephala perfoliata has been recently related to equine colic. In this study pathological changes related to A. perfoliata in the ileocecal junction have been investigated in 31 regularly slaughetered horses. Our results showed a significant relationship between parasitic burden and grading of histopathological lesions in the mucosa and submucosa. In the infested horses, hypertrophy of circular muscle layer was determined. The Enteric Nervous System (ENS) evaluation showed injury of intestinal nervous elements in horses with moderate to high parasitism.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
