Abstract Arteritis due to Strongylus vulgaris is a well-known cause of colic in horses and don- keys. The current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by S. vulgaris infection in an adult donkey in which an- thelmintic treatment was not regularly administered. Necropsy findings of the ab- dominal cavity revealed a complete cranial mesenteric arterial obstruction due to larvae of S. vulgaris, causing severe colic. To the authors’ knowledge, a complete cra- nial mesenteric arterial obstruction due to verminous arteritis has rarely been de- scribed in horses and donkeys. Based on recent reports of fatal arterial obstruction due to S. vulgaris infection in donkeys, it may be evident to consider acute colic caused by this pathogenic parasite a re-emerging disease in donkeys and horses.
