[Verminous enteritis and thrombo-embolic colic in the horse. A description of 36 cases (author's transl)].

Based upon case reports from 36 cases of verminous thrombosis of arteria mesenterica cranialis--all of which were verified at necropsy--clinical symptoms, course and pathological lesions are described. Seventy five per cent of the patients were under 3 years old, and 73% of the cases showed initial signs during the period July-December. Salient clinical findings were, unthrifty appearance and emaciation, diarrhoea--observed in two thirds of the patients--and colic--observed in 50 per cent of the cases. Haematological and biochemical findings were inconclusive, yet, hypoproteinaemia was a rather frequent finding. At necropsy, enteritis and/or typhlocolitis were observed in 29 horses of which 8 horses had superficial lesions, 7 horses hyperplastic lesions and 12 horses diphteroid/necrotizing lesions. Fourteen per cent of the horses had renal infarctions. The findings are discussed in relation to recent observations on the epidemiology of Strongylus vulgaris infection and comparisons are drawn to findings in a material of horses with non-parasitic enteritis.
