title: Pathological alterations caused by Anoplocephala perfoliata infection in the ileocaecal junction of equids.
abstract: The pathological alterations caused by Anoplocephala perfoliata in the ileocaecal junction of 28 equids slaughtered in an abattoir in Madrid (Central Spain) are described. The lesions were scored in grades based on the intensity of the damage and were related to the tapeworm number observed. The first grade (grade I) of alterations consisted of a slight enteritis associated with focal erosions observed in 43% of parasitized animals with low parasitic burden (1-26 tapeworms). The second grade (grade II) was a focal pseudomembranous enteritis, present in the ileocaecal junctions of 36% infected animals with moderate to high burden (23-188 tapeworms), and the third grade (grade III) was a regional necrotizing enteritis, present in the animals (21%) with the highest burden (72-248 tapeworms). The possible role of the lesions caused by this parasite in the aetiology of colic is discussed.
