title: [Ostertagiasis in bulls used for bullfights].
abstract: In this paper, an outbreak of ostertagiosis in fighting-bull calves is described. Of 95 calves, 12 were affected and 10 died. Grossly, the abomasal mucosa was aedematous and showed multiple whitish tiny nodules. Differential diagnoses at a macroscopic level included parasitization by E. gilruthi. However, histologically the presence of Ostertagia spp. larvae in the lumen of the gastric glands was confirmed. The inflammatory reaction observed in the abomasal mucosa, together with the clinical picture, correspond to type-II ostertagiosis, with metaplasia, hyperplasia, dilatation, and parasitic forms in the gastric glands.
