Resumo: In a commercial herd of 1250 wild boars, 56 animals were affected by anorexia, diarrhea, and wasting. Enlargement of mesenteric lymph nodes, thickening of ileal wall, and a white-yellowish ileal content were observed in two of the four animals necropsied. Microscopically, ileal crypts showed epithelial hyperplasia, moderate decrease in goblet cell density, lymphohistiocytic infiltrate in the lamina propria, and moderate depletion with histiocytic infiltrate in Peyer's patches. Curved rod-shaped organisms within the apical cytoplasm of enterocytes were observed in both Warthin-Starry and Lawsonia intracellularis-immunostained sections. PCV2 antigen was observed in ileal Peyer's patches of 3 wild pigs. Trichuris suis nematodes were found in the cecum of the four wild pigs. This report describes clinicopathological findings in cases of enteritis associated with Lawsonia intracellularis and PCV2 infection in a commercial herd of wild boars.
