Histopathology of trichinellosis in wild boar.

Histopathological study of Trichinella constitutes an important knowledge base to understand the pathogenesis of this disease. This study analyses cell response and macroscopic lesions in wild boar for the two species of Trichinella present in Spain: Trichinella spiralis and T. britovi. We carried out both trichinelloscopy and artificial digestion to calculate the parasitic load and relate this to the macroscopic lesions. The results obtained prove a lesser adaptation of T. britovi in wild boar. From a histological point of view, the organic region that was most affected was the skeletal muscle, where inflammatory infiltrates were observed around the larvae, and they were most abundant in calcified cysts.
