On the pathology and localisation of Cysticercus ovis in the skin of sheep.

Histological studies were conducted with experimentally and spontaneously infected lambs on the localisation of T. ovis larvae in the subcutaneous connective tissue and in the skin. In the first few days following infection an inflammatory process in the papillar and reticular skin layers was found, causing skin defects which appeared on tanning. Forty days after infection the mature cysticerci caused atrophic changes. Openings of 6-8 mm in diameter, evident on the tanning of the skin, appeared. These injuries reduced significantly the quality and the economic value of the skins.
