Proliferative and nonproliferative sparganosis in atypical additional hosts

The article describes cases of detection of sparganums extracted from various localization sites during surgical intervention in different animal species or during veterinary and sanitary examination of carcasses. The authors registered 5 cases of sparganosis in additional hosts (2 cats, 1 dog, snakes and 1 pig). In one case, proliferative sparganosis was diagnosed (15 specimens of sparganum were removed from the abdominal cavity of a cat), in the remaining cases, non-proliferative sparganosis was diagnosed. The distinctive features of sparganums bothridial slits (bothria) on the scolex, the presence of false segmentation on the strobilus, a flattened, elongated shape, and a milky-white color were characteristic of all the described cases of sparganosis.
