[Histokinesis in experimental ovine cysticercosis]

The dynamic of the morphologic changes taking place in the viscera of lambs was followed up in lambs with an experimental Cysticercus ovis infection. The tests were carried out with 6 two-month-old lambs infected with 30,000 ova of Taenia ovis each. The animals were killed on the 2nd, 4th, 12th, 54th, and 70th day of infection, taking notes on the gross and microscopic changes in the internal organs. It was found that in the predilection sites of localization the migrating oncospheres were transformed into cysticerci around which specific granuloma were formed from the center to the periphery, consisting of eosinophile leukocytes, epitheloid and gigantic cells, lymphocytes, lymphoid cells, and outermost--a connective tissue capsule. As the result of the abundant leukocyte infiltration the cysticerci quickly perished and a suppurant was formed instead that later on was replaced by connective tissue.
