[Localization of C. ovis in experimentally infected lambs]

Studied were the distribution of Cysticercus ovis in cadavers of lambs experimentally infected with various amounts of Taenia ovis ova, the ratio between superficially localized cysticerci and those found deep in the individual groups of muscles and organs, and the ratio between alive and dead cysticerci. The tests were carried out with thirteen lambs treated as follows: 2 animals were infected with 1000 T. ovis ova each; 3 were infected with 4000 ova each; 4--with 7000 ova each; and 4--with 30 000 ova each. No strictly defined predilection for the localization of Cysticercus ovis was established in the body of the experimentally infected lambs. In compliance with the parasite burden in the individual organs and muscle groups per unit of mass these ranked in the following descending order: heart, diaphragm, fore and hind limbs, masticatory muscles, neck and back muscles, tongue, and abdominal and intercostal muscles. Experimentally, highest was the percent of viable cysticerci in the muscles of the fore and hind limbs and in the muscles of the neck.
