【 摘 要 】

Studies were carried out on the recovery rate and cysticerci location in bovines experimentally infected with Taenia saginata eggs. Three calves of 6.5 months and one with 19 months of age were infected orally with 2 x 10(4) eggs of Taenia saginata. A fifth calf served as control. After 90 days of infection, the animals were slaughtered and organs and skeletal muscles were inspected using a slicing technique every 5 mm. From the four infected calves, 702 cysticerci were recovered, of which 570 (81.2%) were alive and 132 (18.8%) were degenerated. The recovery rate ranged from 0.01 to 1.43% with an average of 0.88%. The cysticerci presented the following anatomical distribution: hioideos muscles 02 (0.28%), kidneys 03 (0.43%), tongue 07 (1.00%), liver 12 (1.71%), lungs 15 (2.14%), diaphragm 18 (2.56%), mastication muscles 25 (3.56%), heart 49 (6.98%), anterior muscle 323 (46.00%) and posterior muscle 248 (35.33%).
