From a Colorado enterprise annually fattening about 50,000 lambs, 3,664 animals were examined for muscular cysticercosis. Of the total number, 406 (11.1%) were parasitized, wheras an estimated 0.1% of Colorado lamb carcasses are infected. Of the infected lambs, 60% had cardiac lesions. Two types of cysticerci-viable and degenerated-were found. The lambs probably acquired infection from grazing summer ranges and pastures where coyotes or dogs infected with Taenia ovis contaminated the forage. |
