Abstract
The infectivity of metacestodes of Asian Taenia saginata, now tentatively called Taenia saginata taiwanensis, in human host was confirmed. The metacestodes used in experimental infection were collected from the livers of naturally infected domestic pigs at an abattoir in Cheongju City, Korea. The first gravid proglottid was spontaneously discharged 76 days after infection. Two worms were recovered two years later by chemotherapy. The scolex was unarmed. The number of main uterine branches, varying from 16 to 21, was similar to that of classical Taenia saginata. The liver of pigs was confirmed to be an infection source of Asian T. saginata in Korea.
