Taenia saginata asiatica

Causative agent of Asian taeniosis

This form of Taenia occurs in the small intestine of humans in East and Southeast Asia (Korea, Taiwan, the Philippines, Thailand, Indonesia, Malaysia). Genetic analysis has revealed a close subspecies-relation to T. saginata (= T. saginata asiatica). The two forms differ in a number of morphological features; in addition, the cysticerci of T. saginata asiatica develop mainly in the livers of pigs, but also infect cattle, goats, and monkey species.
