Research Abstract

Parasitological survey on human taeniid cestods was don in Tibetan Plateau, Sichuan, China and Bali, Indonesia. In Tibetan Plateau, three human Taenia, Taenia solium, Taenia saginata and Taenia asiatica were endemic sympatorically. In Bali, T. solium was endemic in the northern part of island a d T. saginata was endemic in the southern part. In addition, hybrid between T. saginata and T. asiatica was found in Tibetan Plateau. We examined the molecul ar and immunological diagnostic methods for human taniasis/cysticercosis, which were developed by our research group. We also evaluated the risk of domestic animals for endemic of human taniasis/cysticercosis.
