Abstract: | Opisthorchiasis, together with its associated cholangiocarcinoma, is one of the most important human parasitic diseases on continental Southeast Asia. A great deal of epidemiological data from humans is available on this disease, particularly from the northeast of Thailand, however, only limited information is available on those aspects of the life cycle relating to its Bithynia (Gastropoda) and cyprinid fish intermediate hosts. Here we review the information which is available on the Bithynia hosts of Opisthorchis viverrini. Only one major ecological study has been carried out at one site on a single species of Bithynia. We show not only that detailed ecological studies are required to clarify the epidemiology of opisthorchiasis, but also that the taxonomic status of the Bithynia species transmitting O. viverrini requires clarification. |
