這種蟲的感染通常都是因為吃了受蟲體感染而又未經徹底煮熟的螺、蝸牛或蛙類，而這三種動物都是這種蟲的中間宿主。 This parasite is predominantly found throughout North America. Two asexual generations occur in a snail or mollusk. The first snail host is penetrated by a miracidium, producing a sporocyst. Many sporocysts are produced and mother rediae emerge. Mother rediae asexually reproduce daughter rediae, which also multiply. Each rediae then develop into a cercariae, which penetrates a second host. The second host could be another snail or a tadpole, in which development into metacercaria occurs. Cercariae typically find a snail host through chemotaxis. The cercariae are attracted to the slime of the snail, which contains small peptides. The first larval stage is the miracidium, and are found to be attracted to macrocmolecular glycoconjugates associated with a possible snail host. Environmental stimuli such as light and gravity can also be used to assist in searching for a host.[來源請求]
- Physa occidentalis
- Lymnaea stagnalis
- Lymnaea sp. in Thailand
- Radix auricularia
- Corbicula producta
- Filopaludina sp. from Vietnam serves as a second intermediate host for Echinostoma revolutum
For example in Pursat Province, Cambodia the children were fond of eating undercooked snails or clams of unidentified species sold on the road to their homes after school. It was a source of infection in humans.
The first reported human infection was in Taiwan in 1929. The prevalence of Echinostoma revolutum flukes in Taiwan during 1929–1979 varied from 0.11% to 0.65%. Small Echinostoma revolutum–endemic foci or a few cases of human infection were discovered in the People's Republic of China, Indonesia, and Thailand until 1994. However, no information is available about human Echinostoma revolutum infection after 1994, even in areas where the parasite was previously endemic. The prevalence of infection with Echinostoma revolutum flukes ranged from 7.5% to 22.4% in 4 schools surveyed in Pursat Province, Cambodia, tested fecal specimens from 471 children, 10–14 years of age, in June 2007. Authors reported echinostomiasis as an endemic trematode infection among schoolchildren in Pursat.
