The study showed tree frog tadpoles acted as "sponges" for the trematode parasites, which were subsequently killed by the immune systems of frog tadpoles, said Johnson. As a result, fewer ...

Host snails release parasite larvae in the water, infecting amphibians and causing deformities that include extra or missing legs. Deformed frogs and toads rarely survive long because of their ...

The trematodes go through three different hosts in their life cycle. When their eggs hatch, the larvae infest aquatic snails. As they mature, they move on to frogs, where they burrow in, forming ...

All 15 leopard frogs were infected by the trematode Ribeiroia ondatrae, a parasite that has been well-documented in Dr. Johnson’s other papers to cause malformations depending on the intensity of ...

The trematode life cycle moves through three hosts. It begins with the snail, where the parasite matures and releases free-swimming larvae called cercariae.

While infections are most common in East Asia and South America, foodborne trematode infections lead to around 200,000 illnesses and 7,000 deaths each year—though these are likely underestimates ...

Scientists have predicted that the rate of foodborne trematode infections will remain stable up to 2030. Foodborne trematodiases, including clonorchiasis, fascioliasis, fasciolopsiasis ...

Linked with existing laboratory studies showing that the trematode known as Ribeiroia ondatrae can cause the frogs to sprout extra legs, the new field work closes the loop by showing a direct ...
