unusual facts about intermediate host



E. Fuller Torrey

In the early 1970s, Torrey became interested in viral infections as possible causes of schizophrenia or bipolar disorder, particularly a parasite Toxoplasma gondii whose definitive host is the cat, but whose intermediate host can be any mammal, including humans.

Eomecon

Extracts of this plant have been effective at eliminating the freshwater snail Oncomelania hupensis, the intermediate host of Schistosoma japonicum, a fluke that causes schistosomiasis.

Fasciolopsiasis

The parasite infects an amphibic snail (Segmentina nitidella, Segmentina hemisphaerula, Hippeutis schmackerie, Gyraulus, Lymnaea, Pila, Planorbis (Indoplanorbis)) after being released by infected feces; from this intermediate host, metacercaria infest on aquatic plants like water spinach, which are eaten raw by pigs and humans.

Paracalliope

Paracalliope acts as an intermediate host for the nematode Hedruris spinigera, which can thus reach their primary host, the eel.

Cochlicella acuta

Cochlicella acuta is an intermediate host for the terrestrial trematode parasite Brachylaima cribbi.

Filopaludina

from Vietnam serves as a second intermediate host for the parasitic fluke Echinostoma revolutum.

Juga plicifera

Juga plicifera serves as an intermediate host for Nanophyetus salmincola.

Maritrema subdolum

The cercariae of M. subdolum emerge from the first intermediate host, a gastropod of the genus Hydrobia for example, and seek out the next host, a crustacean.

Schistocephalus solidus

The coracidium is then ingested by the first intermediate host, a cyclopoid copepod (e.g. Macrocyclops albidus).

Schistosoma ovuncatum

The natural final host is the rat (Rattus rattus) and the intermediate host is the pomatiopsid snail Tricula bollingi.
