''Paramphistomum spp'' are of the family ''Paramphistomatidae''. ''Paramphistomomes'' are rare in the UK, but can cause severe losses in ruminants in the wet tropics
The adult fluke is plump and cylindrical (unusual for a [[Trematodes|trematode]]). It attaches to the wall of the rumen without causing serious damage. The eggs are like those of [[Fasciola hepatica|''Fasciola'']], but are colourless, and have long filaments present at the poles.
The intermediate hosts are water snails, and these shed '''cercariae''' which later form '''metacercariae''' on vegetation.
Disease occurs if metacercariae are eaten in large numbers. [[Enteritis]] and [[diarrhoea]] result when immature flukes migrate along the small intestine, (where the metacercariae excyst) towards the rumen.
Also see [[Trematodes - Overview]].
