Paramphistomum

Paramphistomum is a genus of parasitic flatworms belonging to the digenetic trematodes. It includes flukes which are mostly parasitising livestock ruminants, as well as some wild mammals. They are responsible for the serious disease called paramphistomiasis, also known as amphistomosis, especially in cattle and sheep. Its symptoms include profuse diarrhoea, anaemia, lethargy, and often result in death if untreated. They are found throughout the world, and most abundantly in livestock farming regions such as Australia, Asia, Africa, Eastern Europe, and Russia.

The generic name was introduced by F. Fischoeder in 1901 for the replacement of the then existing genus Amphistoma (Rudolphi, 1809). Under the new genus he redescribed both Paramphistomum cervi and P. bothriophoron and designated the former as the type species.
