    What is rumen fluke?

    Rumen fluke (paramphistome) is a different parasite to liver fluke. Generally, mature rumen fluke do not cause clinical disease but there have been reports of disease caused by large numbers of immature rumen fluke in the small intestine, typically in youngstock. In some cases, this has resulted in ill thrift and profuse scour, while in severe cases it has been fatal in both sheep and cattle.

    The clinical importance of rumen fluke is under debate. Diagnosis of rumen fluke is through faecal egg counts in dung samples or post mortem. It is important to differentiate between liver fluke and rumen fluke eggs as only a small number of flukicides kill rumen fluke.
