Bovine paramphistomes in Ireland.

Paramphistome infections have been associated with significant morbidity, caused chiefly by the activity of juvenile flukes in the intestine of the ruminant final host. Most cases have been reported in tropical and sub-tropical areas. However, recent reports of an apparent increase in the incidence of rumen fluke and its geographical range in Europe have renewed interest in a parasite previously thought to be of little significance in temperate regions. Moreover, the identity of rumen flukes present in the British Isles is currently being revised. As a result, work is underway throughout Europe to review and re-assess the clinical and economic significance of rumen flukes.
