ABSTRACT
Calicophoron daubneyi is the primary rumen fluke (RF) found in Europe in ruminants and infection is more common in cattle than in sheep. The incidence of RF has appeared to increase greatly throughout Europe in the last 10-15 years, with outbreaks of clinical paramphistomosis confirmed in ruminants in many countries, including Great Britain and Ireland. Clinical disease, due to immature stages developing in the small intestine, appears infrequently but can occur, usually in the autumn or winter within weeks of beginning to graze wet pasture. Although disease due to adult RF has not been proven, subclinical production losses have been attributed to adult RF infection by some researchers. As the intermediate host for RF and the liver fluke (Fasciola hepatica) is the mud snail (Galba truncatula), similar habitats and environmental conditions favour both parasites. There may, however, be differences in parasite development and interactions within both the final and intermediate hosts. No anthelminthic product is licensed for treatment of ruminants for RF in the UK. However, oxyclozanide, licensed for the treatment of adult F. hepatica infection, has been shown to have activity, but it may be more effective against the adult than the immature stages. The future prevalence of RF due to climate change and limited treatment options is unpredictable. Infection and clinical disease could become more common and RF is worthy of further research.
