Fasciolosis, commonly known as liver fluke disease, is caused by the parasitic flatworm Fasciola hepatica, a type of trematode. The disease occurs when large numbers of immature flukes migrate through the liver tissue, when adult flukes inhabit the bile ducts, or through both processes simultaneously. While Fasciola hepatica can infect all grazing animals, it primarily affects sheep and cattle.
Rumen fluke (Calicophoron daubneyi) is another trematode increasingly detected in grazing livestock. Heavy infestations of immature flukes in the small intestine can lead to diarrhoea, weight loss and reduced productivity, especially in young or stressed animals. Both liver and rumen flukes share the same intermediate host the mud snail (Galba truncatula) and are associated with similar wet grazing environments.
This screen is undertaken in our own purpose-built laboratory, by fully trained and experienced analysts using specialist testing apparatus.Liver fluke or “Fasciola hepatica” can affect grazing animals, including horses, although it is more commonly associated with cattle, sheep, alpacas and goats. Liver fluke is picked up by the animal eating the Galba truncatula mud snail when grazing, typically in marshy/wet pasture in relatively warm conditions. Liver fluke is typically most prevalent in summer and autumn months. Symptoms can include anaemia, weight loss, chronic diarrhoea and raised liver enzymes.
Up to 2 animals of the same species can be tested as a pooled sample per kit, as long as they live and graze together. One single result will be provided. Please ensure that the box is completely filled.
Faecal screens for liver fluke are very useful in certain circumstances but if the test result is negative and you still suspect that your animals are suffering from a liver fluke infestation, we strongly recommend that you contact your vet immediately. This negative result may be due to insufficient material being submitted or due to intermittent shedding.
For larger sampling of the flock or herd please contact the office via our contact us page to discuss options.
