The impact of liver fluke infection on the welfare of horses

Liver disease has severe implications for the welfare of horses and the underlying causes are often difficult to diagnose. The University of Liverpool is recognised internationally for its fluke research; having received enquiries about fluke infection in horses and, using a prototype diagnostic ELISA, seen a diagnostic rate of 16%. Undiagnosed liver disease is associated with deterioration of a horse’s condition over time, extensive diagnostic intervention including liver biopsies and frequently euthanasia when cause cannot be found and treated. Because so little is known about fluke in horses it is not normally considered as a cause of liver disease and there is a lack of advice on its diagnosis, treatment and prevention. This project will raise awareness of liver fluke as a differential in cases of chronic liver disease and improve advice available to vets and horse owners, reducing the suffering and early euthanasia of affected horses.
This project will establish how common liver fluke infection is as a cause of unexplained liver disease in horses, define the clinical syndrome associated with liver fluke infection to help improve diagnosis, provide advice to vets and horse owners and generally raise awareness of liver fluke as a diagnostic differential in cases of chronic liver disease. This will allow earlier diagnosis and treatment making a significant contribution to reducing the suffering and early euthanasia of affected horses.
