What is liver fluke?
Liver fluke disease is a chronic parasitic disease of the bile ducts. Infection with this parasite occurs through eating fluke-infested, fresh-water raw or undercooked fish. The most common types of liver flukes are Clonorchis sinensis, Opisthorchis viverrini and Opisthorchis felineus. Approximately 35 million people are infected ...
What blood test shows a liver fluke?
Tests for liver fluke infection (fascioliasis) You will need a full blood count – this may show elevation of a type of white blood cell. These white blood cells are known as eosinophils. The blood eosinophil count will usually be high (over 500 to 1000 eosinophils per μl of blood).

Consumer education is crucial to make people aware of the need to stop eating raw fish.
Can liver fluke cause indigestion?
If liver fluke is left undetected for years, this can become a very serious disease and cause destruction of the liver. Most people with liver fluke infection are completely unaware because they experience no symptoms at all. A small percentage of patients experience fatigue and non-specific abdominal discomfort, which easily gets mistaken for indigestion or irritable bowel syndrome. So, it is important to have a high awareness of this insidious and destructive liver disease.
What is the best treatment for fluke infection in sheep?
Most flukicidal drugs on the market are effective in treating chronic fasciolosis, because they kill adult fluke, but few are effective in treating acute fluke infections in sheep caused by the immatures migrating through the liver. Triclabendazole (TCBZ) is generally the drug of choice but as resistance to flukicides can occur with repeated and frequent use, alternatives should be used wherever possible, particularly in late winter and spring, to reduce potential for the development of TCBZ-resistance.
When to use fasciolicide for TCBZ?
For treatment in late summer and autumn, a fasciolicide that is active against immature fluke is recommended. Treatment may need to be repeated in winter (January). If a spring treatment is required (April-June), then a flukicide with adult activity only can be used, reducing the selection pressure associated with TCBZ.
How to monitor sheep fluke burdens?
Fluke burdens can be monitored in sheep flocks by post-mortem examinations when the opportunity arises, or with FECs . Flocks should be monitored before a fasciolicide is used unless there is a history of fluke infection on the farm. Continued monitoring can help determine the need for repeated treatments.
Does Closantel help Fasciola hepatica?
However, there is evidence that closantel combinations have a synergistic activity that may enhance their activity against resistant Fasciola hepatica (and Haemonchus contortus, the Barber's pole worm ), and also help delay the emergence of resistance to either class of compound.
Symptoms of Liver Fluke
People can get infected with liver flukes after swallowing the parasite, most often by eating raw vegetables or drinking contaminated water.
Life Cycle of the Liver Fluke
Infected animals excrete immature eggs through their stool. These eggs develop in freshwater, using snails as an immediate host to undergo several developmental stages. The snail later releases the eggs onto plants, which are ingested by grazing animals and passed on to humans, where they live to adulthood.
Diagnosis of Liver Fluke Infection
Diagnosis of liver fluke infection is made through some of these tests:
Treatment of Liver Fluke
Liver fluke infection is treatable. You should consult a professional if you suspect you have a liver fluke infection to prevent complications.
Prevention
Liver fluke infections are easily preventable. Prevention methods may include:
When to use FECs for liver fluke?
Due to the seasonality of liver fluke and the fact that they commence shedding eggs 10-12 weeks post infection, FECs are more useful at certain times of the year (e.g., winter and spring).
How long does a bovine liver fluke last?
Liver fluke – Fibrotic bovine liver The longevity of fluke in cattle is about 1-2 years. When the bovine liver is infected, it provokes an immune response leading to a fibrotic reaction which prevent the fluke from migrating and feeding (Image from Andrew Forbes, University of Glasgow).

How long does a Fasciola hepatica live?
The length of the complete life cycle of Fasciola hepatica (Liver fluke) is very long and varies depending on the season as it requires a definitive host (cattle or sheep) and an intermediate host (mud snail), although the minimum period for the whole life cycle is 5 – 6 months.
Can sheep get liver fluke?
Unlike most other parasitic diseases of ruminants, liver fluke is not host species-specific and grazing sheep with cattle on high risk pasture can potentially amplify the disease. There is little evidence to suggest that cattle or sheep develop significant immunity to liver fluke. As sheep shed higher numbers of liver fluke eggs than cattle, co-grazing would benefit sheep but could be detrimental to cattle.
