What is the classification of liver fluke?
Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes. It infects the livers of various mammals, including humans, and is transmitted by sheep and cattle to humans the world over.
What class do flukes belong to?
class Trematoda
What type of worm is a liver fluke?
A liver fluke is a parasitic worm. Infections in humans usually occur after eating contaminated raw or undercooked freshwater fish or watercress. After liver flukes have been ingested, they travel from your intestines to your bile ducts in your liver where they then live and grow.
What is the classification of fasciola?
Flukes
Which disease is caused by liver fluke?
Fascioliasis is an infectious disease caused by Fasciola parasites, which are flat worms referred to as liver flukes. The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle.
What is the life cycle of liver fluke?
Following ingestion, the young flukes migrate to the liver, through which they tunnel, causing considerable tissue damage. The infection is patent about 10-12 weeks after the metacercariae are ingested. The whole cycle takes 18-20 weeks.
Is liver fluke free to live?
Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma. In these organs, they produce pathological lesions leading to parasitic diseases. They have complex life cycles requiring two or three different hosts, with free-living larval stages in water.
How long do liver flukes live in humans?
Liver flukes infect the liver, gallbladder, and bile duct in humans. While most infected persons do not show any symptoms, infections that last a long time can result in severe symptoms and serious illness. Untreated, infections may persist for up to 25–30 years, the lifespan of the parasite.
Can you see liver flukes in stool?
Diagnosis of Fluke Liver Infections Doctors diagnose Clonorchis, Opisthorchis, or Fasciola infections when they see fluke eggs in a person’s stool (feces) or in the contents of the person’s intestines. However, finding eggs in stool may be difficult.
Where do flukes live in humans?
Few flukes (Fasciola hepatica) live on the gills, skin, or outside of their hosts, while others, like blood flukes (Schistosoma), live inside their hosts. Humans are infected by Fasciola hepatica when raw or improperly cooked food is ingested.
What is the most widespread human disease caused by flukes?
Schistosomiasis is an acute and chronic parasitic disease caused by blood flukes (trematode worms) of the genus Schistosoma.
Can liver flukes cause weight gain?
Once inside cattle, metacercariae migrate through the gut wall, cross the peritoneum and penetrate the liver capsule and bile ducts. Symptoms associated with liver flukes include reduced weight gain, reduced milk yields, reduced fertility, anemia, and diarrhea.
Does parasites cause weight gain?
Because parasites come in so many different shapes and sizes, they can cause a very wide range of problems. Some consume your food (from inside your body), leaving you hungry after every meal and unable to gain weight.
What kills pinworms in humans?
Pyrantel pamoate is in most over-the-counter (OTC) treatments for pinworms. This includes Reese’s Pinworm Medicine and Pin-X. Prescription-strength medications are also available. Your doctor may prescribe a two-dose treatment of mebendazole or albendazole to help you clear the infection.
