How is opisthorchis viverrini transmitted?
The trematode Opisthorchis viverrini is a fish-borne fluke that is commonly transmitted by ingesting raw fish containing infective metacercariae that excyst in the duodenum and migrate to the bile ducts where the adult worms reside.
What is the clinical classification of Opisthorchiasis?
Opisthorchiasis is a parasitic disease caused by species in the genus Opisthorchis (specifically, Opisthorchis viverrini and Opisthorchis felineus). Chronic infection may lead to cholangiocarcinoma, a malignant cancer of the bile ducts.

What is the habitat of Opisthorchis Viverrini?
viverrini inhabits mainly the bile ducts, and rarely, the gall bladder and pancreatic duct. Heavy infection can produce problems in the liver, gall bladder, and bile ducts. The bile ducts of heavily infected patients are usually dilated and indicate fibrosis.
What is the infective stage of Opisthorchis Felineus?
The cercariae then leave the snail, penetrate into susceptible fresh water fish, encyst in the muscle and develop into metacercariae, and infective stage, in six weeks. When ingested by man or animal the metacercariae excyst in the duodenum or jejunum and then migrate to the bile duct.
What is the habitat of Opisthorchis Felineus?
felineus: 7 mm to 12 mm by 2 mm to 3 mm) reside in the biliary and pancreatic ducts of the mammalian host, where they attach to the mucosa.
Is Opisthorchis parasitic?
Parasites – Opisthorchis Infection Opisthorchis species are liver fluke parasites that humans can get by eating raw or undercooked fish from areas in Asia and Europe where the parasite is found, including Thailand, Laos, Cambodia, Vietnam, Germany, Italy, Belarus, Russia, Kazakhstan, and Ukraine.
What is the location of Opisthorchis Felineus in the human?

What does Opisthorchis do?
Parasites – Opisthorchis Infection 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.
What is the difference between Opisthorchis and clonorchis?
sinensis (or Opisthorchis sinensis), also known as the Chinese liver fluke. It is endemic in East Asia (mainly in China, Japan, Korea, Taiwan, and Vietnam) [2], as well as far eastern Russia (figure 1) [3-5]. Clonorchis is a parasite of fish-eating mammals; dogs and cats are the most common reservoirs [6].
How is Opisthorchis treated?
Praziquantel or albendazole are the drugs of choice to treat Opisthorchis infection.
What is the infective stage of Opisthorchis Viverrini Where does it live how a human gets infected with this parasite?
The metacercarial stage is infective to humans and other fish-eating mammals, including dogs, cats, rats, and pigs. Fish contain more metacercaria from September to February, before the dry season, and this is when humans are usually infected. Infection is acquired when people ingest raw or undercooked fish.
What is opisthorchiasis in cats?
Opisthorchiasis is infection with Opisthorchis viverrini (Southeast Asian liver fluke) or O. felineus (cat liver fluke), which are acquired by eating infected raw or undercooked fish that contains infectious metacercariae (encysted stage).
What is Opisthorchis viverrini in cats?
Opisthorchis viverrini is known as the Southeast Asian liver fluke and O. felineus as the cat liver fluke. What are the signs and symptoms of infection with Opisthorchis?
How do you get rid of Opisthorchis in cats?
Chronic O. felineus infections may also involve the pancreatic ducts.Diagnosis of Opisthorchis infection is based on microscopic identification of parasite eggs in stool specimens. Safe and effective medication is available to treat Opisthorchis infections. Adequately freezing or cooking fish will kill the parasite.
What are Opisthorchis species?
Opisthorchis species are liver fluke parasites that humans can get by eating raw or undercooked fish, crabs, or crayfish from areas in Asia and Europe where the parasite is found, including Thailand, Laos, Cambodia, Vietnam, Germany, Italy, Belarus, Russia, Kazakhstan, and Ukraine.
