The trematode Clonorchis sinensis (Chinese or oriental liver fluke) is an important foodborne pathogen and cause of liver disease in Asia. This appears to be the only species in the genus involved in human infection.

For Clonorchis and Opisthorchis spp. ova and parasite testing, contact Parasitological diagnosis DPDx. Liver flukes are trematode flatworms, including Clonorchis sinensis; Fasciola hepatica and F. gigantica; Opisthorchis felineus and O. viverrini.

Clonorchis sinensis, the Chinese liver fluke, is a liver fluke belonging to the class Trematoda, phylum Platyhelminthes. It infects fish-eating mammals, including humans. In humans, it infects the common bile duct and gall bladder, feeding on bile.

Apr 22, 2024 · Clonorchis is a liver fluke (type of parasitic worm) that can infect the liver, gallbladder, and bile duct. Clonorchis (also known as Chinese liver fluke disease), is part of the Opisthorchiidae family of liver flukes.

Clonorchis is a type of flat, leaf-shaped parasitic worm, also known as a "liver fluke." Clonorchis occurs in parts of Asia. People can get Clonorchis by eating raw or undercooked freshwater fish contaminated by larvae (young worms).

Clonorchiasis is infection with the liver fluke Clonorchis sinensis. Infection is usually acquired by eating undercooked freshwater fish. Most infections are asymptomatic, but when present, symptoms include right upper quadrant abdominal pain, indigestion, fatigue, and diarrhea. Diagnosis is by identifying eggs in the feces or duodenal contents.

In the Opisthorchiidae family, the three liver flukes, Clonorchis sinensis, Opisthorchis viverrini, and Opisthorchis felineus, are of considerable public health relevance since they cause high infection rates and severe morbidity and mortality (1, 2).

Three of the human liver flukes, Opisthorchis viverrini, O. felineus and Clonorchis sinensis, are Pathologically important food-borne members of the class Trematoda (Beaver et al., 1984). These flukes establish a chronic infection within the smaller intrahepatic bile ducts and occasionally in the pancreas and gall-bladder of humans and other ...

The three major liver flukes (trematodes) that infect humans are Clonorchis sinensis, Opisthorchis species, and Fasciola hepatica [1]. The North American liver fluke, Metorchis conjunctus, is a less common liver fluke.

The aim of this review is, therefore, to draw realistic pictures of the past and present scientific reports on the epidemiology and biology of C. sinensis and Opisthorchis spp. infection in Vietnam. Keywords: Clonorchis sinensis; Intermediate hosts; Opisthorchis spp.; Small liver flukes; Vietnam.
