Sebastiano Rivolta is generally credited with discovering the first opisthorchid, which he named Distoma felineus, in a cat in Italy in 1884.
Clonorchis sinensis and Opisthorchis viverrini are both categorized by the International Agency for Research on Cancer (IARC) as Group 1 carcinogens. [ 6 ] In humans, the onset of cholangiocarcinoma occurs with chronic opisthorchiasis, associated with hepatobiliary damage, inflammation, periductal fibrosis and/or cellular responses to antigens ...
Along with other helminth parasites Clonorchis sinensis and Opisthorchis viverrini, S. haematobium was declared as Group 1 (extensively proven) carcinogens by the WHO International Agency for Research on Cancer (IARC) Working Group on the Evaluation of Carcinogenic Risks to Humans in 2009. [6]
Opisthorchiidae is a family of digenean trematodes. Opisthorchiidae have cosmopolitan distribution. [1]The most medically important species in the family Opisthorchiidae are Clonorchis sinensis, Opisthorchis viverrini, and Opisthorchis felineus, [1] that are causes of the disease clonorchiasis.
There are three main kinds of parasites: Clonorchis sinensis (a trematode/fluke), Anisakis (a nematode/roundworm) and Diphyllobothrium (a cestode/tapeworm). Infection by the fish tapeworm Diphyllobothrium latum is seen in countries where people eat raw or undercooked fish, such as some countries in Asia, Eastern Europe, Scandinavia, Africa, and ...

Clonorchiasis is a known risk factor for the development of cholangiocarcinoma, a neoplasm of the biliary system. [ citation needed ] Symptoms of opisthorchiasis caused by Opisthorchis viverrini and by O. felineus are indistinguishable from clonorchiasis caused by Clonorchis sinensis , [ 6 ] leading some to argue that the disease by these three ...
