Clonorchis sinensis under a light microscope: Notice the uterus; this species is monoecious. An adult C. sinensis is a flattened (dorsoventrally) and leaf-shaped fluke. The body is slightly elongated and slender, measuring 15–20 mm in length and 3–4 mm in width. [10]
Clonorchis sinensis is a trematode (fluke) which is part of the phylum Platyhelminthes. The parasitic worm is as long as 10 to 25 mm and lives in the bile ducts of the liver. It is a hermaphroditic fluke that requires two intermediate hosts. The eggs of the worms are passed in fecal matter into a body of water and are then ingested by mollusks.
Clonorchiasis is a parasitic infection caused by the Chinese liver fluke, Clonorchis sinensis. [14] The disease is prevalent in East Asia, including China, Korea, Vietnam and parts of Russia. The transmission of clonorchiasis occurs through the ingestion of raw or undercooked fish that are infected with the larvae of Clonorchis sinensis. Once ...
Clonorchis sinesis, a species which causes trematodiases that infect the liver. Clonorchis sinensis and Opisthorchis viverrini are two species that can cause trematodiases that infect the liver. These are more prevalent in males than females, and more common in adults than children. [5]
Fasciola hepatica Egg of Dicrocoelium sp.. Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. [1] They are principally parasites of the liver of various mammals, including humans.
From the Greek opisthen (behind) and orchis (testicle), Opisthorchis is a genus of trematode flatworms whose testes are located in the posterior end of the body. Sebastiano Rivolta is generally credited with discovering the first opisthorchid, which he named Distoma felineus, in a cat in Italy in 1884.
His report was the pioneer description of the life cycle of the fluke and the prevalence of gastrodiscoidiasis. [1] In his survey of three villages in Assam, there was found a surprisingly high incidence, with over 40% of the population was infected. J. J. C. Buckley's report is the most useful to the modern classification of G. hominis. [11]
Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
