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]
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).
Clonorchiasis is an infectious disease caused by the Chinese liver fluke (Clonorchis sinensis) and two related species.Clonorchiasis is a known risk factor for the development of cholangiocarcinoma, a neoplasm of the biliary system.
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]
The larvae are released into the environment from which the definitive hosts (humans and other mammals) acquire the infection. In some species another intermediate host is required, generally a cyprinid fish, and the definitive hosts are infected from eating infected fish. Hence, these species are food-borne parasites.
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 ...
Life cycle of Clonorchis sinensis, a liver fluke associated with cholangiocarcinoma. Although most people present without any known risk factors evident, a number of risk factors for the development of cholangiocarcinoma have been described.
The Life Cycle of Gastrodiscoides hominis. Humans are now considered as the accidental host because humans are not the primary requirement for the life cycle; pigs are recognised as the principal definitive host. Infection causes a helminthic disease called gastrodiscoidiasis. [6]
