How is clonorchis sinensis transmitted? - FindAnyAnswer

  1. Transmission: There is no vector in Fasciola hepatica transmission. Transmission occurs through the ingestion of raw, fresh-water vegetation on which the flukes in their metacercariae form are encysted
  2. Clonorchiasis is a common infection of dogs and other fish-eating carnivores (reservoir final hosts) in China, the Democratic People's Republic of Korea, the Republic of Korea and Viet Nam. The transmission cycle is similar to that of both opisthorchiasis viverrini and opisthorchiasis feline
  3. ated dish is most important in the process. Regardless of whether the sharing households are infected or uninfected the receivers could become infected
  4. C . sinensis, as a fish-borne zoonosis, presented novel transmission patterns which explained high infection rate in endemic areas; infection rate of C . sinensis was frequency-dependent and dose-related. Humoral immunity played a prevalent role in resisting to C . sinensis based on the rat models
  5. Clonorchis sinensis transmission. People become infected by eating raw or undercooked freshwater fish containing the Clonorchis larvae. Lightly salted, smoked, or pickled fish may contain infectious parasites. Drinking river water or other nonpotable water will not lead to infection with Clonorchis
  6. Clonorchis is a liver fluke parasite that humans can get by eating raw or undercooked fish, crabs, or crayfish from areas where the parasite is found. Found across parts of Asia, Clonorchis is also known as the Chinese or oriental liver fluke. Liver flukes infect the liver, gallbladder, and bile duct in humans

Clonorchis sinensis is a fish borne trematode that triggered foodborne disease, namely, clonorchiasis, to occur. The transmission of this parasite to humans is mostly through the consumption of raw freshwater fish MODE OF TRANSMISSION: Ingestion of raw or improperly cooked freshwater fish or crayfish containing encysted larvae . INCUBATION PERIOD: Variable; depends on the number of worms present; flukes may reach maturity within 1 month after encysted larvae ingeste

Clonorchis sinensis, the Chinese liver fluke, is a liver fluke belonging to the class Trematoda, phylum Platyhelminthes. It infects fish-eating mammals, including humans.

Clonorchis sinensis, a high-risk pathogenic human liver fluke, provokes various hepatobiliary complications, including epithelial hyperplasia, inflammation, periductal fibrosis, and even cholangiocarcinogenesis via direct contact with worms and their excretory-secretory products (ESPs). These pathological changes are strongly associated with persistent increases in free radical accumulation. Clonorchis sinensis has two GSTo isoforms: CsGSTo1 and 2. These enzymes are specifi-cally expressed in the reproductive system and play important roles in the protection of these organs during maturation and the response to oxidative stress [13].

Clonorchis sinensis | Introduction to Medical Parasitology. The Chinese liver fluke Clonorchis (Opisthorchis) sinensis is widely distributed in the Far East. This fluke is quite common in China, Japan, Korea, Taiwan and Vietnam among others. Although man is the main host, the parasite also infects cats, dogs and other fish-eating carnivores. Summary Clonorchis sinensis is a parasite transmitted through ingestion of raw freshwater fish, as well as improperly dried or pickled fish. The condition that Clonorchis sinensis causes is called Clonorchiasis. Chronic Clonorchiasis is notable for causing biliary tract disease, including gallstones, cholangitis, and cholangiocarcinoma Clonorchiasis, caused by Clonorchis sinensis (C. sinensis), is an important food-borne parasitic disease and one of the most common zoonoses. Currently, it is estimated that more than 200 million people are at risk of C. sinensis infection, and over 15 million are infected worldwide. C. sinensis infection is closely related to cholangiocarcinoma (CCA), fibrosis and other human hepatobiliary. Clonorchis sinensisis a major food-borne fluke in Southeast and East Asia, chiefly endemic in China, North of Vietnam, South of Korea and the Eastern portion of Russia ( Hong & A ; Fang, 2012 ) .

Life Cycle of Clonorchis sinensis. 1. In people, adult flukes release eggs through the bile ducts into the intestine. Fluke eggs are passed in stool (feces). 2. In the environment, the eggs are ingested by snails. Inside the snail, the eggs go through several stages to develop into an immature form of the fluke that has a tail and can swim. Clonorchis sinensis is a fish-borne trematode endemic to East Asia, which infects over 35 million people globally. In the study described here, we developed a nested polymerase chain reaction (PCR) method for the specific and reliable detection of C. sinensis Clonorchis sinensis is a zoonotic parasite causing clonorchiasis-associated human disease such as biliary calculi, cholecystitis, liver cirrhosis, and it is currently classified as carcinogenic to humans for cholangiocarcinoma.

The risk of Clonorchis sinensis infection can be greatly reduced by making sure that all freshwater fish are thoroughly cooked. Numerous other parasites inhabit fish found in freshwater and even in areas where Clonorchis sinensis is rare, it is still a good idea to cook fish all the way through Clonorchis sinensis infection could trigger strong immune responses in mice and humans. However, whether the C.sinensis infection has an impact on arthritis is unknown. Here we investigated the effect of C.sinensis infection on type II collagen-induced arthritis in BALB/c mice.
