What is the life cycle of Clonorchis sinensis?
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 (cercariae). 3. The cercariae penetrate the skin of a freshwater fish and form cysts in the tissues of the fish.

What type of organism is Clonorchis sinensis?
Parasites – Clonorchis Clonorchis is a liver fluke parasite that humans can get by eating raw or undercooked fish 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.
Is Clonorchis sinensis dioecious?

What is the host for the Redia stage?
In presence of water, the miracidium escapes from the egg, actively swims, searches and infects the specific gastropod mollusc. In this host, through larval stages of sporocyst, redia (sometimes two generations), it gives origin to many cercariae (about 4,000 from one miracidium, more than 500,000 from one snail).
What is the intermediate host of Clonorchis sinensis?
There are three hosts in the life cycle of C. sinensis including freshwater snails (the first intermediate hosts), freshwater fish and occasionally shrimps (the second intermediate hosts), and human or carnivorous mammals (the definitive hosts).
What are the preventive and control measures of Clonorchis sinensis?
Do not eat raw or undercooked freshwater fish. Lightly salted, smoked, or pickled fish can contain infectious parasites. Drinking river water or other nonpotable water will not lead to infection with Clonorchis.
