The causative agent of opisthorchiasis in humans is quite a long life cycle and has two intermediate hosts. Eggs opisthorchis in a variety of ways fall into the fresh water reservoir, where they ingest shellfish – they are the first obligatory intermediate host. In the body of the mollusk larvae turn into cercaria, after which they again fall into the water, where they are meeting with the second intermediate host – fish. Opistorhisov embedded in the muscle of the fish through the skin. Infected fish family Cyprinidae – carp, bream, gudgeon, bullhead and others.
