      co3: Clonorchis sinensis, liver biopsy:  
      Clonorchis sinensis adults  is 10-25 mm by 3-5 mm,
      O.viverrini is 5,4-10 by 0,8-1,9 mm.
      The adults live in the distal bile ducts and may survive for 30-40 years,
      causing irritation to biliary cells and inflammation.

      co4: Clonorchis sinensis, liver biopsy: most infections are asymptomatic.
      Clinical manifestations can be observed in adults due to obstruction
      and dilatation of biliary ducts, cholangitis and in some cases cholangiocarcinoma. 

      co4a: Cholangiocarcinoma caused by chronic infection with C.sinensis.
