Clonorchis sinensis
Clonorchis sinensis
Clonorchis sinensis (pronounced: klo-NOR-kis si-NEN-sis), also known as the Chinese liver fluke, is a human liver fluke belonging to the class Trematoda, phylum Platyhelminthes. This parasite lives in the liver of humans, and can also be found in the gall bladder and bile ducts.
Etymology
The name Clonorchis sinensis comes from the Greek klon meaning twig, and orchis meaning testicle, referring to the branched testes of the organism. Sinensis is Latin for "from China", indicating the geographical origin of the species.
Life Cycle
The life cycle of Clonorchis sinensis involves two intermediate hosts. The first is a snail, where the eggs hatch into miracidia, which develop into sporocysts, rediae, and then cercariae. The cercariae are then released and infect a second host, a freshwater fish, where they encyst in the muscles or under the scales. When humans consume undercooked or raw infected fish, the flukes excyst in the duodenum, ascend the bile duct, and mature in the liver.
Symptoms and Treatment
Infection with Clonorchis sinensis can lead to a disease known as clonorchiasis. Symptoms can include abdominal pain, fever, and jaundice. Chronic infection can lead to liver diseases such as cirrhosis and cholangiocarcinoma. Treatment typically involves the use of antiparasitic drugs such as praziquantel.
Prevention
Prevention of Clonorchis sinensis infection primarily involves proper cooking of freshwater fish and good sanitation practices to prevent contamination of water sources.
