About Clonorchis sinensis

The trematode Clonorchis sinensis, or Chinese liver fluke, is a parasitic human liver fluke. The parasite lives in the liver of humans, is believed to be the third most prevalent worm parasite in the world, and is endemic to Japan, China, Taiwan, and Southeast Asia. Recent studies have proved that it is capable of causing cancer of liver and bile duct, and in fact the International Agency for Research on Cancer has classed it as a group 1 biological carcinogen in 2009.

There is 1 alternative genome project for Clonorchis sinensis available in WormBase ParaSite: PRJDA72781

Genome Assembly & Annotation


The chromosome-level assembly presented here was added in WormBase ParaSite release 16, and represents version 2 of GCA_003604175. The assembly was generated by scaffolding version 1 of the assembly with Hi-C data, paired-end and mate-pair libraries and Oxford Nanopore long-read libraries, as described by Young et al., 2021.


The gene set presented here was generated by Young et al. by transferring gene models from V1 of the assembly using liftOver, followed by further refinement with funannotate and PASA.
