Parasitic flatworms cause substantial death and disease in humans. The Chinese liver fluke, Clonorchis sinensis, is one of the most destructive parasitic worms in humans in China, Vietnam, Korea and the Russian Far East. Read more about Chinese liver flukes on Wikipedia.
Although C. sinensis infection can be controlled relatively well using drugs (anthelmintics), the worm can cause cancer (cholangiocarcinoma) and causes major suffering in ~ 15 million people infected in Asia. No vaccine is available to prevent parasite infection, and humans have no resistance to reinfection.
To better control this flatworm, research has been conducted on the molecular biology of the parasite, focused on diagnosis and treatment. A deep understanding of the fluke’s molecular biology is underpinned by characterizing its genome. Today, we release an chromosome-length genome assembly for C. sinensis, produced using our existing short read assembly and new Hi-C data. The new assembly will provide a basis to conduct in-depth molecular studies of C. sinensis and broader comparative genomics and genetics of flatworms.
