Parasitic trematodes (flukes) cause substantial mortality and morbidity 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. Although C. sinensis infection can be controlled relatively well using anthelmintics, the worm is carcinogenic, inducing cholangiocarcinoma and causing major suffering in ~15 million people in Asia. This chapter provides an account of C. sinensis and clonorchiasis research-covering aspects of biology, epidemiology, pathogenesis and immunity, diagnosis, treatment and control, genetics and genomics. It also describes progress in the area of molecular biology (genetics, genomics, transcriptomics and proteomics) and highlights challenges associated with comparative genomics and population genetics. It then reviews recent advances in the sequencing and characterisation of the mitochondrial and nuclear genomes for a Korean isolate of C. sinensis and summarises salient comparative genomic work and the implications thereof. The chapter concludes by considering how advances in genomic and informatics will enable research on the genetics of C. sinensis and related parasites, as well as the discovery of new fluke-specific intervention targets.

Clonorchis sinensis Promotes Intrahepatic Cholangiocarcinoma Progression by Activating FASN-Mediated Fatty Acid Metabolism.

Article Synopsis
- Clonorchis sinensis infection significantly worsens overall survival rates in patients with intrahepatic cholangiocarcinoma (ICC) compared to those without the infection.
- Researchers used RNA sequencing and animal models to investigate how C. sinensis infection facilitates the progression of ICC.
- The study found that C. sinensis infection leads to increased expression of fatty acid synthase (FASN), which promotes fatty acid synthesis and tumor growth, suggesting a potential new target for treatment in ICC patients infected with C. sinensis.
Combinatorial Treatment with Praziquantel and Curcumin Reduces Parasite Burden and Clonorchiasis-Associated Pathologies in Rats.

: Clonorchiasis is a foodborne parasitic disease that can lead to severe biliary fibrosis and cholangiocarcinoma. While praziquantel (PZQ) is available for clonorchiasis treatment, it cannot revert the histopathological damage incurred through parasite-induced fibrosis. Curcumin (CUR) is an emerging experimental drug possessing anti-inflammatory and fibrosis-alleviating effects, thus signifying its potential as an anthelmintic drug.

Background: Clonorchiasis is an important foodborne parasitic disease in China caused by Clonorchis sinensis. Accurate and rapid diagnosis of this disease is vital for treatment and control. Traditional fecal examination methods, such as the Kato-Katz (KK) method, are labor-intensive, time-consuming, and have limited acceptance.

Unlabelled: remains a non-negligible global zoonosis, imposing serious socio-economic burdens in endemic regions. The interplay between gut microbiota and the host transcriptome is crucial for maintaining health; however, the impact of juvenile infection on these factors is still poorly understood. This study aimed to investigate their relationship and potential pathogenic mechanisms.

Background: Cognition, behaviours and social environment are associated with Clonorchis sinensis infection, a prevalent liver fluke disease in China. This study aimed to use social cognitive theory (SCT) to investigate these three aspects and their interaction in an endemic area.
Methods: We conducted three semi-structured focus group discussions in Da'ao town, Jiangmen city, Guangdong Province, China.
