Clonorchiasis, commonly known as Chinese liver fluke disease, is an infection caused by trematode worms (or flukes) that is transmitted through food. Our company offers comprehensive services for the development of clonorchiasis vaccines, leveraging cutting-edge research and advanced technologies, providing high-quality services to support your research.
Introduction to Clonorchiasis
Clonorchiasis, caused by the trematode Clonorchis sinensis, remains a significant public health concern, particularly in East Asia. Recent studies indicate that the prevalence of this infection can reach up to 20% in endemic areas, especially among individuals who consume raw or undercooked freshwater fish. The disease is associated with various complications, including cholangitis and an increased risk of cholangiocarcinoma.

Diagnosis Development of Clonorchiasis
Recent years have seen significant progress in the development of diagnostic methods for clonorchiasis, focusing on two key areas:
Molecular Diagnostics
Recent advances include optimized PCR methods for improved sensitivity and specificity. Real-time PCR now enables accurate parasite load quantification. LAMP technology shows promise for rapid, field-deployable testing. Digital droplet PCR is being explored for detecting low-intensity infections, potentially revolutionizing early-stage diagnosis.
Biomarker Discovery & Development
Multi-omics approaches have identified new biomarkers. Proteomic studies revealed specific C. sinensis excretory-secretory products as potential indicators. Circulating miRNAs show potential as non-invasive biomarkers. Metabolomic research has uncovered signatures in individual biofluids. These discoveries may lead to more accurate diagnostics for early detection and disease monitoring.
Vaccine Development for Clonorchiasis
There was no commercially available vaccine for clonorchiasis. Research was ongoing, but no fully approved and deployed vaccine had been developed. Most studies were still in the laboratory and animal testing phases. Researchers have identified several promising vaccine targets.
- Excretory-Secretory (ES) Products: These are proteins secreted by the parasite that play crucial roles in host-parasite interactions. Examples include cysteine proteases and glutathione S-transferases of C. sinensis, which have been identified as potential vaccine candidates.
- Tegumental Proteins: These proteins are located on the parasite's surface and interact directly with the host immune system. For instance, tegumental antigen B2 has shown some protective immune responses.
- Metabolic Enzymes: Key enzymes involved in parasite survival and reproduction. Structural proteins like actin and myosin are also being considered as potential targets.
