Summary
Noroviruses (NoVs), a major foodborne pathogen, accumulate in shellfish via filter feeding. This review explores NoV bioaccumulation, tissue distribution, and binding mechanisms in shellfish, offering insights for risk reduction.
Area of Science:
- Foodborne viral pathogens
- Molecular mechanisms of viral bioaccumulation
- Shellfish aquaculture and safety
Context:
- Noroviruses (NoVs) are a leading cause of foodborne illness globally.
- Shellfish are primary vectors for NoV transmission due to their filter-feeding habits.
- Understanding NoV accumulation in shellfish is crucial for public health.
Purpose:
- To review current research on Norovirus bioaccumulation in shellfish.
- To elucidate the mechanisms of NoV concentration and tissue distribution in shellfish.
- To explore the role of histo-blood group antigens (HBGAs) in NoV binding.
Summary:
- Shellfish concentrate Noroviruses from seawater, with accumulation potentially varying by genotype, season, and location.
- Histo-blood group antigens (HBGAs) in shellfish tissues are implicated in Norovirus binding and accumulation.
- Further research is needed to clarify the detailed mechanisms of Norovirus concentration and bioaccumulation.
Impact:
- Provides a comprehensive overview of Norovirus-shellfish interactions.
- Offers insights into controlling Norovirus transmission through shellfish.
- Aims to reduce the health risks associated with consuming contaminated shellfish.
