摘要: Norovirus is the leading cause of nonbacterial foodborne disease outbreaks. Human noroviruses (HuNoVs) bind to histo-blood group antigens as host receptor for infection. In this study, inhibitory effects fucoidans from brown algae, Laminaria japonica (LJ), Undaria pinnatifida and sporophyll, were evaluated against murine norovirus (MNoV), feline calicivirus (FCV) HuNoV. Pretreatment MNoV or FCV with at 1 mg/mL showed high antiviral activities, 1.1 average log reductions viral titers in plaque assays. They also significant inhibition on binding P domains HuNoV GII.4 GII.17 A- O-type saliva LJ fucoidan was most effective, reaching 54–72% mg/mL. STAT1−/− mice infected MNoV, oral administration fucoidan, composed mainly sulfated fucose minor amounts glucose galactose, improved survival rates significantly reduced their feces. Overall, these results provide can be used reduce NoV
