HuNoV is the major food-and water-borne virus that accounts for more than 95% of nonbacterial acute gastroenteritis worldwide, but this percentage may be underestimated due to In this study, we developed a highly efficient bioreactor for large-scale production of chicken egg yolk IgY antibodies using rVSV-VP1 as an antigen. Percent of blocking activity was calculated by comparing the OD values measured with or without blocking by the chicken IgYs. As shown in Figure 5 , total IgY antibodies isolated from egg yolks of rVSV-VP1 vaccinated groups were capable of blocking the binding of HuNoV VLP to HBGAs (A, B, or O ./cache/cord-003697-vmmlxr0o.txt ./txt/cord-003697-vmmlxr0o.txt
