Fig. 5From: Screening and identification of B-cell epitopes within envelope protein of tembusu virusProtective efficacy against TMUV challenge in ducks. Six groups of ducks were inoculated intramuscularly with 104 TCID50 of TMUV. Serum samples were collected daily and inoculated onto BHK-21 monolayer. After 3-day incubation, cell cultures were harvested for detection of TMUV by qPCR. The protection index (PI) was calculated to present protective efficacy of each epitopeBack to article page
