Per os infectivity of white spot syndrome virus (WSSV) in white-legged shrimp ( Litopenaeus vannamei ) and role of peritrophic membrane

This study indicated that WSSV contaminated feed is poorly infectious via peroral route, whereas it is highly infectious when injected into shrimp. The PM plays a minor role as internal barrier of shrimp against WSSV infection.
