Abstract:
... White spot syndrome virus (WSSV) is an extremely destructive virus in shrimp farming which has caused a serious economic loss to global shrimp industry. Learning its infection routes is the basis for WSSV prevention and control. The digestive tract and gill were generally considered to be the target tissues for WSSV entry into shrimp. However, whether there is any other target tissue for WSSV entr ...
