Infectious YHV was demonstrated in all the tissues and organs tested; inoculation of each of the tissue and organ filtrates into experimental shrimp resulted in 100% mortality within 6 to 9 d postinfection. The TCID50 assay in primary Oka organ cells revealed that Oka, gill and HST contained 10- to 800-fold higher titers of YHV than the other tissues and organs tested and suggested that they are apparently the primary target tissues and organs for YHV infection.
