Cattle were inoculated with the Fusan strain of the rinderpest virus, and a real-time PCR was developed to examine the amount of excretion of the virus from the feces and the nasal discharge of the cattle. The virus was secreted after 66 hours after the infection, and it was proved that the amount excreted in the feces was twenty times more than that in the nasal discharge by quantitative analysis of the real-time PCR.
