The shedding of a virulent Kabete O strain of rinderpest virus by cattle.

A Muguga substrain of the virulent Kabete O strain of rinderpest virus was demonstrated in the ocular, nasal, oral and rectal swabs collected from infected cattle. Ocular shedding was detected at the onset of viraemia and before the onset of clinical signs whilst virus shedding in nasal, oral and rectal discharges appeared at the same time as lesions. It is suggested that virus isolation from ocular and nasal swabs should be considered in the diagnosis of rinderpest in addition to the other methods currently employed, as virus was isolated from swabs collected from dead animals.
