Abstract

Virolactias as a result of foot-and-mouth disease infection in dairy cattle would indicate active virus replication in the bovine mammary gland. In the present study, virus was readily detected throughout the mammary gland by infectivity assay after cows were exposed to the virus either by aerosol or by a combination of intramammary-IV inoculation. Furthermore, immunofluorescent and hematoxylin and eosin staining of alternate frozen sections showed viral antigens in rounded alveolar cells with pyknotic nuclei.
