General pathology of experimental swine vesicular disease.
Twenty-four minimal disease pigs were inoculated intracerebrally, intravenously or intradermally with an English strain of swine vesicular disease virus. In the skin, snout, tongue and tonsil the main lesion was a full-thickness coagulative necrosis of the stratified squamous epithelium. In the renal pelvis, bladder, tonsillar crypts and the collecting ducts of salivary glands and pancreas, epithelial degeneration with the formation of periodic acid-Schiff-positive material were consistent features of this disease. Histopathological examination alone could not be relied upon to differentiate between well-established skin lesions caused by swine vesicular disease and foot and mouth disease. The relationship between vesicular disease and Coxsackie B5 is discussed briefly.
