Diseases to be considered in the differential diagnosis of foot-and-mouth disease are reviewed. The main aspects relating to the diagnosis of vesicular stomatitis, bovine virus diarrhea, malignant catarrhal fever, bovine herpesvirus 1 and 5, andem ulcerative stomatitis associated with bovine parvovirus are described. Bluetongue, that probably occurs in Rio Grande do Sul because antibodies to the virus have been detected in cattle and sheep; is refered. Bovine ulcerative mammilitis, reported in other Brazilian States, rinderpest, reported and eradicated in the State of São Paulo in 1921, and popular stomatitis are also cited, and so are two exotic diseases: vesicular exanthema and swine vesicular disease.
