RESUMO
Swine vesicular disease (SVD) is a notifiable viral disease of pigs included on the Office International des Epizooties List A. The first outbreak of the disease was recognized in Italy in 1966. Subsequently, the disease has been reported in many European and Asian countries. The causative agent of the disease is SVD virus which is currently classified as a porcine variant of human coxsackievirus B5 and a member of the genus enterovirus in the family picornaviridae. From a clinical point of view, SVD is relatively unimportant, rarely causing deaths and usually only a minor setback to finishing schedules. However, the clinical signs which it produces are indistinguishable from those caused by foot-and-mouth disease, and its presence prevents international trade in pigs and pig products. This article reviews recent findings on all aspects of the virus and the disease which it causes.

Tests for associated immunization of swine against Foot and Mouth Disease (FMD) and Vesicular Disease (SVD) of swine were carried out. As a result of this investigation, it was established that the prepared and tested inactivated oil vaccine is harmless and immunogenic in sensitive animals. In investigating the course of immunity, the presence of antibody against both antigens was demonstrated in vaccinated animals. All once-vaccinated animals were defended against the virus of SVD during challenge, and 75% of them were defended against FMD. After revaccination, all immunized swine were defended against infection with both viruses. The question of the quality of the associated vaccine and the possibilities of its massive use in industrial swine rearing was discussed.
