Pigs which are serologically positive for swine vesicular disease virus (SVDV) but which show no clinical signs and for which there is neither a relevant history of the disease on the holding nor contact with a known outbreak are considered as singleton reactors. False positive serological results for an epizootic disease, like SVD, in a non-vaccinated population or in imported animals are of great concern to international trade. For the virus neutralisation test, the gold standard for SVD, singleton reactors are found at a level of 1-3/1000. Singleton reactors also occur when other serolog…
