Absence of swine vesicular disease from Switzerland: results of a sero-epidemiological survey using ELISA (1985-1987)
نویسندگان
چکیده
Since there has been no evidence of swine vesicular disease (SVD) in Switzerland since 1973, and because the disease can circulate in an inapparent form, a sero-epidemiological survey was undertaken. For this purpose, an ELISA was developed, using a cytoplasmic extract from infected and uninfected cell cultures. This extract was later analysed by PAGE and immunoblotting, and was shown to contain the structural viral proteins VP0, VP1, VP2, VP3 and VP4.

Swine vesicular disease (SVD) is a highly contagious viral disease that causes vesicular disease in pigs. The importance of the disease is due to its indistinguishable clinical signs from those of foot-and-mouth disease, which prevents international trade of swine and related products. SVD-specific antibody detection via an enzyme-linked immunosorbent assay (ELISA) is the most versatile and com...

From 1996 to 1999, blood samples were collected from wild boar shot during the hunting season in Crown properties, national parks and the free wildlife belt in the Netherlands. Sera were screened for the presence of antibodies against classical swine fever virus (CSFV), swine vesicular disease virus (SVDV), Aujeszky's disease virus (ADV) and Trichinella spiralis. The results of the sero-surveil...
