Abstract
Purified suspensions of Coxsackie B5 virus and swine vesicular disease virus (SVDV) were prepared by harvesting and purifying cell pack virus. Crossed immunoelectrophoresis was carried out with purified N and H antigen fractions (full and empty particles). Relative migration velocity (RMV) was calculated for the N antigen fraction of 3 SVD viruses (UKG72, HK71 and Italy 66) and 2 Coxsackie B5 viruses (Faulkner and 8068). The prototype strain of Coxsackie B5 virus (Faulkner) had a low RMV almost identical to that of the first isolated strain of SVDV, Italy 66. A recent isolate of Coxsackie B5 virus (8068, isolated in UK in 1973) had a relatively high RMV very close to that of the UKG72 strain of SVDV isolated in the UK in 1972. Also the Hong Kong strain of SVDV (HK71) had a high RMV value. These observations are considered in relation to the emergence of swine vesicular disease.
