Summary
Purified African horsesickness virus was shown to possess an icosahedral shape, measure approximately 55mμ in diameter and probably consist of 32 capsomeres. Electron microscopic evidence indicates a close morphological relationship between the virus and bluetongue virions. African horsesickness virus has a double-stranded RNA genome which was resolved into five components by sucrose gradient sedimentation analysis and into six segments in four size groups by means of polyacrylamide gel electrophoresis. The remarkably close relationship between African horsesickness and bluetongue viruses has led to the suggestion that these two viruses be classified in one sub-group of the newly proposed diplorna-virus group.
