Abstract
Serological studies (complement-fixation, immunofluorescent and plaque reduction neutralization) were carried out with 50 vertebrate rhabdoviruses to determine their antigenic relationships. On the basis of these studies, an antigenic classification of rhabdoviruses infecting terrestrial vertebrates is proposed. This classification includes three major and four minor serogroups. Several new members of the vesicular stomatitis serogroup were identified.
