RESUMO
A method for obtaining large quantities of defective interfering (DI) rabies virus particles that fulfill all the criteria delineated by Huang and Baltimore (1970) is described. The purified rabies DI virion was found to be much shorter (60 to 80 nm) than the complete virion (180 nm) and to have a viral genome of about half the size of normal rabies RNA but with all of the structural proteins of standard virions. Rabies DI virions were noninfectious for both cells in culture and for animals. As determined by in vitro and in vivo techniques, interference with the replication of standard virus was specific to rabies virus. The possible role of rabies DI virion in the pathogenicity of rabies virus infection and in the establishment of attenuated strains for use as live rabies vaccines is discussed.
