Characterization of visna virus envelope neuraminic acid.

Visna virus particles inhibit influenza virus hemagglutination in an assay for neuraminic acid-containing viruses. Pretreatment of visna virus with neuraminidase abolished hemagglutination inhibition activity but did not significantly affect attachment, infectivity, or virus-induced cell fusion in sheep choroid plexus cell monolayers.

Murine influenza virus encephalomyelitis. III. Effect of defective interfering virus particles.

Defective interfering influenza virus particles lessened the yield of infective virus recovered from brain after intracerebral challange of 3-week old mice, but failed to affect the appearance of disease or lethality. In 7-week old mice, the presence of defective interfering influenza virus particles reduced both lethality and virus yield. Viral inocula containing significant numbers of defective particles appeared to diminish later inflammatory changes, nerve cell degeneration and the appearance of viral antigen in deeper cerebral regions. The protective effect exerted by defective virus particles does not appear related to interferon production in brain.
