title: Characterization of visna virus envelope neuraminic acid.
abstract: 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.
