Envelope glycoprotein determinants of increased fusogenicity in a pathogenic simian-human immunodeficiency virus (SHIV-KB9) passaged in vivo.

abstract：:The relationship between the vaccinia virus hemagglutinin and hemadsorption was examined. Hemagglutinin synthesis was temporally related to the appearance of the hemadsorption reaction. Only chicken erythrocytes, which reacted with hemagglutinin, hemadsorbed to infected cells, and both of these reactions were inhibite...
