The ability of rabbit hemorrhagic disease virus to agglutinate
human erythrocytes and to attach to rabbit epithelial cells of the
upper respiratory and digestive tracts was shown to depend on the
presence of ABH blood group antigens. Indeed, agglutination was
inhibited by saliva from secretor individuals but not from nonsecretors, the latter being devoid of H antigen. In addition, erythrocytes of the rare Bombay phenotype, which completely lack ABH
antigens, were not agglutinated. Native viral particles from extracts
of infected rabbit liver as well as virus-like particles from the
recombinant virus capsid protein specifically bound to synthetic A and
H type 2 blood group oligosaccharides. Both types of particles could
attach to adult rabbit epithelial cells of the upper respiratory and
digestive tracts. This binding paralleled that of anti-H type 2 blood
group reagents and was inhibited by the H type 2-specific lectin UEA-I
and polyacrylamide-conjugated H type 2 trisaccharide. Young rabbit
tissues were almost devoid of A and H type 2 antigens, and only very
weak binding of virus particles could be obtained on these tissues.
