Human rotaviruses (Wa, KUN, MO) showed hemagglutination (HA) only with fixed 1-day-old chicken erythrocytes, and their HA activities were completely destroyed by trypsin activation of virions. Simian SA-11 and bovine NCDV had HA activities not only against fixed erythrocytes but also against fresh erythrocytes from various species. Their HA activities against fixed erythrocytes were also inhibited by trypsin activation, but those against fresh erythrocytes were not. Neuraminidase treatment of fixed erythrocytes did not inhibit HA by trypsin-untreated rotaviruses. In contrast, HA of fresh human erythrocytes by SA-11 and NCDV was completely inhibited by neuraminidase treatment of erythrocytes or glycophorin A, the major erythrocyte sialoglycoprotein. Adsorption and infection of SA-11 and NCDV to monkey kidney MA104 cells were also inhibited by neuraminidase treatment of cells. Adsorption and infection of human rotavi-ruses were not, however, affected by treatment of cells with neuraminidase from Vibrio cholerae or Arthrobacter ureafaciens or with potassium periodate. Therefore, HA of fixed chicken erythrocytes by trypsin-untreated human and animal rotaviruses may be independent of sialic acids, whereas that of fresh erythrocytes by SA-11 and NCDV is sialic acid dependent and probably mediated by glycophorin A. Sialic acids also constitute an essential part of the cellular receptors for SA-11 and NCDV, whereas those for human rotaviruses were quite resistant to treatments known to destroy major types of siallc acids.
