Abstract excerpt
Influenza A viruses were isolated in Vero, MDCK cells and chicken embryos. In contrast to MDCK-derived variants all H3N2 isolates obtained in Vero cells neither agglutinated chicken erythrocytes nor grew in chicken eggs. These host range differences of H3N2 Vero and MDCK isolates were noticed even in the absence of amino acid substitutions in the HA1 molecule. Evaluation of HA glycosylation pattern by treatment...
