The S1 protein of GA13 differs significantly from that of the Pennsylvania nephropathogenic strains via three insertions. We investigated the influence of specific amino acids on the binding of the S1 proteins to different tissue types, which may explain the differences in pathogenicity between respiratory and nephropathogenic strains of IBV.
