From: Surveillance and characterization of avian-origin H3N2 canine influenza viruses in 2021 in China

  1. Hemagglutinin Inhibition (HI) titers (are the inverse of the highest dilution that inhibited hemagglutination. Cells in black: high titers (≥ 640). Cells in gray: moderate HI titers (160, 320). Low HI titers (40, 80) are not shaded. “ < ”: Titers < 10. †Homologous titer. a Viruses identified previously were selected as reference strains for different HI groups. b Isolated strain
