Virus titers in tissues from Pekin ducks and Chinese geese directly inoculated or contact-exposed with H5N8 and H5N2 HPAI viruses. Titers determined by qRRT-PCR. A Tissues from Pekin ducks, 4 dpi. B Tissues from geese, 4 dpi. C Tissues from geese showing neurological signs euthanized at 8 dpi and 10 dpi inoculated or exposed to H5N2 virus, respectively. Bars represent the standard error of the mean. Tissues from which virus was not detected were given a numeric value of 101.7 EID50/g.
