Figure 3From: Infectivity, transmission and pathogenicity of H5 highly pathogenic avian influenza clade 2.3.4.4 (H5N8 and H5N2) United States index viruses in Pekin ducks and Chinese geese Mean oropharyngeal (OP) and cloacal (CL) viral shed from 2-week-old Pekin ducks directly inoculated (A, C, E, G) or contact-exposed (B, D, F, H) with H5N8 and H5N2 HPAI viruses. Ducks were inoculated with 102, 104 and 106 EID50 of either virus and titers determined by qRRT-PCR. Bars represent the standard deviation of the mean. Swabs from which virus was not detected were given a numeric value of 101.7 EID50/mL.Back to article page
