Figure 2From: Effect of species, breed and route of virus inoculation on the pathogenicity of H5N1 highly pathogenic influenza (HPAI) viruses in domestic ducksStudy 1: virus shedding. Ducks were intranasally inoculated with the Mongolia/09 H5N1 HPAI virus. Oropharyngeal and cloacal swabs were taken from all birds remaining at 3 dpi. For Muscovy ducks, no shedding data was available because all died by 2 dpi.
