Chicken endothelial cells are more infected than duck endothelial cells by HPAI virus infection. Representative FACS plots showing the number of cells positive for viral antigen 24 h after inoculation with A/turkey/Turkey/1/05 (H5N1). Cells were initially gated on their FSC-A/SSC-A profile. Mock infected cells of each species/cell subtype were then used to define the position of the relevant influenza virus antigen positive gate
