Inocula doses expressed as Log10EID50/100µl. No bird inoculated with lower viral titers became infected based on viral excretion and seroconversion (not shown).
Ct values are from RT-PCR analyses using avian influenza H5 specific primers and probe. Samples with no Ct values are shown with -.
Indicates that RT-PCR positive cloacal swabs were detected on the DPI shown.
Presence of viable virus confirmed by virus isolation in embryonating egg culture.
