^†, Swabs were randomly taken from six birds in each group and evaluated to quantify virus shedding. Frequency of birds detected with challenge virus is shown in parenthesis and expressed as the number of positive swabs or total number of swabs tested.

^††, Viral copy number is expressed as Mean ± standard deviation (Log₁₀).
