Survival percentages (a), viral excretion (b) and viral tropism (c) after 10⁶ EID₅₀/bird AOAV‐1/Bassette_Chicken/Belgium/4096/2018 inoculation of both infected and sentinel birds. Viral titres are expressed as log₁₀(number of viral RNA copies/ml). Statistical significance is indicated with * (p < .05). Swabs (b) were taken at 1, 2, 3, 7 and 9 dpi, while organs (c) (lung/trachea, intestine and brain) and feathers were sampled at the time of death or at 14 dpi on the day of killing. The surviving sentinel bird is identified with an open triangle (∆) in b and c
