  1. 6-week-old BALB/c mice were infected intranasally with 104 EID50 of each virus in a 50 μL volume. Organs were collected on days 3 and 6 post-inoculation, and clarified homogenates were titrated for virus infectivity in eggs at initial dilution of 1:10 (lung), 1:2 (other tissues), or undiluted if negative at the lowest dilution.
  2. dpi: days post-infection.
