Tissues collected at 2 days postchallenge were homogenized to a 10% (wt/vol) final concentration. Tenfold dilutions of the 10% homogenates (100 μl) were inoculated into 10-day-old embryonated chicken eggs (ECE), and virus titers were calculated. The threshold of detection was 101.9 EID50/g of tissue.
