The Ri chickens resistant or susceptible to HPAIV-H5N1 infection used in this study were provided by the National Institute of Animal Science (NIAS, Hanoi, Vietnam). For H5N1 infection, 4-week-old mixes of male and female chickens (five chickens per group) were infected intranasally with the harvested allantoic fluid from infected eggs, which contained 1 × 104 50% egg infectious dose (EID50) of A/duck/Vietnam/QB1207/2012 (H5N1) [13]. Lung tissues were collected 3 days after infection.
