Technical Abstract: The early responses of the innate host defense are dedicated to the containment of pathogens, holding infections to a level that can be resolved by the ensuing acquired immune mechanisms. Toll-like receptor (TLR) family members are responsible for initiation of the innate immune response. In particular, TLR7 has been shown to respond to ssRNA viral genomes. To explore the differences in innate immune responses between chickens and ducks, sequence analysis of TLR7 was performed and compared with cytokine induction following highly pathogenic AI infection. Differences in the TLR7 gene and cytokine responses were observed between chickens and ducks.
