ABSTRACT
To identify substitutions that are possibly associated with the adaptation of avian-origin H10N7 virus to mammals, adaptation of the H10N7 virus in mouse lung was carried out by serial lung-to-lung passage. Genomic analysis of the mouse-adapted virus revealed amino acid changes in the PB2 (E627K), PA (T97I), and HA (G409E) proteins, and this virus was more virulent in mice than the wild-type virus. Our results suggest that these substitutions are involved in the enhancement of the replication efficiency of avian-origin H10N7 virus, resulting in severe disease in mice. Continued poultry surveillance of these substitutions in H10N7 viruses is required.
