Abstract excerpt

Amino acid and phylogenetic analysis showed that PB1-F2 of H7N7 and H3N8 equine influenza virus (EIV) evolved into two and nine clades, respectively. The PB1-F2 gene of H7N7 EIV strains isolated after 1973 was identified as being replaced by that of H3N8 EIV circulating simultaneously. All H7N7 EIV strains before 1973 contained PB1-F2 of 34 aa, while 90 aa after 1973. Meanwhile, most H3N8 EIV strains contained...
