  • a Two polymorphisms were observed in HA at positions 1347 and 1499, relative to avian H3N8 sequence CY041887. Isolates from animals earlier in the outbreak showed C at position 1347 and C at position 1499. The variations C1347T and C1499A were observed in animal 295-Pv, in addition to the wild-type sequence. Animal 294-Pv showed only the variant genotype.
