Figure 2. . Multibasic cleavage sites of highly pathogenic avian influenza (HPAI) A(H7N3) virus isolated from a poultry worker with conjunctivitis in Jalisco State, Mexico, July 2012, and other influenza viruses. Box indicates novel amino acid cleavage site sequence motif. HA, hemagglutinin; LPAI, low pathogenicity avian influenza. Hyphens indicate gaps in the sequence alignments whereby 1 sequence has an insertion of amino acids relative to shorter sequences.
