Figure 1. . Phylogenetic trees A) of hemagglutinin (HA) and B) neuraminidase (NA) genes of highly pathogenic avian influenza A (H7N3) virus isolated from a poultry worker with conjunctivitis in Jalisco State, Mexico, July 2012, and other influenza viruses. Reassortant vaccine candidates are shown with a V, and hemagglutinin inhibition (HI) reference viruses used in HI tests are shown with an R in the HA tree. Arrows indicate strain names with V and R. Highly pathogenic avian influenza A(H7N3) viruses from Mexico are indicated in boldface. Trees were midpoint rooted with other North American-lineage H7 HA and N3 NA gene sequences, and subtrees containing ancestral and related viruses were produced. Bootstrap values >60 are shown above or below branches in each tree. *Viruses detected in 2011 or 2012. Scale bars indicate nucleotide substitutions per site.
