Figure 2. Phylogenetic analysis of the partial hexon and fiber genes of HAdV-56 in this outbreak by the neighbor-joining method.

(A) Phylogenetic tree based on the partial hexon gene of the HAdV-56 Liaoning 2012-01∼36H strains and reference strains of other common HAdVs that cause EKC. (B) Phylogenetic tree based on the partial fiber gene of the HAdV-56 strains (Liaoning 2012-12, 14, 18, 22 and 34F) and reference strains of other common HAdVs that cause EKC.
