Phylogenetic analysis of HAdV: (a) the entire hexon gene (nt 18255 to 21101, Slobitski strain), (b) the 5′ end of the partial hexon gene covering HVRs 1 to 7 (nt 18361 to 19801, Slobitski strain), and (c) the 3′ end of the partial hexon gene outside the HVRs (nt 19802 to 21101, Slobitski strain). The phylogenetic tree was generated by using the neighbor-joining method; bootstrap values are provided for the basal nodes of each species (species A to G). The GenBank accession numbers for each HAdV are as follows: HAdV-12, X73487; HAdV-31, DQ149611; HAdV-3, X76549; HAdV-7, AF515814; HAdV-11a, AY972815; HAdV-11p, AF532578; HAdV-14, AY803294; HAdV-21, AY008279; HAdV-34, AB052911; HAdV-35, AB330116; HAdV-50, DQ149643; HAdV-2, AJ293903; HAdV-5, AF542130; HAdV-17, AB330098; HAdV-48, U20821; HAdV-4, AF065063; HAdV-40, X51782; HAdV-41, AB330122; and HAdV-52, DQ923122. Strain HAdV11-QS could definitely be identified as an HAdV-11a strain belonging to the B2 species, but recombination with the sequence of HAdV-14 was found at the 3′ end of the hexon gene.
