Maximum-likelihood trees of the full-length fiber (A), E1A (B), and hexon (C) open reading frames of adenovirus B2 subgenera. Phylogenetic analysis was performed by using reference sequences from GenBank for the adenovirus B2 subgenera, including prototype reference strains. The query sequences from this study are identical and are represented in boldface. The tree was built in PAUP* (23) on the basis of the HKY85 model of evolution and for the fiber tree also with a β distribution and used midp
