Phylogenetic trees of the EBNA1, BZLF1, and LMP1 sequences. Phylogenetic analyses were conducted using MEGA software (version 4) on the basis of multiple alignments of GD1, GD2, AG876, and EBV-WT, the use of rhesus lymphocryptovirus as the outgroup, and the neighbor-joining algorithm. The divergence scale (showing numbers of substitutions per site) is indicated at the foot of each tree.
