Figure 3From: High genotypic diversity and a novel variant of human cytomegalovirus revealed by combined UL33/UL55 genotyping with broad-range PCRPhylogenetic analysis of UL33 genotypes. UL33 proteins (Figure 4) were aligned to construct a phylogenetic tree using the Neighbor-joining method. A rooted phylogram is shown, with the UL33 of the chimpanzee cytomegalovirus CCMV as outlier. The branch length is proportional to evolutionary distance (scale bar). Results of bootstrap analysis (1000 replicates) are indicated at the nodes of the tree.Back to article page
