FIG. 2.

Comparison of parsimony tree (left side) and neighbor-joining tree (right side) derived from complete ITS sequences for recognized Bartonella species (type strains). The support of each branch, as determined from 100 bootstrap samples, is indicated by the value at the node. The lengths of vertical lines are not significant. For the parsimony tree, the lengths of horizontal lines are also not significant. For the neighbor-joining tree, the scale bar represents evolutionary distance as calculated by using the Kimura two-parameter distance calculation.
