FIG. 1.

Dendrogram representing phylogenetic relationships between Bartonella species. The tree is derived from the concatenated sequences of ITS, 16S rDNA, and the gltA, groEL, rpoB, ftsZ, and ribC genes. The MEGA 2.1 software (http://www.megasoftware.net) was used to infer the tree, by using the neighbor-joining method with Kimura-2 and Jukes-Cantor parameters. The support of each branch, as determined from 1,000 bootstrap samples, is indicated by the value at the node when it is at least 90%. For sequence accession numbers, see Table 2 and reference 10.
