Figure 3. Evolutionary relationships of Chiloé Island sample compared with other isolates of Orientia tsutsugamushi, with O. chuto sp. nov. and with taxa from Rickettsia, determined by the method of neighbor joining (15). The tree is drawn to scale; scale bar indicates nucleotide substitutions per site. Numbers on branches represent percentage of 1,000 bootstrap replicates that include the enclosed clade. Entries on the tree are identified by GenBank accession number and isolate name.
