Isolation and Genetic Characterization of the Human Relapsing Fever Spirochete Borrelia persica from a Dog with Improved Cultivation Techniques

Figure 6

Maximum likelihood phylogram comparing 407-bp DNA fragment sequences of the Borrelia 16S rRNA gene from the canine blood and cultured B. persica strain included in the study to sequences of other B. persica and Borrelia species (GenBank accessions). New sequences derived from this study are marked with black diamond squares. The GenBank accession numbers, species of infected host, and country of origin are included for each sequence. The Kimura-2-parameter model was used in the construction of this phylogram with bootstrap performed on 1,000 replicates.
