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

<div>A maximum likelihood phylogram comparing 706-bp DNA fragment sequences of the <i>flaB</i> gene from the canine blood and cultured <i>B. persica</i> strain included in the study to other <i>B. persica</i> sequences and <i>Borrelia</i> spp. (GenBank accessions). New sequences derived from this study are marked with black diamonds. Note the devision of <i>B. persica</i> genotypes marked in Roman numerals. The GenBank accession numbers, species of infected host, and country of origin are included for each sequence. The Tamura-3-parameter model was used in the construction of this phylogram with bootstrap values deduced from 1,000 replicates, and values higher than 70% are indicated.</div>
