Figure. A) Warthin-Starry–stained section of bat liver showing numerous spirochetes. B) Phylogram inferred from 776-bp alignment of flaB fragments obtained from infected bat liver tissue and for other members of the relapsing fever group of Borrelia species for which sequence data were available. B. burgdorferi is included as an outgroup. The numbers appearing after the names of the Borrelia species are the relevant GenBank accession numbers.
