Figure 1.

Polar tree layout of the phylogenetic relationship of theBorreliaflagellin B (flaB) gene fragment (330 bp) amplified from ticks collected from Arkansas canines and white-tailed deer, and host blood samples^a. Those specimens aligning with B. burgdorferi are highlighted in gray^b. ^a The different tick species are abbreviated A. americanum (Aa), A. maculatum (Am), D. variabilis (Dv), I. scapularis (Is), and R. sangineus (Rs). Ticks from canines (c), ticks from deer (d), and blood samples (Canine or Deer) are also represented. ^bThe different Borrelia species are abbreviated as BL for B. lonestari and BB for B. burgdorferi
