进行了一项研究，以检查变异革蜱体内的细菌，变异革蜱是北美东部落基山斑点热的主要媒介[日期未给出]。在美国印第安纳州的几个地点通过拖拽收集变量。所获得的序列与Arsenophonus、γ-Proteobacteria和Enterobacteriaceae的序列高度相似。系统发育分析表明，与革蜱相关的Arsenophonustype 16 S-rDNA序列形成了一个与其它Arsenophonustype 16 S-rDNA序列相关但又不同的群体（平均差异为0.7）。结果表明，高密度的可能的内共生体在革蜱种群。
A study was conducted to examine bacteria withinDermacentor variabilis, the major vector of Rocky Mountain Spotted Fever in eastern North America [date not given].D. variabiliswere collected by dragging in several locations in Indiana, USA. A significant proportion of sequences obtained were highly similar toArsenophonus, γ-proteobacteria and Enterobacteriaceae family. Phylogenetic analysis of approximately 1349 bp of sequence showed thatDermacentor-associatedArsenophonustype 16S-rDNA sequences form a coherent group (0.7 average divergence) related to, but distinct from otherArsenophonustype microbes. Results indicate high densities of possible endosymbionts inDermacentorpopulations.
