在与牛流行性流产有关的软蜱--革蜱（Ornithodoros coriaceus）的所有三个寄生阶段中均检测到类阿氏螺旋体。在分离出螺旋体后，根据其形态、蛋白质成分和不能感染小鼠的特性，确定了它与其他北美蜱传疏螺旋体以及与金黄色螺旋体、苍白密螺旋体和波摩那型问号钩端螺旋体的区别。螺旋体通过蜱虫的卵传播，在蜱虫进食和分离后，螺旋体也会分泌到基节液中。间接证据表明，螺旋体可能与流行性牛流产有因果关系。
ABorrelia-like spirochete was detected in all three parasitic stages ofOrnithodoros coriaceus, the soft tick implicated in the epizoology of epizootic bovine abortion. After the spirochete had been isolated, its distinctness from other North American tick-borne borreliae as well as fromSpirochaeta aurantia,Treponema pallidum, andLeptospira interrogansserovar pomona was established on the basis of its morphology, protein components, and inability to infect mice. The spirochete is passed trans-stadially and via eggs by ticks, and it is also excreted in coxal fluid after ticks have fed and detached. Circumstantial evidence suggests that the spirochete may be causally related to epizootic bovine abortion.
