Borrelia burgdorferi Johnson et al. was first isolated from the midgut of Ixodes dammini Spielman et al. in the U.S.A. and from the midgut of I.ricinus (L.) in Europe. I.ricinus was considered to be the only tick vector of this borrelia, in Europe, until I.hexagonus Leach, the hedgehog tick, was found to harbour spirochaetes. This paper reports an evaluation of the vector competence of I.hexagonus for the spirochaete B.burgdorferi. Transovarial and trans-stadial survival were demonstrated and the spirochaete was transmitted to laboratory mice via the bites of trans-stadially infected I.hexagonus females.
伯氏疏螺旋体约翰逊等人最初是从美国达氏硬蜱斯皮尔曼等人的中肠以及欧洲蓖麻硬蜱的中肠中分离出来的。在欧洲，直到发现刺猬硬蜱六足硬蜱利奇携带螺旋体之前，蓖麻硬蜱一直被认为是这种疏螺旋体的唯一蜱传播媒介。本文报告了对六足硬蜱作为伯氏疏螺旋体螺旋体传播媒介能力的评估。证明了经卵和经龄期存活，并且螺旋体通过经龄期感染的六足硬蜱雌性叮咬传播给实验室小鼠。
