为了确定幼虫 Ixodes dammini 是否被莱姆病螺旋体（伯氏疏螺旋体）经卵巢感染，我们扫描了幼虫 I。 dammini 来自美国马萨诸塞州 4 个地区的植被，螺旋体在这些地区流行。允许幼虫以未感染的仓鼠为食。蜕皮至若虫阶段后，对 274 只进行了螺旋体检查。发现两只若虫被感染。经卵巢感染的罕见性（0.7%）表明，经卵巢传代对于维持 B 的重要性有限。 burgdorferiin 性质，但它可能提供一种将螺旋体运输到新地点的机制。
To determine whether larvalIxodes damminiare infected transovarially by Lyme disease spirochetes (Borrelia burgdorferi), we swept larvalI. damminifrom vegetation in 4 regions of Massachusetts, USA, where the spirochetes are endemic. Larvae were permitted to feed on noninfected hamsters. After molting to the nymphal stage, 274 were examined for spirochetes. Two nymphs were found to be infected. The rarity of transovarial infection (0.7%) suggests that transovarial passage is of limited importance in maintainingB. burgdorferiin nature, but that it may provide a mechanism for transporting spirochetes to new sites.
