比较了从地方性啮齿动物中自然产生的受螺旋体感染的蓖麻黄粉虫的丰度，以确定中欧一系列地方性疫点莱姆病病原体的储存宿主。黑条纹小鼠似乎是扁虱最重要的啮齿动物宿主，感染伯氏疏螺旋体的扁虱比测试的其他小鼠和田鼠更多。虽然啮齿类动物感染了大约一半以它们为食的扁虱，但蜥蜴不会感染任何动物。这些不能寄生螺旋体的宿主稀释了传播力，因为许多若虫以它们为食。年龄较大的雄性寄主比年轻或雌性寄主更容易感染亚成虫。莱姆病病原体在中欧特定地点的传播强度似乎与黑条纹老鼠的存在直接相关，与蜥蜴的存在相反。
The abundance of spirochete-infectedIxodes ricinusticks naturally derived from endemic rodents was compared to identify the reservoir hosts of the agent of Lyme disease at a series of enzootic sites in Central Europe. Black-striped mice appear to be the most important rodent host for the tick and infect more ticks withBorrelia burgdorferithan do other mice and voles tested. Although rodents infect about half of the ticks that feed on them, lizards infect none. These spirochete-incompetent hosts dilute the force of transmission because many nymphal ticks feed on them. Older male hosts are more heavily infested by subadult ticks than are younger or female hosts. The intensity of transmission of the agent of Lyme disease at particular Central European sites appears to correlate directly with the presence of black-striped mice and inversely with that of lizards.
