从携带螺旋体的O型开始turicata [雌性]从自然界收集的蜱饲养，对5个连续世代中每一个的1个[雌性]（在1个实例中3个[雌性][雌性]）第一次产卵产生的后代进行螺旋体定量测试。除注明的例外情况外，所有试验均通过在白色小鼠的每个发育阶段单独饲喂蜱进行。采用厚滴法和Giemsa染色法。在5个世代中，每一个世代中发现的感染性后代分别为6只蜱（35%）、55只蜱（96%）、66只蜱（100%）、107只蜱（47%）和136只蜱（100%）。在近6年的时间里，螺旋体的侵袭力没有减弱。在检查的第1天和喂养后的第5天，它们出现在所有F5代宿主小鼠的外周血中。这些结果表明，蜱本身可能是一个更有效的“螺旋体水库”比啮齿类宿主。
Beginning with a spirochete-bearing O. turicata [female] reared from ticks collected in nature, the progeny resulting from the first oviposition by 1 [female] (in 1 instance 3 [female][female]) of each of the 5 succeeding generations were tested quantitatively for spirochetes. With exceptions noted, all tests were made by feeding the ticks individually, in each developmental stage, on white mice. The thick drop and Giemsa''s method of staining were used. Progeny found to be infective in each of the 5 generations amounted to 6 ticks (35%), 55 ticks (96%), 66 ticks (100%), 107 ticks (47%), and 136 ticks (100%), respectively. The invasiveness of the spirochetes did not diminish over a period of nearly 6 yrs. They appeared in the peripheral blood of all mice which were hosts to the F5 generation on the 1st day of examination, and the 5th day after feeding. These results indicate that the tick itself may be a more efficient "spirochetal reservoir" than the rodent host.
