摘要证据表明，田鼠Babebrummicroti可能通过提高其蜱虫载体三角硬蜱的喂养成功率和存活率来促进其在啮齿动物中的传播。幼虫蜱虫的平均充血重量和幼虫蜕皮的百分比增加，幼虫喂养幼稚主机后，在寄生虫病周期的一个点几天后，专利感染的损失。这种增加的喂养成功率和存活率不依赖于B的感染水平。显微镜两种可能的，主机介导的机制所观察到的寄生虫-载体的相互作用的建议，巴贝虫病和巴贝虫的免疫抑制作用的相互作用和发展免疫硬蜱的脊椎动物宿主诱导的抗止血作用。
SUMMARY Evidence is presented that Babesia microti may promote its transmission amongst rodents by enhancing the feeding success and survival of its tick vector, Ixodes trianguliceps. Both the mean engorged weight of larval ticks and the percentage moult of larvae to nymphs increased as larvae fed on naive hosts later in the parasitaemic cycle up to a point a few days beyond the loss of a patent infection. This increased feeding success and survival was not dependent on the level of infection by B. microti. Two possible, host-mediated mechanisms for the observed parasite–vector interactions are suggested, the anti-haemostatic effects induced by babesiosis and the interaction of the immunosuppressive effects of Babesia and the development of immunity to ixodid ticks by their vertebrate hosts.
