为了明确长角血蜱、草原革蜱在我国北方莱姆病传播中的地位和作用 ,以全沟硬蜱为对照 ,在实验室内对它们经期传播莱姆病螺旋体的可能性进行了研究。结果表明 ,全沟硬蜱可保持活的螺旋体到下一发育阶段 ,并且其体内的莱姆病螺旋体具备感染敏感KM鼠的能力。长角血蜱和草原革蜱虽然可以通过吸血获得莱姆病螺旋体 ,但它们对莱姆病螺旋体的保持期较短 ,不能跨越蜕皮阶段 ,因而不具备经期携带、传播的能力。所以它们作为莱姆病媒介的可能性不大。在长角血蜱或草原革蜱体内检测到的莱姆病螺旋体可能是它们与全沟硬蜱共同吸血的原因所致 In order to clarify the status and role of Erysiphe graminicum in the transmission of Lyme disease in the north of China, the possibility of transmitting Lyme disease in its laboratory was studied in the laboratory with Ixodes rubra as a control. The results showed that I. ipsiflora maintained the viable spirochete to the next developmental stage, and its Lyme disease spirochete possessed the ability to infect susceptible KM mice. Although they can obtain Borrelia burgdorferi by sucking blood, they have a short retention period for Borrelia burgdorferi and can not cross the molting stage, so they do not possess the ability to carry and transmit during menstruation. So they are unlikely to be Lyme disease vectors. The detection of Borrelia burgdorferi in B. longicornis or B. graminicola may be due to their co-occlusion with I. ipsilon
