摘要: 本实验首次证实全沟硬蜱可经卵传递伯氏疏螺旋体,2只卵巢感染螺旋体的雌蜱的子代感染率分别为59%和29%。伯氏疏螺旋体主要分布于全沟硬蜱的中肠内,饥饿和饱血蜱的中肠感染率相近,分别为30.9%和29.0%:而两者的全身感染与中肠感染之比则分别为2.9%和15.0%。

Abstract: Transovarial transmission of Borrelia burgdorferi in Ixodes persulcatus was found for the first time. The filial larval infection rates of two females with ovary infection were 59% and 29%, respectively. The spirochetes were found mainly in the midgut of adult I persulcatus. Although the midgut infection rates of the starved and engorged ticks were similar ( 30.9% and 29.0% ) , the systemic infection rates of the starved and engorged infected ticks were 2.9% and 15.0%, respectively.
