1985年8月~1986年11月,作者以我国发现的恙螨新种海岛纤恙螨子代幼虫656只,分为21组,叮咬健康小鼠,从子1代到子4代幼虫叮咬过的小鼠中,连续分离出7株恙虫病立克次体,证明海岛纤恙螨能够经卵传递恙虫病立克次体至少4代.同时在该螨的卵、幼虫、若虫、成虫组织细胞内发现有恙虫病立克次体寄生,并发现有分裂增殖形态的立克次体,证明海岛纤恙螨各变态期内均保有恙虫病立克次体,这些立克次体能在恙螨体内大量增殖,连续传代.此项研究结果,对于确认海岛纤恙螨为浙江沿海地区恙虫病的传染媒介和宿主,提供了重要的科学依据.
From August 1985 to November 1986, 656 young larvae of chigger mites were identified as chigger mites in our country. They were divided into 21 groups and bite healthy mice, bites from the first generation to the fourth generation of larvae Of the mice, seven strains of Rickettsia tsutsugamushi were isolated in succession, and it was proved that chigger mites were able to transfer Rickettsia tsutsugamushi for at least 4 generations via eggs. At the same time, eggs, larvae, nymphs and adult cells Rickettsia tsutsugamushi disease was found parasitic and found that there are proliferative morphology of Rickettsia, to prove that during the periostation Island fiber tsutsugamushi disease remain rickettsia, these rickettsia in chigger body A large number of proliferation, continuous passage.The results of this study, to confirm the island chigger mite tsutsugamushi for the coastal areas of Zhejiang vector and host provides an important scientific basis.
