1964年我们在四川省重庆地区自然界捕捉的铃头血蜱首次分离出Q热立克次体,并对该毒株的抗元性进行了研究。鉴于该蜱在国内分布较为普遍,为进一步了解铃头血蜱对Q热立克次体的易感性,探讨其在Q热疫源及流行病学上的意义,特以铃头血蜱为对象,在实验条件下,观察蜱对Q热立克次体的易感性、已感染的蜱叮刺健康动物能否传播、立克次体在蜱体内的储存时间、蜱粪污染情况及病源体经卵、经期传递等问题,进行了实验研究。
In 1964, we isolated the first generation of T. rickettsis in the genus Q. obscurus caught in the natural world of Chongqing in Sichuan Province, China. The anti-metagenicity of this strain was also studied. In view of the distribution of the ticks is more common in the country, in order to further understand the susceptibilities of T. gondii to T. gondii and to explore its significance in the Q epidemic and epidemiology, , Under the experimental conditions, to observe the susceptibility of ticks to the fever of Q Rickettsia, has infected ticks sting health animals can be transmitted, Rickettsia tick body storage time, tick faecal contamination and pathogen body Eggs, menstrual transmission and other issues, conducted an experimental study.
