已对硬蜱传播性脑炎复合体的几种病毒进行了传代研究。俄罗斯工作人员报告说，俄罗斯春夏脑炎病毒可以在全硫硬蜱、蓖麻硬蜱、森林革螨和康宁血蜱中通过卵巢传播。在捷克斯洛伐克，Benda2研究了蓖麻硬蜱和欧洲硬蜱脑炎病毒株，发现只有6%的硬蜱发生了经卵巢传播，而苏联的Smorodintsev3报告说，这种传播发生在5%-25%的硬蜱中。在一项调查中，Rehacek4证实了硬蜱脑炎病毒在蓖麻黄单胞菌中的经卵传播，发现2%的被喂食感染的扁虱和20%的被喂食后接种的扁虱发生了这种传播。这里报道了该复合体的第三个成员--凯萨努尔森林病病毒及其媒介刺血丝虫的实验室研究。
TRANSOVAJRIAJL passage in ticks has been investigated for several viruses of the tick-borne encephalitis complex. Russian workers have reported that Russian spring–summer encephalitis virus can pass transovarially in Ixodes persulcatus, I. ricinus, Dermacentor silvarum and Haemaphysalis concinna1. Benda2, working with Ixodes ricinus and the European strain of tick-borne encephalitis in Czechoslovakia, demonstrated transovarial transmission in only 6 per cent of ticks, while Smorodintsev3 in the U.S.S.R. reported that it occurred in 5–25 per cent of ticks. In an investigation confirming transovarial transmission of tick-borne encephalitis virus in I. ricinus, Rehacek4 found that it occurred in 2 per cent of ticks infected by feeding and in 20 per cent of ticks infected by inoculation after feeding. Laboratory studies with a third member of the complex, Kyasanur forest disease virus, and its vector Haemaphysalis spinigera are reported here.
