Larvae of Rhipicephalus haemaphysaloides were infected with Kaysanur Forest disease (KFD) virus by feeding on viraemic rodents and reared into next generation larvae. Fed larvae, nymphs, unfed adults, fed adult males, and females after oviposition were found infected, while the larvae were found free from infection. Nymphs and adults transmitted the infection by bite to rodents and rabbits respectively. The virus was also passed through a second rodent-tick cycle. Adult ticks showed a titre of 3.1 to 4.5 dex mouse LD50/0.03 ml, and the virus was also detected 245 days after infection.
通过取食感染基桑努尔森林病（KFD）病毒的带毒啮齿动物，血红扇头蜱幼虫被感染，并发育至下一代幼虫。发现取食后的幼虫、若虫、未取食的成虫、取食后的成年雄蜱以及产卵后的雌蜱均被感染，而幼虫未被感染。若虫和成虫分别通过叮咬将感染传播给啮齿动物和兔子。该病毒还通过第二个啮齿动物 - 蜱虫循环传播。成年蜱的病毒滴度为3.1至4.5对数10小鼠半数致死量/0.03毫升，并且在感染后245天也检测到了病毒。
