以病毒型啮齿动物为食感染凯萨努尔森林病(KFD)病毒幼虫，并饲养成下一代幼虫。取食的幼虫、若虫、未取食的成虫、取食的成年雄虫和产卵后的雌性幼虫被感染，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。该病毒还经历了第二个啮齿动物-壁虱周期。成虫滴度为3.1~4.5Dex小鼠LD50/0.03毫升，感染后245天仍可检出病毒。
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.
