The argasid ticks A. lahorensis can be infected with Coxiella burnetii on feeding on an infected rabbit. The adoptive pathogen reproduces in the ticks and accumulates in them up to 10(10) ID50 g(-1). Coxiella persists in the ticks at this level up to 156 days (the time of observation). The infected ticks transmit Coxiella to guinea pigs while sucking. The ticks show transovarial transmission of Coxilla during metamorphosis. On this basis and with consideration for the fact that A. lahorensis uses a wide host range, it can long starve and retains Coxiella burnetii in the foci of Q fever.
钝缘蜱属的拉合尔钝缘蜱在吸食感染兔血液时可感染伯氏考克斯体。被感染的病原体在蜱体内繁殖，并在蜱体内累积至每克10¹⁰半数感染剂量（ID50）。在长达156天（观察期）的时间内，伯氏考克斯体在蜱体内维持此水平。受感染的蜱在吸血时将伯氏考克斯体传播给豚鼠。蜱在变态发育过程中呈现伯氏考克斯体的经卵传播。基于此，并考虑到拉合尔钝缘蜱宿主范围广泛、可长期饥饿且在Q热疫源地中保留伯氏考克斯体这一事实。
