[Experimental study of relations of the argasid ticks Alveonasus lahorensis with Coxiella burnetii].
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.
