“Background Lyme disease is a multisystemic zoonotic disease caused by Borrelia burgdorferi sensu lato (B. burgdorferi s. l.). B. burgdorferi s. l. circulates in an enzootic cycle between the primary vertebrate reservoir and the ticks[1, 2]. A wide range of mammals are severeded as reservoir hosts in the natural cycle of B. burgdorferi sensu lato[3, 4]. Different species of rodents, mainly mice and voles, are identified to be efficient natural reservoirs for B. burgdorferi sensu lato. They could naturally infect B. burgdorferi sensu lato and remain infective for a long time.
