Well, I mean I especially worry about deer ticks because they carry Lyme disease.

刘易斯：嗯，我的意思是我特别担心鹿蜱，因为它们携带莱姆病。

Lyme disease is primarily caused by a bacterium called Borrelia burgdorferi, which is transmitted by the bite of the blacklegged tick—more commonly known as the deer tick.

莱姆病主要由一种名为伯氏疏螺旋体的细菌引起，这种细菌通过黑腿蜱（通常称为鹿蜱）的叮咬传播。
