09年末逻辑狗狗里，那个幼虫的gwd题，能帮解释下吗？

达达1023

顶9楼的，ticks是寄生的，它如果感染一次细菌，其他宿主越多，带lyme的比例越少

1. Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
   
   
   
2. There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice.  诉诸！！
   
   
   
3. A deer tick feeds only once while in the larval stage.    有点像概率， other species population 上升， 则deer tricks feed 到bacteria得几率就下降了
   
   
   
4. A single host animal can be the source of bacterium for many tick larvae.
   
   
   
5. None of the other species on which deer tick larvae feed harbor other bacteria that ticks transmit to humans
