Some species, such as lizards, are referred to as “dilution hosts” because they don’t tend to support Lyme disease pathogens and so decrease the likelihood that the disease will be passed on by ticks feeding on them. White-tailed deer are both a food source and a “reproductive host”, where ticks tend to mate. The white-footed mouse is a reservoir host in which the pathogen for Lyme disease can survive.
