Summary data (means ± standard error) for body weight (grams), tick burden (number of ticks per mouse) and the proportion of Peromyscus leucopus mice infected with Borrelia burgdorferi are shown for the six combinations of sex and stage (juvenile, subadult, and adult). The sample size (n) was calculated across all years and areas of the study.
