(The larval burdens (A) and nymphal burden (B) of mice were significantly repeatable across multiple capture events such that mice with high tick burdens in one observation had high tick burdens at subsequent captures. These data indicate that ticks were aggregated on a consistent subset of mice throughout the larval and nymphal activity seasons.)
