  1. Significant differences among locations are noted with superscript letters; a and b denote differences among adults, c and d denote differences among nymphs. Proportions in each column sharing different.
  2. Superscripts were significantly different (p < 0.017). Those proportions in each column wth the same superscript were not significantly different. The absence of a superscript indicates no significant difference.
  3. A.p., Anaplasma phagocytophilum; Ba.m., Babesia microti; B.b., Borrelia burgdorferi; EML, Ehrlichia muris-like agent.
