The lone star tick is common and widespread in the eastern United States and occurs as far north as Maine (Keirans & Lacombe 1998). However, the relatively small number of records from the Park suggests that it is not common there. Immature ticks parasitize a variety of birds and mammals whereas adults typically parasitize larger mammals including humans (Bishopp & Trembley 1945, Strickland et al. 1976, Durden & Kollars 1992). This tick is a vector of Ehrlichia chaffeensis , Ehrlichia ewingii , Rickettsia spp., Coxiella burnetii , and “ Borrelia lonestarii ” a putative agent of southern tick associated rash illness ( STARI) also known as “Lymelike disease” (Childs & Paddock 2003). A new Ehrlichia sp., similar to the agent of heartwater, was recently reported from A. americanum in Georgia (Loftis et al. 2006).
