The recognized range of the Gulf Coast Tick, Amblyomma maculatum has increased in recent years.  In 2012, notable numbers of Amblyomma maculatum and Dermacentor variabilis ticks were collected from West-Central Kentucky and Northern Tennessee. During this survey we found that 14.3% of Amblyomma maculatum were infected with Rickettsia parkeri (15 of 105) and 3.3% of Dermacentor variabilis were infected with Rickettsia montanensis (10 of 299). These findings warrant regional elevated public health awareness for rickettsial disease.
