We conducted a survey to describe infection prevalence of tick-borne pathogens in <jats:italic>Amblyomma americanum<\/jats:italic> and <jats:italic>Dermacentor variabilis<\/jats:italic> ticks collected in Kentucky. During 2007\u20132008, we collected 287 ticks (179 <jats:italic>D. variabilis<\/jats:italic> and 108 <jats:italic>A. americanum<\/jats:italic>) from canine, feral hog, horse, raccoon, white-tailed deer, and human hosts in six counties in Kentucky. Ticks were screened for <jats:italic>Rickettsia<\/jats:italic> spp., <jats:italic>Borrelia<\/jats:italic> spp., <jats:italic>and Ehrlichia<\/jats:italic> spp. by using polymerase chain reaction. Forty-one (14.3%) ticks (31 <jats:italic>A. americanum<\/jats:italic> and 10 <jats:italic>D. variabilis<\/jats:italic>) were polymerase chain reaction\u2013positive for a <jats:italic>Rickettsia<\/jats:italic> spp. Fourteen (4.9%) ticks (6 <jats:italic>A. americanum<\/jats:italic> and 8 <jats:italic>D. variabilis<\/jats:italic>) were positive for <jats:italic>E. chaffeensis<\/jats:italic>, and 4 <jats:italic>A. americanum<\/jats:italic> (1.4%) were positive for <jats:italic>E. ewingii<\/jats:italic>. One (0.4%) <jats:italic>A. americanum<\/jats:italic> was positive for <jats:italic>Borrelia lonestari<\/jats:italic>.
