落基山斑疹热、莱姆病和埃立克体病是每年在肯塔基州报告的蜱传疾病。我们进行了一项调查，以描述在肯塔基州收集的美洲钝眼蜱和变异革蜱中蜱传病原体的感染流行率。在2007-2008年期间，我们收集了287只蜱（179只D。variabilis和108 A. americanum）从肯塔基州的六个县的犬、野猪、马、浣熊、白尾鹿和人类宿主中分离。对蜱进行立克次体属筛选，疏螺旋体属，和埃里希体属（Ehrlichia spp.）通过聚合酶链反应。41只蜱（31 A. americanum和10个D. variabilis）为立克次体属（Rickettsia spp.）蜱类6只，占4.9%; americanum和8个D. variabilis）为阳性。chaffeensis和4 A. americanum阳性率为1.4%。埃温吉。A. americanum对疏螺旋体呈阳性。虽然落基山斑疹热在肯塔基州被诊断出来，但没有R。在这项研究中，在蜱中发现了立克次体。
Rocky Mountain spotted fever, Lyme disease, and ehrlichiosis are tick-borne diseases that are reported annually in Kentucky. We conducted a survey to describe infection prevalence of tick-borne pathogens in Amblyomma americanum and Dermacentor variabilis ticks collected in Kentucky. During 2007-2008, we collected 287 ticks (179 D. variabilis and 108 A. americanum) from canine, feral hog, horse, raccoon, white-tailed deer, and human hosts in six counties in Kentucky. Ticks were screened for Rickettsia spp., Borrelia spp., and Ehrlichia spp. by using polymerase chain reaction. Forty-one (14.3%) ticks (31 A. americanum and 10 D. variabilis) were polymerase chain reaction positive for a Rickettsia spp. Fourteen (4.9%) ticks (6 A. americanum and 8 D. variabilis) were positive for E. chaffeensis, and 4 A. americanum (1.4%) were positive for E. ewingii. One (0.4%) A. americanum was positive for Borrelia lonestari. Although Rocky Mountain spotted fever is diagnosed in Kentucky, no R. rickettsii was found in ticks in this study.
