在美国，变异德氏菌和安德森德氏德氏菌被认为是立克次体的关键媒介，立克次体是落基山斑点热病的病原体。通过区域监测，发现了种类繁多的立克次体。已被记录在变色丝虫和皮革菌中。已经被认为是包括巴贝斯虫在内的各种其他病原体的潜在媒介。和犬埃里希菌。为了更好地确定粉尘螨病原菌的流行率和多样性。在美国各地，对2018年至2019年从44/50个州的狗和猫身上收集的848只扁虱进行了聚合酶链式反应检测立克次体特有的17 kDa和ompA基因片段；还进行了针对巴贝斯虫18S和大亚基区rRNA基因片段的聚合酶链式反应。犬E.canis的16S rRNA基因。立克次体在12.5%(106/848)的硬蜱中检出。检出的种类包括蒙丹立克次体(n = ticks)、贝氏立克次体(n = 15 ticks)、立克次体(n = 13 ticks)、孔雀立克次体(n = 8 ticks)、弱弱立克次体(n = 3 ticks)、冷凉立克次体(n = 1 ticey)和未分类立克次体(Rickettsia spp.)(n = 2刻度)。来自美国每个地区的人都提交了携带蒙丹立克次体和贝氏立克次体的硬蜱；主要在美国南半部的硬蜱中检测到立克次体，而所有孔雀立克次体阳性的硬蜱都是起源于落基山脉各州的安德森立克次体。2只白纹伊蚊均未检出犬埃立克体，2只白纹伊蚊检出康巴贝斯虫。因为大多数扁虱在提交之前都以狗或猫为食，所以这些发现并不涉及到某个特定的粉虱。作为这些病原体的主要媒介，但关于立克次体，这些数据确实支持其他已发表的工作，表明可变立克次体含有对动物和人类健康未知影响的多样性立克次体物种。
In the United States, Dermacentor variabilis and Dermacentor andersoni are considered key vectors for Rickettsia rickettsii, the causative agent of Rocky Mountain spotted fever. Through regional surveillance, a wide diversity of Rickettsia spp. have been documented in D. variabilis, and Dermacentor spp. has been suggested as potential vectors for various other pathogens, including Babesia spp. and Ehrlichia canis. To better define the prevalence and diversity of pathogens in Dermacentor spp. across the United States, 848 ticks collected from dogs and cats in 44/50 states in 2018–2019 were tested by PCR for Rickettsia spp.-specific 17 kDa and ompA gene fragments; a subset of Dermacentor spp. was also tested with PCR, targeting fragments of the 18S and large subunit region rRNA genes of Babesia spp. and 16S rRNA genes of E. canis. Rickettsia spp. was identified in 12.5% (106/848) of ticks. Species detected include Rickettsia montanensis (n = 64 ticks), Rickettsia bellii (n = 15 ticks), Rickettsia rhipicephali (n = 13 ticks), Rickettsia peacockii (n = 8 ticks), Rickettsia amblyommatis (n = 3 ticks), Rickettsia cooleyi (n = 1 tick), and unclassified Rickettsia spp. (n = 2 ticks). Ticks with R. montanensis and R. bellii were submitted from every U.S. region; R. rhipicephali was predominantly detected in ticks from the southern half of the United States, and all R. peacockii-positive ticks were D. andersoni that originated from the Rocky Mountain states. Ehrlichia canis was not detected in any Dermacentor spp., and Babesia conradae was detected in two Dermacentor albipictus. Because most ticks had fed on dogs or cats before submission, these findings do not implicate a given Dermacentor sp. as a primary vector of these agents, but in regard to Rickettsia spp., the data do support other published work showing D. variabilis harbors a diversity of Rickettsia species with unknown implications for animal and human health.
