Mites are often overlooked as vectors of pathogens, but have been shown to harbor and transmit rickettsial agents such as Rickettsia akari and Orientia tsutsugamushi. We screened DNA extracts from 27 mites representing 25 species of dermanyssoids for rickettsial agents such as Anaplasma, Bartonella, Rickettsia, and Wolbachia by PCR amplification and sequencing. DNA from Anaplasma spp., a novel Bartonella sp., Spiroplasma sp., Wolbachia sp., and an unclassified Rickettsiales were detected in mites. These could represent mite-borne bacterial agents, bacterial DNA from blood meals, or novel endosymbionts of mites.
螨类常被忽视作为病原体的传播媒介，但已证明它们能携带并传播立克次氏体病原体，如小蛛立克次氏体和恙虫病东方体。我们通过PCR扩增和测序，对代表25种皮刺螨的27只螨的DNA提取物进行筛选，以检测诸如无形体属、巴尔通体属、立克次氏体属和沃尔巴克氏体属等立克次氏体病原体。在螨类中检测到了无形体属、一种新型巴尔通体属、螺原体属、沃尔巴克氏体属以及一种未分类的立克次体目的DNA。这些可能代表由螨传播的细菌病原体、血餐中的细菌DNA或螨类的新型内共生菌。
