The maternally inherited obligate intracellular bacteria infects the reproductive tissues of a wide range of arthropods and affects host reproduction. is a credible biocontrol agent for reducing the impact of diseases associated with arthropod vectors. is a small staphylinid beetle that causes dermatitis linearis and conjunctivitis in humans when they come into contact with skin. occur in this beetle, but their relatedness to other , their infection dynamics, and their potential host effects remain unknown. In this study, we report the phylogenetic position and density dynamics of in . The phylogeny of based on an analysis of MLST genotyping showed that the bacteria from belong to supergroup B. Quantitative PCR indicated that the infection density in adults was higher than in any other life stage (egg, larva or pupa), and that reproductive tissue in adults had the highest infection densities, with similar densities in the sexes. These findings provide a starting point for understanding the infection dynamics in , and interactions with other components of the microbiota.
这种母系遗传的专性细胞内细菌感染多种节肢动物的生殖组织并影响宿主繁殖。它是一种可靠的生物防治剂，可减少与节肢动物媒介相关疾病的影响。它是一种小型隐翅虫甲虫，人类接触其皮肤时会引发线状皮炎和结膜炎。这种细菌存在于这种甲虫体内，但其与其他细菌的亲缘关系、感染动态及其潜在的宿主效应仍不清楚。在本研究中，我们报告了该细菌在这种甲虫中的系统发育位置和密度动态。基于多位点序列分型（MLST）基因分型分析的该细菌系统发育表明，来自这种甲虫的细菌属于B超群。定量PCR表明，成虫中的感染密度高于任何其他生命阶段（卵、幼虫或蛹），且成虫的生殖组织感染密度最高，两性中的密度相似。这些发现为理解该细菌在这种甲虫中的感染动态以及与微生物群其他成分的相互作用提供了一个起点。
