蜱是一种独特的吸血寄生虫，具有重要的医学和兽医意义。蜱也是几种母体遗传的共生细菌的宿主，这些共生细菌是非致病性细菌，在蜱的生物学和共同感染病原体的传播中具有潜在的作用。为了全面了解蜱虫中的这些共生体，我们根据现有数据概述了它们在蜱虫中的发病率和生物学重要性。蜱中的共生体是多种多样的，其发病率和频率在不同蜱种和同一蜱种的不同地理种群中存在差异。在某些情况下，科希氏菌、弗朗西斯氏菌和立克次体属的共生体可能为蜱宿主提供蜱特有食物来源所缺乏的必需营养物质，并与其宿主表现出互惠关系。然而，大多数共生体是兼性的，并通过各种方式影响其蜱宿主的生物学表型。对于某些菌株，先进的基因组数据和系统发育研究揭示了它们与宿主的相互作用以及致病和互惠形式的进化转变。这些发现对于理解蜱-共生关系有价值，并可能有助于制定控制蜱和蜱传疾病的新策略。
Abstract Ticks are exclusive blood-feeding parasites that are of medical and veterinary importance. Ticks are also host for several maternally inherited symbiotic bacteria that are non-pathogenic bacteria and have potential roles in tick biology and the transmission of co-infecting pathogens. In order to gain a comprehensive view of these symbionts in ticks, we overviewed their incidence and biological importance within ticks based on available data. The symbionts in ticks are diverse, and their incidence and frequency vary across different tick species and different geographical populations of the same species. In some cases, symbionts of Coxiella, Francisella and Rickettsia genera may provide tick hosts essential nutrients absent from the exclusive food source of ticks and exhibit mutualistic relationships with their hosts. However, most symbionts are facultative and affect the biological phenotypes of their tick hosts through various ways. For some strains of Coxiella and Francisella, advanced genomic data and phylogenetic investigations have revealed their interactions with hosts and their evolutionary transitions of pathogenic and mutualistic forms. These findings are valuable for understanding tick-symbiont associations, and may help to develop new strategies to control ticks and tick-borne diseases.
