沃尔巴克氏菌是节肢动物中广泛存在的可遗传内共生体，因其对宿主适合性的深刻影响以及对病毒和真核寄生虫的保护而臭名昭著，表明它们可以与共享相同宿主环境的其他微生物相互作用。以陆生等足类甲壳动物Armadillidium uggare、其高度多样性的微生物群(>；200个细菌属)和三个雌性化沃尔巴克氏菌株(wVulC、wVulM、wVulP)为模型系统，本研究表明沃尔巴克氏菌在实验室和自然条件下甚至可以影响多样化细菌群落的组成。虽然寄主来源是普通曲霉微生物区系分类组成的主要决定因素，但沃尔巴克氏菌感染既影响了每个寄主种群中许多细菌分类群的存在，更重要的是影响了其丰度，可能是由于竞争相互作用。此外，不同的沃尔巴克氏菌株对微生物区系组成的影响也不同。因此，感染wVulC比感染wVulM影响的分类群数量更多，这可能是由于这两个菌株在毒力和效价方面的内在差异。总之，这项研究表明，可遗传的内共生体，如沃尔巴克氏菌，可以作为生物因子塑造节肢动物的微生物区系，对宿主适合度的影响尚不清楚。
Wolbachia are widespread heritable endosymbionts of arthropods notorious for their profound effects on host fitness as well as for providing protection against viruses and eukaryotic parasites, indicating that they can interact with other microorganisms sharing the same host environment. Using the terrestrial isopod crustacean Armadillidium vulgare, its highly diverse microbiota (>200 bacterial genera) and its three feminizing Wolbachia strains (wVulC, wVulM, wVulP) as a model system, the present study demonstrates that Wolbachia can even influence the composition of a diverse bacterial community under both laboratory and natural conditions. While host origin is the major determinant of the taxonomic composition of the microbiota in A. vulgare, Wolbachia infection affected both the presence and, more importantly, the abundance of many bacterial taxa within each host population, possibly due to competitive interactions. Moreover, different Wolbachia strains had different impacts on microbiota composition. As such, infection with wVulC affected a higher number of taxa than infection with wVulM, possibly due to intrinsic differences in virulence and titer between these two strains. In conclusion, this study shows that heritable endosymbionts such as Wolbachia can act as biotic factors shaping the microbiota of arthropods, with as yet unknown consequences on host fitness.
