遗传细菌已被公认为节肢动物生物学的重要组成部分。除了互惠共生外，已知一系列其他遗传细菌作为生殖寄生虫或次级共生体。虽然α-变形杆菌沃尔巴克氏体的发病率相对较好地建立，但目前对其他遗传性细菌的认识要弱得多。在这里，我们测试了136种节肢动物的一系列已知的遗传细菌，证明生殖寄生，采样每个物种比过去的调查更密集。纳入除沃尔巴克氏体以外的遗传细菌使我们样本中记录的感染数量从33增加到57，感染物种的比例从22.8%增加到32.4%。因此，虽然沃尔巴克氏体仍然是占主导地位的遗传细菌，但它单独负责采样细菌的所有遗传感染的一半左右，Cardinium，Arsenophonus和Spiroplasma ixodetis分支的成员分别占所有物种的4%至7%。观察到感染在宿主种群内有时是罕见的，并且种群间共生体的存在差异，这表明我们的调查本身将强调发病率。这项广泛的调查表明，至少有三分之一的节肢动物物种被不同的母体遗传细菌感染，这些细菌可能会强烈影响其宿主的生物学，并表明迫切需要建立非沃尔巴克氏体细菌与其宿主之间相互作用的性质。
Inherited bacteria have come to be recognised as important components of arthropod biology. In addition to mutualistic symbioses, a range of other inherited bacteria are known to act either as reproductive parasites or as secondary symbionts. Whilst the incidence of the α-proteobacterium Wolbachia is relatively well established, the current knowledge of other inherited bacteria is much weaker. Here, we tested 136 arthropod species for a range of inherited bacteria known to demonstrate reproductive parasitism, sampling each species more intensively than in past surveys. The inclusion of inherited bacteria other than Wolbachia increased the number of infections recorded in our sample from 33 to 57, and the proportion of species infected from 22.8% to 32.4%. Thus, whilst Wolbachia remained the dominant inherited bacterium, it alone was responsible for around half of all inherited infections of the bacteria sampled, with members of the Cardinium, Arsenophonus and Spiroplasma ixodetis clades each occurring in 4% to 7% of all species. The observation that infection was sometimes rare within host populations, and that there was variation in presence of symbionts between populations indicates that our survey will itself underscore incidence. This extensive survey demonstrates that at least a third of arthropod species are infected by a diverse assemblage of maternally inherited bacteria that are likely to strongly influence their hosts' biology, and indicates an urgent need to establish the nature of the interaction between non-Wolbachia bacteria and their hosts.
