我们研究了虱子四亚目中的三亚目中的六种。这些虱子感染了来自A和F超群的沃尔巴克氏菌。这是首次报道虱子感染超群F沃尔巴克氏菌。迄今为止，来自超群F的沃尔巴克氏体已经在丝状线虫，曼索菌属中被发现，很少在昆虫中被发现。我们利用小亚基核糖体RNA基因（SSU rRNA）的核苷酸序列，从虱子和所有沃尔巴克氏体超群的代表中推断出沃尔巴克氏体的系统发育。没有证据表明虱子的分类群和感染虱子的沃尔巴克氏菌是一致的。没有证据表明沃尔巴克氏体和它们的宿主虱子至少在沃尔巴克氏体超级群体的水平上共同进化。我们提出了沃尔巴克氏体在不同种类的鸟类虱子之间水平转移的一种新机制：沃尔巴克氏体在海马蝇的遗传过程中转移。
We studied six species of lice from three of the four suborders of lice. These lice were infected with Wolbachia bacteria from supergroups A and F. This is the first report of an infection of supergroup F Wolbachia in lice. To date, Wolbachia from supergroup F have been found in filarial nematodes, Mansonella spp., and, rarely, in insects. We inferred the phylogeny of the Wolbachia from lice and representatives of all Wolbachia supergroups, with nucleotide sequences from the small subunit ribosomal RNA gene (SSU rRNA). There was no evidence of congruence between the taxon of louse and the Wolbachia bacteria that infect lice. There is no evidence that Wolbachia and their louse hosts co-evolved at least at the level of Wolbachia supergroups. We propose a novel mechanism for the horizontal transfer of Wolbachia between different species of lice from birds: transfer of Wolbachia during phoresis by hippoboscid flies.
