Phylogenetic relationships of Xenorhabdus spp. and Photorhabdus sp. were investigated on the basis of 16S rRNA gene sequences. Xenorhabdus spp. and Photorhabdus sp. were grouped together with Proteus vulgaris and Arsenophonus nasoniae. This group was distant from other members of the family Enterobacteriaceae. Xenorhabdus japonicus, previously proposed as a new species, was nearly located to Xenorhabdus nematophilus. Signature nucleotides of X. japonicus were identified that distinguish it other members of the family Enterobacteriaceae.
基于16S rRNA基因序列对嗜线虫致病杆菌属（Xenorhabdus spp.）和发光杆菌属（Photorhabdus sp.）的系统发育关系进行了研究。嗜线虫致病杆菌属和发光杆菌属与普通变形杆菌（Proteus vulgaris）及纳氏嗜菌共生体（Arsenophonus nasoniae）归为一组。该组与肠杆菌科的其他成员距离较远。先前被提议作为新物种的日本嗜线虫致病杆菌（Xenorhabdus japonicus）与嗜线虫致病杆菌（Xenorhabdus nematophilus）位置相近。确定了日本嗜线虫致病杆菌的特征性核苷酸，这些核苷酸使其与肠杆菌科的其他成员区分开来。
