本文报道了从日本静冈县田间土壤中分离到的日本斯氏线虫（Steinernema kushidai）的一个共生菌新种-日本小杆线虫（Xellabdus japonicus），该菌与其它小杆线虫属（Xellabdusspp.）该种的模式菌株SK-1是一种革兰氏阴性兼性厌氧菌和围毛鞭毛杆菌，具有初级和次级形式的菌落。从精氨酸脱氢酶、苯丙氨酸脱氨酶和赖氨酸脱羧酶的形成、肌苷和L-脯氨酸的同化作用以及肌醇产酸等特征上可以将该菌株与模式菌株嗜黄杆菌区分开来。主要的细胞脂肪酸是16：0、环17：0和18：1。泛醌系统是Q-8。DNA的G+C含量为45.9mol%。SK-1株与其它XEhabdusspp的模式株的DNA有20 ~ 58%的同源性。
A new species,Xenorhabdus japonicus, is proposed as the bacterial symbiont ofSteinernema kushidaiisolated from field soil in Shizuoka Prefecture, Japan.Xenorhabdus japonicuscould be distinguished phenotypically and genetically from otherXenorhabdusspp. The type strain of the species, SK-1, a Gram-negative, facultative anaerobe and peritrichously flagellated rod, has colonies with primary and secondary forms. The strain can be differentiated from the type strain ofXenorhabdus nematophilusby several characters, including the formation of arginine dehydrolase, phenylalanine deaminase and lysine decarboxylase, the assimilation of inosine andL-proline and acid production from inositol. The major cellular fatty acids are 16:0, cyclo 17:0 and 18:1. The ubiquinone system is Q-8. The G+C content of DNA is 45.9 mol%. The DNA of strain SK-1 has 20 to 58% homology with that of the type strains of otherXenorhabdusspp.
