Abstract

Gram-negative bacteria of the genus exhibit a mutualistic association with steinernematid entomopathogenic nematodes and a pathogenic relationship with insects. Here we describe two isolates of the entomopathogenic nematode collected from China and Japan. 16S rRNA gene sequence similarity and phylogenetic analysis indicated that the isolates obtained from belonged to the genus . Multilocus sequence analysis based on five universal protein-coding gene sequences revealed that the isolates were closely related to DSM 16337 and ID10 but that they exhibited <97 % sequence similarity with these reference strains, which indicated that the isolates were distinct from previously described species. Based on these genetic differences and several differential phenotypic traits, we propose that the isolates represent a novel species of the genus , for which we propose the name sp. nov. The type strain is GDh7 ( = DSM 22670 = CGMCC 1.9166).
