A novel red-pigmented, Gram-negative, motile, fluorescent, rod-shaped strain, DZ0503SBS1T, with a single lateral flagellum, was isolated from the intestine of nematode Heterorhabditidoides chongmingensis. Comparative 16S rRNA gene sequence analysis indicated that strain is member genus Serratia, sharing highest similarities Serratia marcescens subsp. sakuensis JCM 11315T (99.8 %), S. DSM 30121T (99.5 %) and ureilytica LMG 22860T (98.3 %). Similarities between rpoB DZ0503SBS1T those 11315T, were 98.0, 97.4 98.3 %, respectively. DNA–DNA hybridization values 68.2, 65.1 53.0 The major isoprenoid quinone Q-8 predominant fatty acids C16 : 0 (34.76 cyclo-C17 (20.03 cyclo-C19 ω8c (17.24 content significantly different found in 30121T. Some characteristics i.e. fluorescence its symbiotic association nematodes, have not been reported previously any species Serratia. Phenotypic biochemical molecular data show represents species, for which name nematodiphila sp. nov. proposed; type (=KCTC 22130T =CGMCC 1.6853T).
