Risungbinella massiliensis sp nov., a new member of Thermoactinomycetaceae isolated from human gut

Résumé

A novel filamentous bacterium, designated GD1(T), was isolated from the gut microbiota of a 38-year-old male who suffered from a Coxiella burnetii vascular for which he received multiple a broad-spectrum antibiotic cocktail at the time of the stool collection. The strain was isolated as a part of culturomics study by cultivation on 5 % sheep blood agar in aerobic condition at 28 A degrees C, after 14 days of incubation. Strain GD1(T) shows 16S rRNA gene sequence similarities of 98.01 % to the type strain of Risungbinella pyongyangensis. We describe here the features of this bacterium, together with the complete genome sequence and annotation. The G+C content of the genomic DNA was determined to be 40.1 mol %. The major fatty acids of strain GD1(T) were identified as iso-C15:0, iso-C17:0, anteiso-C15:0, iso-C14:0 and C16:0. The 3,440,191 bp long genome contains 3540 protein-coding and 67 RNA genes, including three rRNA genes. Strain GD1(T) (= DSM 46691 = CSUR P1082) sp. nov. is here classified as the type strain of a new species, Risungbinella massiliensis, within the family Thermoactinomycetaceae. To date, strain GD1(T) is the first member of the family Thermoactinomycetaceae isolated from human gut and the fourth from a human specimen.
