title: Dermabacter vaginalis sp. nov., isolated from human vaginal fluid.
abstract: A novel actinobacterial strain, AD1-86T, was isolated from the vaginal fluid of a Korean female and was characterized by a polyphasic approach. The strain was a facultatively anaerobic, Gram-stain-positive, non-spore-forming, non-motile, catalase-positive and oxidase-negative short rod. Colonies were creamy white, of low convexity and 1-2 mm in diameter after growth on DSM 92 agar plates at 37 °C for 2 days. The most closely related strains were Dermabacter hominis DSM 7083T and Helcobacillus massiliensis 6401990T (98.3 and 96.3 % 16S rRNA gene sequence similarity, respectively). The isolate grew optimally at 37 °C and pH 7 in the presence of 0.5% (w/v) NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid and the cell-wall hydrolysates contained ribose, galactose and glucose. The DNA G+C content was 62.6 mol% and the mean DNA-DNA relatedness value of the isolate to D. hominis DSM 7083T was 31.1±3.0% (reciprocal: 48.2±5.3%). The major cellular fatty acids (>10%) were anteiso-C17:0, anteiso-C15:0 and iso-C16:0, and the menaquinones were MK-9, MK-8 and MK-7. The polar lipid profile of strain AD1-86T consisted of diphosphatidylglycerol, phosphatidylglycerol, two aminolipids and a glycolipid. Data from this polyphasic study indicate that strain AD1-86T represents a novel species of the genus Dermabacter, for which the name Dermabacter vaginalis sp. nov. is proposed; the type strain is AD1-86T (=KCTC 39585T=DSM 100050T).
