Description of Janibacter massiliensis sp. nov., cultured from the vaginal discharge of a patient with bacterial vaginosis

Abstract

Strain Marseille-P4121^T was isolated from a vaginal sample of a 45-year-old French woman with bacterial vaginosis. It is a Gram-positive, asporogenous, non-motile and aerobic bacterium. Strain Marseille-P4121^T exhibits 98.2% 16S rRNA sequence similarity with Janibacter alkaliphilus strain SCSIO 10480^T, a phylogenetically closely related species with standing in nomenclature. Its major fatty acids were identified as C_18:1ω9 (34.4%), C_16:0 (30.1%), and C_18:0 (19%). The draft genome size of strain Marseille-P4121^T is 2,452,608 bp long with a 72.5% G+C content and contains 2351 protein-coding genes and 49 RNA genes including 3 rRNA genes. We propose that strain Marseille-P4121^T (= CECT 9671^T = CSUR P4121^T) is the type strain of the new species Janibacter massiliensis sp. nov.
