Taxono-genomics description of 'Lactobacillus raoultii sp. nov.', strain Marseille-P4006(T), a new Lactobacillus species isolated from the female genital tract of a patient with bacterial vaginosis.

Strain Marseille-P4006(T), a Gram-stain-positive, rod-shaped, non-sporulating, facultatively anaerobic bacterium, was isolated from the vaginal swab of a 45-year-old woman with recurrent bacterial vaginosis. We studied its phenotypic characteristics and sequenced its whole genome. The major fatty acids were C(16:0) (48%), C(19:1n9) (14%) and C(18:0) (11%). The 3 070 142-bp-long genome contains 2855 protein-coding genes and 68 RNAs. Strain Marseille-P4006(T) exhibited 98.1% 16S rRNA similarity with Lactobacillus farraginis, the closest species phylogenetically. Thus, strain Marseille-P4006 is distinct enough to represent a new species for which we propose the name Lactobacillus raoultii sp. nov. The type strain is Marseille-P4006(T).
