Streptococcus bouchesdurhonensis sp. nov. isolated from a bronchoalveolar lavage of a patient with pneumonia

Strain Marseille-Q6994 was isolated from a 72-year-old patient with pneumonia from Bouches-du-Rhône department, in France. Cells were Gram positive, non-motile, catalase and oxidase-negative cocci. The major fatty acids were hexadecanoic (47.4%) and tetradecanoic acids (28.3%). 16S rRNA gene sequence comparison suggested that strain Marseille-Q6994 was affiliated to the Streptococcus genus. GroEL phylogenetic analysis separated strain Marseille-Q6994 in a distinct branch from the closely related Streptococcus-type strains with standing in nomenclature. Whole genome sequencing-based methods (OrthoAverage Nucleotide Identity, digital DNA-DNA hybridization and pangenome analysis) supported the classification of the strain into a novel species. Therefore, based on the phenotypic, genomic, and phylogenetic analyses, we propose the name Streptococcus bouchesdurhonensis sp. nov for which strain Marseille-Q6994^T (CSUR Marseille-Q6994 = DSMZ 113892) is the type strain.
