Parabacteroides pacaensis sp. nov. and Parabacteroides provencensis sp. nov., two new species identified from human gut microbiota

Abstract

Strains Marseille-P4001 and Marseille-P3668 are new species from the order Bacteroidales isolated from healthy French volunteers. They are anaerobic Gram-negative rod-shaped bacteria. They exhibited 92.68% and 96.68% 16S rRNA sequence identities with Parabacteroides gordonii strain MS-1 and Parabacteroides chinchillae JCM 17104, respectively, the phylogenetically closest species. Their respective draft genomes measured 5.23 Mb and 3.73 Mb with 39.2 mol% and 40.8 mol% of G + C content. Using a taxonogenomics method, we propose here a brief description of Parabacteroides pacaensis sp. nov., strain Marseille-P4001T and Parabacteroides provencensis sp. nov., strain Marseille-P3668T as new bacterial species.
