Abstract
Parabacteroides massiliensis sp. nov., strain Marseille-P2231(T) (= CSURP2231 = DSM 101860) is a new species within the family Tannerellaceae. It was isolated from a stool specimen of a 25-year-old healthy woman. Its genome was 5 013 798 bp long with a 45.7 mol% G+C content. The closest species based on 16S rRNA sequence was Parabacteroides merdae strain JCM 9497(T) with 98.19% sequence similarity. Considering phenotypic features and comparative genome studies, we proposed the strain Marseille-P2231(T) as the type strain of Parabacteroides massiliensis sp. nov., a new species within the genus Parabacteroides.
