An obligate anaerobic, Gram-reaction-negative, non-sporeforming, non-motile, rod shaped bacterium designated YMC B3181(T) was isolated from the blood of a patient with peritonitis. Strain B3181(T) grew at 20 to 40 degrees C with optimum growth at 37 degrees C. 16S rRNA gene sequence similarity showed strain B3181(T) belongs to the genus Parabacteroides and is closely related to Parabacteroides faecis 157(T) (97.3%), Parabacteroides gordonii MS-1(T) (96.6%), and Parabacteroides goldsteinii DSM 19448(T) (95.7%). The G + C content of the genomic DNA was 42.3 mol%. The major cellular fatty acids were anteiso-C-15:0 and iso-C-17:0 3-OH, and the predominant respiratory quinones were MK-9 and MK-10 menaquinones. Genomic and chemotaxonomic data supported affiliation of B3181(T) with the genus Parabacteroides. Strain B3181(T) was phylogenetically and phenotypically different from recognized species of the genus Parabacteroides. Accordingly, this isolate belongs to a novel species for which the name Parabacteroides chongii sp. nov. (type strain YMC B3181(T) = LMG 30065(T) = KACC 19034(T)) is proposed.
