Abstract |
An obligate anaerobic, Gram-reaction-negative, non-sporeforming,
non-motile, rod shaped bacterium designated YMC
B3181T was isolated from the blood of a patient with peritonitis.
Strain B3181T grew at 20 to 40°C with optimum growth
at 37°C. 16S rRNA gene sequence similarity showed strain
B3181T belongs to the genus Parabacteroides and is closely
related to Parabacteroides faecis 157T (97.3%), Parabacteroides
gordonii MS-1T (96.6%), and Parabacteroides goldsteinii
DSM 19448T (95.7%). The G + C content of the genomic DNA
was 42.3 mol%. The major cellular fatty acids were anteiso-
C15:0 and iso-C17:0 3-OH, and the predominant respiratory
quinones were MK-9 and MK-10 menaquinones. Genomic
and chemotaxonomic data supported affiliation of B3181T
with the genus Parabacteroides. Strain B3181T 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 B3181T = LMG
30065T = KACC 19034T) is proposed. |
