A Gram‐negative, rod‐shaped, non‐spore forming and non‐motile bacterium, designated strain NUM 1720 T , was isolated from the oral cavity of bears. Based on 16S rRNA gene sequence similarity, strain NUM 1720 T was shown to be related to Gibbsiella quercinecans (99.4%). The gyrB and rpoB gene sequences of strain NUM 1720T showed 98.0% and 98.2% similarity with those of G. quercinecans . The DNA‐DNA hybridization value of strain NUM 1720 T with G. quercinecans was 63.8%. The G + C content of the genomic DNA of the isolates was 55.0 mol%. Fatty acid analysis data supported the affiliation of strain NUM 1720 T to the genus Gibbsiella . The major menaquinone and ubiquinone were MK‐8 and Q‐8, respectively. Strain NUM 1720 T can be differed from G. quercinecans by the reactions to acetoin, inositol and D‐arabinose. Strain NUM 1720 T therefore represents a novel species, for which the name Gibbsiella dentisursi sp. nov. is proposed, with type strain NUM 1720 T (= JCM 17201 T = DSM 23818 T ).
