Gibbsiella dentisursi sp. nov., isolated from the bear oral cavity

ABSTRACT A Gram‐negative, rod‐shaped, non‐spore forming and non‐motile bacterium, designated strain NUM 1720T, was isolated from the oral cavity of bears. Based on 16S rRNA gene sequence similarity, strain NUM 1720T was shown to be related to Gibbsiella quercinecans (99.4%). The gyrB and rpoB gene s...

Description
Summary:ABSTRACT A Gram‐negative, rod‐shaped, non‐spore forming and non‐motile bacterium, designated strain NUM 1720T, was isolated from the oral cavity of bears. Based on 16S rRNA gene sequence similarity, strain NUM 1720T 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 1720T 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 1720T to the genus Gibbsiella. The major menaquinone and ubiquinone were MK‐8 and Q‐8, respectively. Strain NUM 1720T can be differed from G. quercinecans by the reactions to acetoin, inositol and D‐arabinose. Strain NUM 1720T therefore represents a novel species, for which the name Gibbsiella dentisursi sp. nov. is proposed, with type strain NUM 1720T (= JCM 17201T = DSM 23818T).
