sp. nov., a member of the family isolated from a mouse model of spontaneous colitis, and emended description of the genus Clavel 2009 Free

Abstract

The C3H/HeJBir mouse model of intestinal inflammation was used for isolation of a Gram-positive, rod-shaped, non-spore-forming bacterium (B7) from caecal suspensions. On the basis of partial 16S rRNA gene sequence analysis, strain B7 was a member of the class , family , and was related closely to Mt1B8 (97.6 %). The major fatty acid of strain B7 was C (19.1 %) and the respiratory quinones were mono- and dimethylated. Cells were aerotolerant, but grew only under anoxic conditions. Strain B7 did not convert the isoflavone daidzein and was resistant to cefotaxime. The results of DNA–DNA hybridization experiments and additional physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain B7 from the type strain of . Therefore, strain B7 represents a novel species, for which the name sp. nov. is proposed. The type strain is B7 (=DSM 21839 =CCUG 56815).
