Enterorhabdus caecimuris sp. nov., a member of the family Coriobacteriaceae isolated from a mouse model of spontaneous colitis, and emended description of the genus Enterorhabdus Clavel et al. 2009.

ABSTRACT: The C3H/HeJBir mouse model of intestinal inflammation was used for isolation of a Gram-positive, rod-shaped, non-spore-forming bacterium (B7(T)) from caecal suspensions. On the basis of partial 16S rRNA gene sequence analysis, strain B7(T) was a member of the class Actinobacteria, family Coriobacteriaceae, and was related closely to Enterorhabdus mucosicola Mt1B8(T) (97.6 %). The major fatty acid of strain B7(T) was C(16 : 0) (19.1 %) and the respiratory quinones were mono- and dimethylated. Cells were aerotolerant, but grew only under anoxic conditions. Strain B7(T) 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
