'CAR bacillus' was a Gram-stain-negative, filamentous argentophilic bacterium without flagella. SMR-CT grew at 37 °C under microaerobic conditions, showed gliding activity, hydrolysed urea and induced chronic respiratory diseases in rodents. The dominant cellular fatty acids detected were iso-C15 : 0 and anteiso-C15 : 0. The DNA G+C content was 47.7 mol%. 16S rRNA gene sequence analysis revealed SMR-CT and other strains of 'CAR bacillus' isolated from rodents all belonged to the phylum Bacteroidetes. The nearest known type strain, with 86 % 16S rRNA gene sequence similarity, was Chitinophaga pinensis DSM 2588T in the family Chitinophagaceae. Strain SMR-CT and closely related strains of 'CAR bacillus' rodent-isolates formed a novel family-level clade in the phylum Bacteroidetes with high bootstrap support (98-100 %). Based on these results, we propose a novel family, Filobacteriaceae fam. nov., in the order Sphingobacteriales as well as a novel genus and species, Filobacterium rodentium gen. nov., sp. nov., for strain SMR-CT. The type strain is SMR-CT ( = JCM 19453T = DSM 100392T).}, pages = {150--157}, title = {Filobacterium rodentium gen. nov., sp. nov., a member of Filobacteriaceae fam. nov. within the phylum Bacteroides, and includes microaerobic fiamentous bacterium isolated from rodent respiratory disease specimens.}, volume = {66}, year = {2016} }
