Abstract

Strain SMR-C, which was originally isolated from rats as the SMR strain, had been named ‘cilia-associated respiratory bacillus’ (‘CAR bacillus’). ‘CAR bacillus’ was a Gram-stain-negative, filamentous argentophilic bacterium without flagella. SMR-C 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-C and anteiso-C. The DNA G+C content was 47.7 mol%. 16S rRNA gene sequence analysis revealed SMR-C and other strains of ‘CAR bacillus’ isolated from rodents all belonged to the phylum . The nearest known type strain, with 86 % 16S rRNA gene sequence similarity, was DSM 2588 in the family . Strain SMR-C and closely related strains of ‘CAR bacillus’ rodent-isolates formed a novel family-level clade in the phylum with high bootstrap support (98–100 %). Based on these results, we propose a novel family, fam. nov., in the order as well as a novel genus and species, gen. nov., sp. nov., for strain SMR-C. The type strain is SMR-C ( = JCM 19453 = DSM 100392).
