Outline of Final Research Achievements

The cilia-associated respiratory bacillus (CARB), formerly unclassified, extracellular, gram-negative filamentous bacterium, colonizes the ciliated respiratory epithelium of rodents and causes persistent respiratory diseases. Previously we improved culture method of CARB of SMR-C strain, extracted genomic DNA from SMR-C and decided its full genome sequences with help of Prof. Hattori and Dr. Oshima at Tokyo University. Genomic analysis showed 40% of annotated genes were not found on the DDBJ/EMBL/Genbank database and we could not speculate virulent factor genes of CARB from its genome.
In this study, we tried to clarify anchoring system of CARB onto epithelial cells, especially focusing on gliding-related genes. Meanwhile we gave scientific name, Filobacterium rodentium, to SMR-C strain also with new genus and family names. We also found F. rodentium displayed stress-induced phase variations including biofilm formation. These findings will help to promote the study of F. rodentium.
