Olsenella uli DSM 7084

Olsenella species, particularly O.uli, are common members of the microbiota associated with primary endodontic infection, sometimes from blood of humans with local oral or gastrointestinal infections, and are also found in the bovine rumen. O.uli has been found to predominate over other Gram-positive rods in root canal samples taken after chemomechanical preparation and intracanal medication, suggesting that this species can resist intracanal disinfection measures and thus may be involved in persistent dental infections.Strain VPI D76D-27CT was isolated from either human gingival crevices or periodontal pockets. The bacteria are nonmotile, Gram-positive rods that occur singly, in pairs, and in short chains; the central part of the cell may swell particularly when grown on solid medium. This strain is microaerotolerant to anaerobic and grows optimally at 37 degrees Celsius. It does not grow on 6.5% w/v NaCl, and is able to ferment glucose, glycogen, trehalose and starch. Lactic acid is a major product of the strain VPI D76D-27CT, which is suspected to be important in inflammatory processes of endodontic infections (adapted from http://standardsingenomics.org/index.php/sigen/article/view/sigs.1082860/sigs.1082860_pdf and PMID 20435744).
