Abstract

Nine -like strains were isolated from human gingival crevices and characterized. These strains were gram-negative, straight rods that were motile by means of multiple unipolar flagella. They were asaccharolytic and preferred an anaerobic atmosphere rather than a microaerophilic atmosphere for growth, and their growth was stimulated by formate and fumarate. These strains were biochemically similar to and , but were clearly distinguishable from these organisms by the number of flagella (two to five flagella at one end of the cell), by being catalase positive, by their whole-cell protein profiles, by their Western blot (immunoblot) patterns, and on the basis of DNA-DNA homology data. They could also be differentiated from the other species of the genus The nine -like strains were compared with two strains (FDC 286 and VPI 10279) representing a previously described but unnamed sp. The nine isolates and strains FDC 286 and VPI 10279 were found to be members of a single species. The 16S rRNA sequences of two strains of the newly identified species were compared with the rRNA sequences of 21 reference , and species in order to generate a phylogenetic tree. We propose the name for the newly identified strains; strain SU A4 (= ATCC 51146) is the type strain of this new species.
