Description of some coryneform bacteria isolated from human clinical specimens as Corynebacterium falsenii sp. nov.
Over a five-year period, four strains of a yellowish-pigmented coryneform bacterium were received for identification by the Culture Collection of the University of Göteborg. All strains had been isolated from normally sterile human body fluids. Initial biochemical characterization revealed that all four isolates were very similar, with weak pyrazinamidase and urease activities, as well as slow fermentative acid production from glucose as the most significant phenotypic features which differentiated the strains from all other presently defined corynebacteria. Chemotaxonomic investigations demonstrated that the strains belonged to the genus Corynebacterium. SDS-PAGE of whole-cell proteins suggested that all four strains were representatives of the same species. Comparative 16S rRNA gene sequence analysis unambiguously demonstrated that the four strains were genealogically related and represent a new subline within the genus Corynebacterium for which the designation Corynebacterium falsenii sp. nov. is proposed. The type strain of Corynebacterium falsenii is CCUG 33651.
