Abstract

A lipophilic coryneform bacterium isolated from a blood culture from a patient with signs of septicaemia was characterized by means of phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of cell-wall chemotype IV and short-chain mycolic acids, which are consistent with the genus . The isolate was characterized biochemically by the very rapid (approx. 60 s) positive result that was obtained in a urease test in the API Coryne system. Comparative 16S rRNA gene sequencing demonstrated that the isolate belonged phylogenetically to the genus . The values for sequence divergence (⩾1.4 %) with respect to known species, together with phenotypic differences, show that the unidentified bacterium represents a novel member of this genus. On the basis of both the phenotypic and phylogenetic data, this isolate should be classified within a novel species of the genus , for which the name sp. nov. is proposed. The type strain is IMMIB RIV-2301 (=DSM 45051=CCUG 53377).
