Abstract
Three human clinical strains (W9323(T), X0209(T) and X0394) isolated from a lung biopsy, blood and cerebral spinal fluid, respectively, were characterised using a polyphasic taxonomic approach. Comparative analysis of the 16S rRNA gene sequences showed the three strains belong to two novel branches within the genus Kroppenstedtia: 16S rRNA gene sequence analysis of W9323(T) showed close sequence similarity to Kroppenstedtia eburnea JFMB-ATE(T) (95.3 %), Kroppenstedtia guangzhouensis GD02(T) (94.7 %) and strain X0209(T) (94.6 %); sequence analysis of strain X0209(T) showed close sequence similarity to K. eburnea JFMB-ATE(T) (96.4 %) and K. guangzhouensis GD02(T) (96.0 %). Strains X0209(T) and X0394 were 99.9 % similar to each other by 16S rRNA gene sequence analysis. The DNA-DNA relatedness was 94.6 %, confirming that X0209(T) and X0394 belong to the same species. Chemotaxonomic data for strains W9323(T) and X0209(T) were consistent with those described for the members of the genus Kroppenstedtia: the peptidoglycan was found to contain LL-diaminopimelic acid; the major cellular fatty acids were identified as iso-C15 and anteiso-C15; and the major menaquinone was identified as MK-7. Differences in endospore morphology, carbon sou...Continue Reading
