title: Nocardia concava sp. nov., isolated from Japanese patients.
abstract: Two actinomycete strains, IFM 0354(T) and IFM 0576, isolated from Japanese patients, were found to have morphological, biochemical and chemotaxonomic properties consistent with their classification in the genus Nocardia. The strains resembled Nocardia otitidiscaviarum and Nocardia uniformis in their phenotypic properties. Comparative 16S rRNA gene sequence analysis showed that the strains are closely related to Nocardia seriolae. DNA-DNA relatedness values and phenotypic differences from N. seriolae indicated that the strains belong to a novel species of Nocardia, for which the name Nocardia concava sp. nov. is proposed. The type strain is IFM 0354(T) (=NBRC 100430(T)=JCM 12351(T)=DSM 44804(T)).
