Nocardia vermiculata sp. nov. and Nocardia thailandica sp. nov. Isolated from Clinical Specimens

Abstract

The taxonomic positions of actinomycetes isolated from clinical specimens in Japan and Thailand were examined using a polyphasic approach. The strains IFM 0391^T and IFM 10145^T were found to have morphological, biochemical and chemotaxonomic properties consistent with their classification in the genus Nocardia. DNA-DNA hybridization, coupled with sequence analysis of 16S rDNA, indicated that these strains belong to two new species of the genus Nocardia: Nocardia vermiculata for IFM 0391^T (=NBRC 1000427^T = JCM 12345^T = DSM 44807^T), and Nocardia thailandica for IFM 10145^T (=NBRC 100428^T = JCM 12356^T = DSM 44808^T).
