Two bacterial strains isolated from different hospitals in Japan were subjected to a polyphasic analysis. Strains IFM 0803(T) and IFM 10383 were found to have morphological, biochemical, physiological and chemotaxonomic properties consistent with their classification in the genus Nocardia. Strains IFM 0803(T) and IFM 10383 clustered with the type strain of Nocardia xishanensis, showing 16S rRNA gene sequence similarities of 98.6-98.9 % with this species. The novel strains could be distinguished from N. xishanensis by a range of phenotypic properties. Based on their phenotypic and phylogenetic characteristics, the two isolates are proposed as members of a novel species of the genus Nocardia, Nocardia exalbida sp. nov., with the type strain IFM 0803(T) (=NBRC 100660(T) = JCM 12667(T) = DSM 44883(T)).
对从日本不同医院分离出的两株细菌进行了多相分析。发现菌株IFM 0803(T)和IFM 10383具有与诺卡氏菌属分类相一致的形态、生化、生理和化学分类学特性。菌株IFM 0803(T)和IFM 10383与西山诺卡氏菌模式菌株聚类，与该种的16S rRNA基因序列相似性为98.6 - 98.9%。这些新菌株可通过一系列表型特性与西山诺卡氏菌区分开来。基于它们的表型和系统发育特征，这两株分离株被提议为诺卡氏菌属一个新种——白色诺卡氏菌（Nocardia exalbida sp. nov.）的成员，模式菌株为IFM 0803(T)（=NBRC 100660(T) = JCM 12667(T) = DSM 44883(T)）。
