Five aerobic actinomycete strains isolated from patients in Japan were assigned provisionally to the genus Nocardia based on morphological and physiological characteristics. The five strains, IFM 10481, IFM 0668, IFM 0901, IFM 0583 and IFM 0342, were not classified into any Nocardia species reported as infectious agents in Japan. Therefore, they were studied further to determine their specific taxonomic positions. Detailed chemotaxonomic and physiologic characterization and 16S rDNA sequence data of the five strains showed that they belonged to respective species of Nocardia carnea, N. elegans, N. paucivorans, N. puris and N. takedensis. This is the first isolation report of these five Nocardia species from patients in Japan.
从日本患者体内分离出的五株需氧放线菌菌株，根据其形态和生理特征被暂时归入诺卡氏菌属。这五株菌株，IFM 10481、IFM 0668、IFM 0901、IFM 0583和IFM 0342，未被归类到日本报道的任何作为感染源的诺卡氏菌物种中。因此，对它们进行了进一步研究以确定其具体的分类地位。这五株菌株的详细化学分类学和生理学特征以及16S rDNA序列数据表明，它们分别属于肉色诺卡氏菌、优美诺卡氏菌、少食诺卡氏菌、紫癜诺卡氏菌和武田诺卡氏菌的各个物种。这是这五种诺卡氏菌物种首次从日本患者体内分离出来的报告。
