Five clinical isolates, strains IFM 0137, 0372(T), 0496, 0556, and 0952, were provisionally assigned to the genus Nocardia based on morphological criteria. Nearly complete 16S rDNA sequences were determined for these strains. These data showed that they are most similar to that of Nocardia africana, Nocardia cerradoensis and Nocardia veterana. However, DNA-DNA relatedness data showed that the five strains were of a single species and were distinguishable from N. africana, N. cerradoensis and N. veterana. Therefore, these strains represent a new species within the genus Nocardia. The designation of these five strains is Nocardia aobensis sp. nov. The type strain is IFM 0372(T) (=NBRC 100429(T)=JCM 12352(T)=DSM 44805(T)).
根据形态学标准，5株临床分离株，即菌株IFM 0137、0372(T)、0496、0556和0952，被暂时归类为诺卡氏菌属。测定了这些菌株近乎完整的16S rDNA序列。这些数据表明，它们与非洲诺卡氏菌、塞拉多诺卡氏菌和退伍军人诺卡氏菌最为相似。然而，DNA-DNA相关性数据表明，这5株菌株属于单一物种，且与非洲诺卡氏菌、塞拉多诺卡氏菌和退伍军人诺卡氏菌不同。因此，这些菌株代表了诺卡氏菌属内的一个新物种。这5株菌株的名称为青森诺卡氏菌（Nocardia aobensis）新种。模式菌株为IFM 0372(T)（=NBRC 100429(T)=JCM 12352(T)=DSM 44805(T)）。
