An isolate that was received during a mycobacterial quality control test and which was thought to be a Mycobacterium species was subjected to a polyphasic taxonomic study after mycolic acid analysis showed that it possessed mycolates characteristic of the nocardiae. Further chemotaxonomic and 16S rRNA gene sequence analyses of this isolate demonstrated that it belongs to the genus Nocardia. 16S rRNA gene sequence data, DNA-DNA hybridization studies and the biochemical characteristics of the isolate indicate that it belongs to a novel species that differs from previously described members of the genus Nocardia. The name Nocardia ignorata sp. nov. is proposed for this isolate with the type strain IMMIB R-1434T (= DSM 44496T = NRRL B-24141T).
