Abstract

A previously unidentified, slowly growing, scotochromogenic species, represented by strain 31118, was discovered during sequence-based reidentification of Korean clinical isolates that had been previously identified as by conventional biochemical tests. Although the 16S rRNA gene sequence of strain 31118 was identical to that of the recently described , phylogenetic analyses based on three independent alternative targets (, and the 16S–23S internal transcribed spacer) showed that it was closely related to but was a distinct phylogenetic entity. Furthermore, the phenetic characteristics of this strain were more similar to those of than to those of . Taken together, these results support the conclusion that this strain represents a novel mycobacterium species, for which the name sp. nov. is proposed. The type strain is 31118 (=DSM 45000 =KCTC 19145).
