Abstract

A previously undescribed, slowly growing, scotochromogenic mycobacterium was isolated from a patient with symptomatic pulmonary infection during sequence-based identification of Korean clinical isolates. Phenetic characteristics of this strain were generally similar to those of and . However, some phenetic characteristics differentiated it from these two species. Its 16S rRNA gene sequences were unique and phylogenetic analysis based on 16S rRNA gene sequences placed the organism in the slowly growing group close to and . Its unique mycolic acid profiles and the results of phylogenetic analysis based on two independent alternative chronometer molecules, and , confirmed the taxonomic status of this strain as representing a novel species. These data support the conclusion that this strain represents a novel mycobacterial species, for which the name sp. nov. is proposed. The type strain is strain 03-19 (=DSM 44998=KCTC 19146).
