abstract= A slow-growing non-chromogenic mycobacterium was isolated from a patient with pulmonary disease. Phenotypically, strain 05-1390T was similar to Mycobacterium intracellulare ATCC 13950T. The 16S rRNA gene sequence (1385 bp) of strain 05-1390T showed a high degree of similarity to those of the M. intracellulare complex, namely Mycobacterium marseillense 5351974T (100 %), M. intracellulare ATCC 13950T (99.8 %) and Mycobacterium chimaera DSM 44623T (99.9 %). Phylogenetic analysis based on internal transcribed spacer 1 (ITS1) and the hsp65 gene indicated that strain 05-1390T was closely related to M. intracellulare ATCC 13950T, but that it was a distinct phylogenetic entity. Of particular interest, an analysis based on the rpoB gene (701 bp) showed that it is closely related to Mycobacterium parascrofulaceum ATCC BAA-614T (99.4 %), a scotochromogenic strain, rather than to the M. intracellulare -related strains. Unique MALDI-TOF MS profiles also supported the taxonomic status of this strain as a distinct species. These data support the conclusion that strain 05-1390T represents a novel mycobacterial species, for which the name Mycobacterium yongonense sp. nov. is proposed; the type strain is 05-1390T ( = DSM 45126T = KCTC 19555T).,
