Mycobacterium paraterrae sp. nov. recovered from a clinical specimen: Novel chromogenic slow growing mycobacteria related to Mycobacterium terrae complex

Abstract

Apreviously unidentified, slowly growing scotochromogenicMycobacterium was isolated from aKorean patient with symptomatic pulmonary infection. Phenotypically, this strain was generally similar to Mycobacterium terrae complex strains, however it uniquely produced orange pigmentation. Unique mycolic acid profiles and phylogenetic analyses based on three alternative chronometer molecules, 16S rRNAgene, hsp65 and rpoB, confirmed the taxonomic status of this strain as a novel species. These results support that this strain represents a novelMycobacterium species. The nameMycobacterium paraterrae sp. nov. is proposed. The type strain is 05-2522 (= DSM 45127 = KCTC 19556). © 2009 The Societies and Blackwell Publishing Asia Pty Ltd.
