Abstract:
A pathogenic scotochromogenic Mycobacterium xenopi -like organism was isolated from the lung of an immunocompetent young woman. This pathogen caused severe bilateral cavitary lung disease, making two surgical interventions necessary after years of chronic disease. This case prompted us to characterize this mycobacterium by a polyphasic taxonomic approach. The isolate contained chemotaxonomic markers which were typical for the genus Mycobacterium , i.e., the meso isomer of 2,6-diaminopimelic acid, arabinose, and galactose as diagnostic whole-cell sugars, MK-9(H 2 ) as the principal isoprenoid quinone, a mycolic acid pattern of α-mycolates, ketomycolates, and wax ester mycolates, unbranched saturated and unsaturated fatty acids plus a significant amount of tuberculostearic acid, and small amounts of a C 20:0 secondary alcohol. On the basis of its unique 16S rRNA and 16S-23S spacer gene sequences, we propose that the isolate should be assigned to a new species, Mycobacterium heckeshornense . This novel species is phylogenetically closely related to M. xenopi . The type strain of M. heckeshornense is strain S369 (DSM 44428 T ). The GenBank accession number of the 16S rRNA gene of M. heckeshornense is AF174290 .
