Characterization of an Isolate Belonging to the Newly Described Species Mycobacterium hassiacum

Abstract

The isolation, from a urine sample, of a rapidly growing acid-fast mycobacterium assigned to the thermophilic species Mycobacterium hassiacum led to further insight into present knowledge of this newly described organism. Already known phenotypic traits of M. hassiacum were extended and its susceptibility to additional antimicrobials was investigated. The high-performance liquid chromatography pattern of mycolic acids is, for the first time, presented. So far, no clinical relevance was proved for our isolate; likewise for the one which led to the species’ original description.
