Mycobacterium servetii sp. nov., a novel rapid-growing nontuberculous mycobacterial species recovered from a human patient in Zaragoza, Spain.

In this study, we describe a novel rapid-growing Mycobacterium species isolated from a clinical specimen obtained from the lower respiratory tract of a patient with ciliary dysfunction, bronchiectasis and exacerbated respiratory symptoms. A comprehensive phenotypic characterization was conducted, including the establishment of a MALDI-TOF MS profile. Additionally, whole-genome sequencing was performed to assess overall genomic relatedness indices and conduct phylogenetic comparative analyses. These findings allowed us to characterize a previously unrecognized rapid-growing Mycobacterium species, for which we propose the name Mycobacterium servetii (=DSM 118141; =CECT 31091).
