“…An additional eight new species have been validly published since 2006: Mycobacterium arupense (28), Mycobacterium kumamotonense (36), Mycobacterium heraklionense (1), Mycobacterium senuense (40), Mycobacterium minnesotense (41), My-cobacterium longobardum (1), Mycobacterium algericum (42), and Mycobacterium engbaekii (1). Two other MTC species have been described that currently have no standing in nomenclature: "Mycobacterium paraterrae" (43) and "Mycobacterium sinense" (44).…”

Mycobacterium terrae complex (MTC) was first characterized in 1981 by the International Working Group in Mycobacterial Taxonomy (IWGMT). The initial MTC consisted of two nonchromogenic slowly growing species: M. terrae and Mycobacterium nonchromogenicum (1, 2). Phenotypic separation within the group was often difficult, and molecular methods were not available, making establishment of species pathogenicity uncertain (3).The complex is recognized as an environmental contaminant of sputum and a cause of tenosynovitis and osteomyelitis primarily of the fingers and wrist (3-35). Whether one or more members of the complex are true respiratory pathogens has not been established (1, 22).The first published case report of tenosynovitis caused by the MTC was by Hirata and Tomiyama in 1976 (4). There have been approximately 34 additional case reports published since then, identified using nonmolecular methods (3-25), with 14 cases identified using molecular methods (26)(27)(28)(30)(31)(32)(33)(34)(35)(36) (Tables 1 and 2). With the exception of four isolates of M. arupense, including the original description of M. arupense (28), details of the methods and/or explicitly stating a 100% 16S rRNA gene sequence identity to recognized species for the remaining cases with molecular identifications have been absent (Table 2).An excellent history and species update of the M. terrae complex based on multigene sequencing targets was published by Tortoli et al. (1). He noted that the presence of a two nucleotide insertion in helix 18 of the 16S rRNA gene (bp ϳ430 to 500; hypervariable region B or region V3) provided a consistent signature sequence for members of the MTC compared to other slowly growing mycobacteria (37,38). He also characterized several new species in the complex, including Mycobacterium heraklionense and Mycobacterium engbaekii (1).The greater availability of DNA sequencing (59) Citation Vasireddy R, Vasireddy S, Brown-Elliott BA, Wengenack NL, Eke UA, Benwill JL, Turenne C, Wallace RJ, Jr. 2016.

Genome-Based Taxonomic Classification of the Phylum Actinobacteria

et al. 2018

The application of phylogenetic taxonomic procedures led to improvements in the classification of bacteria assigned to the phylum Actinobacteria but even so there remains a need to further clarify relationships within a taxon that encompasses organisms of agricultural, biotechnological, clinical, and ecological importance. Classification of the morphologically diverse bacteria belonging to this large phylum based on a limited number of features has proved to be difficult, not least when taxonomic decisions rested heavily on interpretation of poorly resolved 16S rRNA gene trees. Here, draft genome sequences of a large collection of actinobacterial type strains were used to infer phylogenetic trees from genome-scale data using principles drawn from phylogenetic systematics. The majority of taxa were found to be monophyletic but several orders, families, and genera, as well as many species and a few subspecies were shown to be in need of revision leading to proposals for the recognition of 2 orders, 10 families, and 17 genera, as well as the transfer of over 100 species to other genera. In addition, emended descriptions are given for many species mainly involving the addition of data on genome size and DNA G+C content, the former can be considered to be a valuable taxonomic marker in actinobacterial systematics. Many of the incongruities detected when the results of the present study were compared with existing classifications had been recognized from 16S rRNA gene trees though whole-genome phylogenies proved to be much better resolved. The few significant incongruities found between 16S/23S rRNA and whole genome trees underline the pitfalls inherent in phylogenies based upon single gene sequences. Similarly good congruence was found between the discontinuous distribution of phenotypic properties and taxa delineated in the phylogenetic trees though diverse non-monophyletic taxa appeared to be based on the use of plesiomorphic character states as diagnostic features.

A 59-year-old tobacco smoker male with chronic bronchitis living in Taravao, French Polynesia, Pacific, presented with a two-year growing nodule in the middle lobe of the right lung. A guided bronchoalveolar lavage inoculated onto Löwenstein-Jensen medium yielded colonies of a rapidly-growing non-chromogenic mycobacterium designed as isolate P7213. The isolate could not be identified using routine matrix-assisted laser desorption ionization-time of flight-mass spectrometry and phenotypic and probe-hybridization techniques and yielded 100% and 97% sequence similarity with the respective 16S rRNA and rpoB gene sequences of Mycobacterium virginiense in the Mycobacterium terrae complex. Electron microscopy showed a 1.15 µm long and 0.38 µm large bacillus which was in vitro susceptible to rifampicin, rifabutin, ethambutol, isoniazid, doxycycline and kanamycin. Its 4,511,948-bp draft genome exhibited a 67.6% G + C content with 4,153 coding-protein genes and 87 predicted RNA genes. Genome sequence-derived DNA-DNA hybridization, OrthoANI and pangenome analysis confirmed isolate P7213 was representative of a new species in the M . terrae complex. We named this species “ Mycobacterium mephinesia ”.
