Molecular Taxonomic Evidence for Two Distinct Genotypes of Mycobacterium yongonense via Genome-Based Phylogenetic Analysis.

Project description:Recently, we introduced a distinct Mycobacterium intracellulare INT-5 genotype, distantly related to other genotypes of M. intracellulare (INT-1 to -4). The aim of this study is to determine the exact taxonomic status of the M. intracellulare INT-5 genotype via genome-based phylogenetic analysis. To this end, genome sequences of the two INT-5 strains, MOTT-H4Y and MOTT-36Y were compared with M. intracellulare ATCC 13950(T) and Mycobacterium yongonense DSM 45126(T). Our phylogenetic analysis based on complete genome sequences, multi-locus sequence typing (MLST) of 35 target genes, and single nucleotide polymorphism (SNP) analysis indicated that the two INT-5 strains were more closely related to M. yongonense DSM 45126(T) than the M. intracellulare strains. These results suggest their taxonomic transfer from M. intracellulare into M. yongonense. Finally, we selected 5 target genes (argH, dnaA, deaD, hsp65, and recF) and used SNPs for the identification of M. yongonese strains from other M. avium complex (MAC) strains. The application of the SNP analysis to 14 MAC clinical isolates enabled the selective identification of 4 M. yongonense clinical isolates from the other MACs. In conclusion, our genome-based phylogenetic analysis showed that the taxonomic status of two INT-5 strains, MOTT-H4Y and MOTT-36Y should be revised into M. yongonense. Our results also suggest that M. yongonense could be divided into 2 distinct genotypes (the Type I genotype with the M. parascrofulaceum rpoB gene and the Type II genotype with the M. intracellulare rpoB gene) depending on the presence of the lateral gene transfer of rpoB from M. parascrofulaceum.

The development of a novel Mycobacterium-Escherichia coli shuttle vector system using pMyong2, a linear plasmid from Mycobacterium yongonense DSM 45126T.

Project description:The Mycobacterium-Escherichia coli shuttle vector system, equipped with the pAL5000 replicon, is widely used for heterologous gene expression and gene delivery in mycobacteria. Despite its extensive use, this system has certain limitations, which has led to the development of alternative mycobacterial vector systems. The present study describes the molecular structure and expression profiles of a novel 18-kb linear plasmid, pMyong2, from Mycobacterium yongonense. Sixteen open reading frames and a putative origin of replication were identified, and the compatibility of the pMyong2 and pAL5000 vector systems was demonstrated. In recombinant Mycobacterium smegmatis (rSmeg), the pMyong2 vector system showed a copy number that was approximately 37 times greater than that of pAL5000. Furthermore, pMyong2 increased the mRNA and protein expression of the human macrophage migration inhibitory factor (hMIF) over pAL5000 levels by approximately 10-fold and 50-fold, respectively, demonstrating the potential utility of the pMyong2 vector system in heterologous gene expression in mycobacteria. Successful delivery of the EGFP gene into mammalian cells via rSmeg carrying the pMyong2 vector system was also observed, demonstrating the feasibility of this system for DNA delivery. In conclusion, the pMyong2 vector system could be effectively used not only for the in vivo delivery of recombinant protein and DNA but also for mycobacterial genetic studies as an alternative or a complement to the pAL5000 vector system.

Molecular evidence of lateral gene transfer in rpoB gene of Mycobacterium yongonense strains via multilocus sequence analysis.

Project description:Recently, a novel species, Mycobacterium yongonense (DSM 45126(T)), was introduced and while it is phylogenetically related to Mycobacterium intracellulare, it has a distinct RNA polymerase ?-subunit gene (rpoB) sequence that is identical to that of Mycobacterium parascrofulaceum, which is a distantly related scotochromogen, which suggests the acquisition of the rpoB gene via a potential lateral gene transfer (LGT) event. The aims of this study are to prove the presence of the LGT event in the rpoB gene of the M. yongonense strains via multilocus sequence analysis (MLSA). In order to determine the potential of an LGT event in the rpoB gene of the M. yongonense, the MLSA based on full rpoB sequences (3447 or 3450 bp) and on partial sequences of five other targets [16S rRNA (1383 or 1395 bp), hsp65 (603 bp), dnaJ (192 bp), recA (1053 bp), and sodA (501 bp)] were conducted. Incongruences between the phylogenetic analysis of the full rpoB and the five other genes in a total of three M. yongonense strains [two clinical strains (MOTT-12 and MOTT-27) and one type strain (DSM 45126(T))] were observed, suggesting that rpoB gene of three M. yongonense strains may have been acquired very recently via an LGT event from M. parascrofulaceum, which is a distantly related scotochromogen.

Pulmonary disease due to Mycobacterium arosiense, an easily misidentified pathogenic novel mycobacterium.

Project description:Mycobacterium arosiense is a newly described species. After noticing it was misidentified as Mycobacterium intracellulare by the commercial identification system GenoType CM (Hein, Nehren, Germany), we detected 4 such strains among 33 that were previously misidentified as M. intracellulare. Three more strains were found among unidentified mycobacteria not tested previously with GenoType. The first case of pulmonary disease due to M. arosiense is reported here, and the novel species, of which so far only one strain had been investigated, is further characterized.

Nontuberculous Mycobacterial Pulmonary Disease from Mycobacterium hassiacum, Austria.

Project description:The clinical relevance of newly described nontuberculous mycobacteria is often unclear. We report a case of pulmonary infection caused by Mycobacterium hassiacum in an immunocompetent patient in Austria who had chronic obstructive pulmonary disease. Antimicrobial drug susceptibility testing showed low MICs for macrolides, aminoglycosides, fluoroquinolones, tetracyclines, imipenem, and linezolid.
