Microbiological Features and Clinical Relevance of New Species of the Genus Mycobacterium

2014

SUMMARY Nontuberculous mycobacteria (NTM) are present in the environment, mainly in water, and are occasionally responsible for opportunistic infections in humans. Despite the fact that NTM are characterized by a moderate pathogenicity, the diseases caused by NTM at various body sites are increasing on a worldwide level. Among over 150 officially recognized NTM species, only two or three dozen are familiar to clinicians, and even to most microbiologists. In this paper, approximately 50 new species described in the last 8 years are reviewed, and their role in human infections is assessed on the basis of reported clinical cases. The small number of reports concerning most of the “new” mycobacterial species is responsible for the widespread conviction that they are very rare. Their role is actually largely underestimated, mainly because they often remain unrecognized and misidentified. Aiming to minimize such bias, emphasis has been placed on more common identification pitfalls. Together with new NTM, new members of the Mycobacterium tuberculosis complex described in the last few years are also an object of the present review.

A novel actinomycete strain, designated YIM M13705 T , was isolated from a marine sediment sample of the South China Sea and its characteristics were determined by a polyphasic approach. The slowly growing, Gram-stain-positive, aerobic strain produced branched substrate mycelium and aerial hyphae, and no diffusible pigment was produced on the media tested. At maturity, spore chains were formed on aerial hyphae and substrate mycelium was not fragmented. Whole-cell hydrolysates of the strain contained meso-diaminopimelic acid and galactose, glucose, ribose and rhamnose. The predominant menaquinones were MK-9(H 4 ) and MK-10(H 2 ). The polar lipids detected were diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol and ninhydrin-positive phosphoglycolipids. The major fatty acid was iso-C 16 : 0 . The G+C content of the genomic DNA was 68.2 mol%. On the basis of 16S rRNA gene sequence, the strain was shown to be most closely related to species of the genus Actinophytocola. DNA-DNA hybridization relatedness values (,70 %) of the isolate with its closest neighbour Actinophytocola xinjiangensis QAIII60 T supported classification of the isolate as a representative of a novel species. On the basis of phylogenetic analysis, and phenotypic and genotypic data, it is concluded that the new isolate belongs to a novel species of the genus Actinophytocola, for which the name Actinophytocola sediminis sp. nov. (type strain YIM M13705 T 5DSM 45939 T 5BCRC 16956 T ) is proposed.

“…Non-tuberculous mycobacteria (NTM) are environmental and opportunistic pathogens. Recent advancements in DNA sequencing techniques have led to the identification of various new NTM species [1–5]. The universalized species identification techniques used in clinical laboratories also facilitates the discovery of novel NTM species [6, 7].…”

Mycobacterium vicinigordonae sp. nov., a slow-growing scotochromogenic species isolated from sputum

A slow-growing, scotochromogenic mycobacterial strain (24T) was isolated from the sputum of a Chinese male human. Phylogenetic analysis using the 16S rRNA gene assigned strain 24T to the Mycobacterium gordonae complex, which includes Mycobacterium gordonae and Mycobacterium paragordonae . The phenotypic characteristics, unique mycolic acid profile and the results of phylogenetic analysis based on hsp65 and rpoB sequences strongly supported the taxonomic status of strain 24T as a representative of a species distinct from the other members of the M. gordonae complex. The genomic G+C content of strain 24T was 65.40mol%. Genomic comparisons showed that strain 24T and M. gordonae ATCC 14470T had an average nucleotide identity (ANI) value of 81.00 % and a DNA–DNA hybridization (DDH) value of 22.80 %, while the ANI and DDH values between strain 24Tand M. paragordonae 49 061T were 80.98 and 22.80 %, respectively. In terms of phylogenetic, phenotypic and chemotaxonomic features, strain 24T is distinguishable from its closest phylogenetic relatives and represents a novel species of the genus Mycobacterium , therefore the name Mycobacterium vicinigordonae sp. nov. is proposed. The type strain is 24T (=CMCC 93559T=DSM 105979T).
