Nontuberculous mycobacteria (NTM) are environmental opportunistic pathogens of humans and animals that emerging with a serious public health impact particularly in individuals Acquired Immunodeficiency Syndromes. Recent scientific evidence is shifting from NTMs being known as traditional organisms to pathogenic both humans. In humans, factors attributable this rise have been linked mainly Human...

Mycobacterium simiae is a multidrug-resistant, slowgrowing, nontuberculous mycobacterium (NTM) that has been rarely reported as a cause of pulmonary infections and disseminated disease in immunocompromised hosts, especially in patients with advanced AIDS [1]. Nontuberculous mycobacterium infections caused by M simiae have increasingly been reported as a cause for cervical lymphadenitis in immun...

Mycobacterium iranicum is a new species of nontuberculous mycobacterium reported in 2013. Here, we describe the first whole-genome sequence of this species, that of M. iranicum strain UM_TJL, isolated from a patient in Malaysia.

Mycobacterium lentiflavum is a nontuberculous, slowly growing mycobacterium usually recognized as a contaminant. Here, we report a case of disseminated M. lentiflavum infection responsible for hemophagocytic lymphohistocytosis in a heart-transplanted man.

Mycobacterium szulgai is a rare pathogen. Nontuberculous mycobacteria usually produce disease in people with some kind of immunosuppression or another predisposing condition. A case of pulmonary Mycobacterium szulgai infection is described.

In recent years there has been an increase in the incidence of nontuberculous mycobacteriosis, particularly of Mycobacterium avium complex lung disease, among people without HIV infection in many countries [1]. In Japan, the estimated incidence rate of nontuberculous mycobacteriosis in the 1970s was around 1.0 per 100,000 populations, but by 2007 it had risen to about 5.8 per 100,000, the highe...

Mycobacterium abscessus is a ubiquitous, rapidly growing species of nontuberculous mycobacteria that colonizes organic surfaces and is frequently associated with opportunistic infections in humans. We report here the draft genome sequence of Mycobacterium abscessus strain M139, which shows genomic features reported to be characteristic of both Mycobacterium abscessus subsp. abscessus and Mycoba...

Mycobacterium phlei is a rapidly growing nontuberculous Mycobacterium species that is typically nonpathogenic, with few reported cases of human disease. Here we report the whole genome sequence of M. phlei type strain RIVM601174.

To determine whether plumbing could be a source of nontuberculous mycobacteria (NTM) infection, during 2007-2009 I isolated NTM from samples from household water systems of NTM patients. Samples from 22/37 (59%) households and 109/394 (28%) total samples yielded NTM. Seventeen (46%) of the 37 households yielded ≥1 Mycobacterium spp. isolate of the same species as that found in the patient; in 7...

Tuberculosis (TB) is an infectious and transmissible disease caused by Mycobacterium tuberculosis and closely related mycobacterial species (M. bovis, M. africanum, and M. microti). These species, obligate pathogens, compose what is known as the M. tuberculosis complex. Nontuberculous mycobacterial (NTM) species are mycobacterial species other than those belonging to the Mycobacterium tuberculo...
