Mycobacteria

Surrounded by mycobacteria: nontuberculous mycobacteria in the human environment.

A majority of the Mycobacterium species, called the nontuberculous mycobacteria (NTM), are natural inhabitants of natural waters, engineered water systems, and soils. As a consequence of their ubiquitous distribution, humans are surrounded by these opportunistic pathogens. A cardinal feature of mycobacterial cells is the presence of a hydrophobic, lipid-rich outer membrane. The hydrophobicity o...

A Review on Environmental Mycobacteria in Iran

Abstract Mycobacterium genus, including pathogenic and environmental species, is called non-tuberculosis mycobacteria. In this review, we assessed the research about the frequency of non-tuberculosis mycobacteria in Iran. The analyses showed that there are 16 and 28 mycobacterial species isolated in water and soil samples, respectively. The most frequent mycobacterial species in water were M. f...

Immunity against mycobacteria.

Mycobacterium tuberculosis is the most prevalent infectious pathogen in the world, largely due to its unique interactions with the human immune system. Even in a normal host, a frequent outcome of infection with M. tuberculosis is failure to completely eradicate the organisms, despite the development of cell-mediated immunity. Viable organisms persist in a state in which they do not progressive...
