Like other bacterial species, Mycobacterium tuberculosis has multiple sigma (σ) factors
encoded in its genome. In previously published work, we and others have shown that …

The numerous sigma (σ) factors present in Mycobacterium tuberculosis are indicative of the
adaptability of this pathogen to different environmental conditions. In this report, we describe …

In previously published work, we identified three Mycobacterium tuberculosis sigma (σ)
factor genes responding to heat shock (sigB, sigE and sigH). Two of them (sigB and sigE) …

Mycobacterium tuberculosis is one of the most successful pathogens of humankind. During
infection, M. tuberculosis must cope with and survive against a variety of different …

Rapid adaptation to changing environments is one of the keys of the success of
microorganisms. Such adaptation is achieved by enabling different strategies, the most …

The extracytoplasmic factor (ECF) sigma factor σE is one of the most studied sigma factors of
Mycobacterium tuberculosis. It has been shown to be involved in virulence as well as in …

The ability of Mycobacterium tuberculosis to adapt to different environments in the infected
host is essential for its pathogenicity. Consequently, this organism must be able to modulate …

One of the important determinants of virulence of Mycobacterium tuberculosis is adaptation
to adverse conditions encountered in the host cells. The ability of Mycobacterium to …

Mycobacterium tuberculosis is a remarkable pathogen capable of adapting and surviving in
various harsh conditions. Correct gene expression regulation is essential for the success of …

Tuberculosis remains a worldwide threat despite the availability of the BCG vaccine and
antibiotic treatment. It is estimated that its etiologic agent, Mycobacterium tuberculosis …
