10 de jun. de 2019 · INTRODUCTION. Tuberculosis (TB) is a leading cause of mortality in the world today and is caused by the bacterial pathogen Mycobacterium tuberculosis.Despite innovations in diagnostics and improved access to health care, the global burden of TB remains substantial with around 10 million new cases of infection and 1.6 million deaths reported due to TB in 2017 alone (WHO 2018).
Abstract. Mycobacterium tuberculosis remains one of the most successful bacterial pathogens, claiming over 1.3 million lives worldwide in 2013. The emergence of multidrug-resistant and extensively drug-resistant isolates has prompted the need for new drugs and drug targets. M. tuberculosis possesses an unusual cell wall dominated by lipids and ...
11 de ago. de 2021 · The pathogen Mycobacterium tuberculosis ( Mtb ), causing tuberculosis disease, features an extraordinary thick cell envelope, rich in Mtb- specific lipids, glycolipids, and glycans. These cell wall components are often directly involved in host-pathogen interaction and recognition, intracellular survival, and virulence.
5 de dic. de 2012 · Introduction. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains of Mycobacterium tuberculosis (Mtb) are emerging at alarming rates (Fauci, 2008).A possible reason for this is poor patient compliance with existing treatments, which require multiple drugs to be taken daily for at least 6 months (Medical Section of the American Lung Association, 1997) to eliminate the ...
1 de feb. de 2003 · Much of the early structural definition of the cell wall of Mycobacterium spp. was initiated in the 1960s and 1970s. There was a long period of inactivity, but more recent developments in NMR and mass spectral analysis and definition of the M. tuberculosis genome have resulted in a thorough understanding, not only of the structure of the mycobacterial cell wall and its lipids but also the ...
Here, we demonstrate that SQ109 disrupts cell wall assembly, as evidenced by macromolecular incorporation assays and ultrastructural analyses. SQ109 interferes with the assembly of mycolic acids into the cell wall core of Mycobacterium tuberculosis, as bacilli exposed to SQ109 show immediate inhibition of trehalose dimycolate (TDM) production and fail to attach mycolates to the cell wall ...
