Tuberculosis, caused by Mycobacterium tuberculosis, is a fatal infectious disease that prevails to be the second leading cause of death from a single infectious agent despite the availability of multiple drugs for treatment. The current treatment regimen involves the combination of several drugs for 6 months that remain ineffective in completely eradicating the infection because of several drawbacks, such as the long duration of treatment and the side effects of drugs causing non-adherence of patients to the treatment regimen. Autophagy is an intracellular degradative process that eliminates pathogens at the early stages of infection. Mycobacterium tuberculosis's unique autophagy-blocking capability makes it challenging to eliminate compared to usual pathogens. The present review discusses recent advances in autophagy-inhibiting factors and mechanisms that could be exploited to identify autophagy-inducing chemotherapeutics that could be used as adjunctive therapy with the existing first-line anti-TB agent to shorten the duration of therapy and enhance cure rates from multidrug-resistant tuberculosis (MDR-TB) and extreme drug-resistant tuberculosis (XDR-TB).

Prevalence and exposure variables of latent infection by mycobacterium tuberculosis in healthcare workers.

Objectives: To identify in the scientific literature the prevalence, diagnostic methods, and exposure variables of latent infection by Mycobacterium tuberculosis in healthcare workers.
Methods: An integrative review of the scientific literature based on the following review question: What are the available scientific evidence in the literature that address the prevalence of latent infection by Mycobacterium tuberculosis in healthcare workers and its association with possible risk factors among these workers?
Results: Being a physician or nurse, being older, and being male were generally associated with higher prevalences. The study also showed that interferon-gamma release assays were more commonly used as a diagnostic method compared to skin tests.

Tuberculosis (TB), caused by the bacterium (), is still a leading cause of mortality worldwide. Fifty-fungi from a marine-derived fungal library were screened for anti- activity, and an strain with strong anti- activity was found. Three known flavones, chlorflavonin (), dechlorflavonin (), and bromoflavone (), were isolated from this fungus.

(MTB) ESX-1, a type VII secretion system, is a key virulence determinant contributing to MTB's survival within lung mononuclear phagocytes (MNPs), but its effect on MNP recruitment and differentiation remains unknown. Here, using multiple single-cell RNA sequencing techniques, we studied the role of ESX-1 in MNP heterogeneity and response in mice and murine bone marrow-derived macrophages (BMDM). We found that ESX-1 is required for MTB to recruit diverse MNP subsets with high MTB burden.

Tuberculosis (TB) remains a major global threat, with 10 million new cases and 1.5 million deaths each year. In multidrug-resistant tuberculosis (MDR-TB), resistance is most commonly observed against isoniazid (INH) and rifampicin (RIF), the two frontline drugs.

The type II NADH-dehydrogenase enzyme in plays a critical role in the efficient functioning of the oxidative phosphorylation pathway. It acts as the entry point for electrons in the electron transport chain, which is essential for fulfilling the energy requirements of both replicating and nonreplicating mycobacterial species. Due to the absence of the type II NADH-dehydrogenase enzyme in mammalian mitochondria, targeting the type II NADH-dehydrogenase enzyme for antitubercular drug discovery could be a vigilant approach.
