Objective(s): Tuberculosis (TB), a disease caused by Mycobacterium tuberculosis (Mtb), stayed a global health thread with high mortality rate. Since TB has a long-term treatment, it leads high risk of drug resistant development, and there is an urgent to find new drugs. The aim of this study was designing new inhibitors for a new drug target, iron dependent regulator, IdeR. Materials and Method...

A mixed infection of Mycobacterium abscessus subsp. abscessus (Mab) and Mycobacterium tuberculosis (MTB) in the lung is an unusual clinical manifestation and has not yet been reported. A 61-year-old woman had been treated for Mab lung disease and concomitant pneumonia, and was diagnosed with pulmonary tuberculosis (PTB). Despite both anti-PTB and anti-Mab therapy, her entire left lung was destr...

An estimated third of the world's population is latently infected with Mycobacterium tuberculosis (Mtb), with no clinical signs of tuberculosis (TB), but lifelong risk of reactivation to active disease. The niches of persisting bacteria during latent TB infection remain unclear. We detect Mtb DNA in peripheral blood selectively in long-term repopulating pluripotent hematopoietic stem cells (LT-...

CD4(+) T cells are prominent effector cells in controlling Mycobacterium tuberculosis (Mtb) infection but may also contribute to immunopathology. Studies probing the CD4(+) T cell response from individuals latently infected with Mtb or patients with active tuberculosis using either small or proteome-wide antigen screens so far revealed a multi-antigenic, yet mostly invariable repertoire of immu...

Objective: To compare the yield from Gastric lavage (GL) and Broncho alveolar lavage (BAL) samples in adult patients suspected case of Tuberculosis but not producing sputum. Methodology: 80 adults with suspected case of tuberculosis but not producing sputum were recruited. 72 patients were then subjected to one gastric lavage followed by Broncho-alveolar lavage in the same morning. The collecte...

Immunocompromised patients with acid-fast bacilli (AFB) smear-negative active pulmonary tuberculosis (pTB) often present with nonspecific clinical symptoms and findings. T-cell interferon-gamma release assays (TIGRA) performed on whole blood (using ELISA) or peripheral blood mononuclear cells (using enzyme-linked immunospot assay (ELISPOT)) are more sensitive for the diagnosis of Mycobacterium ...

In article number 2100453 by Steffen Stenger, Mika Lindén, and co-workers, the activity of antimicrobial peptide NapFab against intracellular Mycobacterium tuberculosis (Mtb) is significantly increased loading onto dendritic mesoporous silica nanoparticles (DMSN). This enhanced based on a 30-fold increased, DMSN-mediated uptake. Livecell fluorescence microscopy electron reveal fast DMSN uptake ...

Background: Long-term exposure to silica dust makes people prone for silicosis which raises the risk of individual in developing pulmonary tuberculosis (PTB). Silicosis is a progressive lung disease characterize with shortness breath, cough, fever, and bluish skin, caused due inhalation crystalline found abundance sand, rock, quartz. Aims Objectives: The known effect functioning macrophages mak...

The standard treatment of tuberculosis (TB) takes six to nine months to complete and this lengthy therapy contributes to the emergence of drug-resistant TB. TB is caused by Mycobacterium tuberculosis (Mtb) and the ability of this bacterium to switch to a dormant phenotype has been suggested to be responsible for the slow clearance during treatment. A recent study showed that the replication rat...

Mycobacterium tuberculosis (MTB) is one of the most successful pathogens in human history and remains a global health challenge. MTB has evolved a plethora of strategies to evade the immune response sufficiently to survive within the macrophage in a bacterial-immunological equilibrium, yet causes sufficient immunopathology to facilitate its transmission. This review highlights MTB as the driver...
