Self-destruction system in TB bacteria may lead to ‘perfect drug’

New research explores the structure of a natural self-destructive mechanism contained in the bacterium that causes tuberculosis in humans. Exploiting this mechanism using these new findings may soon lead to better treatments. Scientists move closer to the ‘perfect TB drug,’ after zooming in on the bacterium that causes it. In the United States, more than […]


Tuberculosis drug may work better than others in its class

Computer simulations suggest moxifloxacin outperforms two other drugs when doses are missed. Treatment of tuberculosis involves a combination of several drugs, sometimes including drugs from a class known as fluoroquinolones. Using computer simulations, scientists have shown that the fluoroquinolone known as moxifloxacin may be superior to two other commonly used fluoroquinolones, according to a new […]


Bacteria from cystic fibrosis patient could help thwart antibiotic-resistant TB

The number of drug-resistant tuberculosis (TB) cases is rising globally. But a newly discovered natural antibiotic – produced by bacteria from the lung infection in a cystic fibrosis patient – could help fight these infections. Lab testing reported in the Journal of the American Chemical Society shows that the compound is active against multi-drug resistant […]


Tuberculosis skin test: What to expect

Tuberculosis is an airborne disease caused by an infection of the Mycobacterium tuberculosis bacteria. A TB skin test is the first method a doctor will use to try to determine if a person has TB. This article explores what happens during a TB skin test, what the results might mean, and what to do once […]

A doctor’s life-enhancing experience of working on a humanitarian TB project

Dr. Mark McNicol, a middle grade specialty doctor from Northern Ireland, recently spent 9 months working for Medicines Sans Frontières/Doctors Without Borders. In an interview with Medical News Today, he explains that the stigma of disease and the suffering of sick people living in poverty made a significant impression on him while treating patients […]
