The vaccine is safe to give to people with tuberculosis disease and strengthens the immune system’s ability to attack the bacteria that cause the disease, a new study shows. Tuberculosis is an infectious disease caused by the tubercle...
by University of Oxford Structural study of antibiotic opens the way for new TB treatments Credit: Shutterstock Using cutting-edge genomic sequencing techniques, researchers at the University of Oxford have identified almost all the genomic variation that gives people resistance to 13 of the most common tuberculosis (TB) drug treatments. The Comprehensive Resistance Prediction for Tuberculosis International...

It’s as true in the realm of infectious disease as combat. And the University of Nebraska–Lincoln’s Limei Zhang subscribes to the maxim that best encapsulates it. “In order to fight your enemies, you have to know how your enemies survive and attack you,” said Zhang, associate professor of biochemistry. “That’s the fundamental question we are looking at.”...

(A) List of published TB 16-gene risk signature from Zak et al. (2016) where *** indicates the presence of a 30-gene signature from Leicester incipient, subclinical TB, and clinical TB from...

In their paper published in...

Credit: NIAID When Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis, infects a person, the body’s immune response is critical to how the disease will progress—either helping the body fight the bacterium or exacerbating the infection University of Maryland researchers discovered a way that Mtb can...
Two new studies have cast unprecedented light on disease processes in tuberculosis, identifying key genetic changes that cause damage in the lungs and drug treatment that could speed up recovery. Tuberculosis (TB) is a lung infection that has killed more humans than any other and until last year was the top infectious killer around the...
BARCELONA INSTITUTE FOR GLOBAL HEALTH (ISGLOBAL) The ‘Xpert Ultra’ molecular test has a greater capacity than its predecessor (‘Xpert MTB/RIF’) in detecting tuberculosis cases, either passively (i.e. people who attend the hospital with disease symptoms) or actively (searching for possible causes in the community among contacts of cases). This is the main conclusion of a...
Written by Tim Newman on March 24, 2021 — Fact checked by Alexandra Sanfins, Ph.D. March 24 is World Tuberculosis Day, so in today’s edition of our Medical Myths series, we will focus on some of the misunderstandings associated with tuberculosis (TB). We cover the role of genetics, treatment, transmission, and more. Design by Diego Sabogal TB is a bacterial infection....
