Changed Route of Immunization Dramatically Improves Efficacy of TB Vaccine

January 01, 2020

Tuberculosis (TB), an ancient disease, is the leading infectious cause of death globally, yet the world’s only licensed TB vaccine, Bacille Calmette-Guerin (BCG), was developed a century ago. Given to infants via a needle placed just under the skin, BCG protects babies from a form of the disease called disseminated TB but is far less effective at preventing pulmonary TB, the major cause of illness and deaths, in teens or adults.

NIH Launches Large TB Prevention Trial for People Exposed to Multidrug-Resistant TB

June 25, 2019

A large clinical trial to assess treatments for preventing people at high risk from developing multidrug-resistant tuberculosis (MDR-TB) has begun. The study is comparing the safety and efficacy of a new MDR-TB drug, delamanid, with the decades-old TB drug isoniazid for preventing active MDR-TB disease in children, adolescents and adults at high risk who are exposed to adult household members with MDR-TB.

Immune Cells Play Unexpected Role in Early Tuberculosis Infection

June 05, 2019

A class of immune cells called innate lymphoid cells (ILCs) mediates the body’s initial defense against tuberculosis (TB), according to a report published online today in Nature. Boosting this response may provide a new approach to developing treatments and vaccines against TB, which causes more deaths worldwide than any other single infectious disease. The research was supported in part by the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health.

NIH Statement on World Tuberculosis Day, March 24, 2019

March 22, 2019

Tuberculosis (TB) is the world’s leading infectious cause of death. In the 137 years since Dr. Robert Koch’s discovery of Mycobacterium tuberculosis (Mtb), the bacterium that causes TB, as many as one billion people worldwide have died of TB disease. This year’s World TB Day theme is “It’s Time” to end tuberculosis once and for all. We at the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH, are committed to accelerating the cutting-edge research necessary to ending this ancient disease.

Tuberculosis Diagnosis in People with HIV Increases Risk of Death Within 10 Years

March 06, 2019

Among people with HIV in Latin America, those diagnosed with tuberculosis (TB) at an initial clinic visit were about twice as likely to die within 10 years as people not initially diagnosed with TB, according to findings from a large observational study. This increased risk persisted despite the availability of TB treatment and mirrored patterns seen previously in HIV-negative populations, according to research supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Temperature-Stable Experimental Tuberculosis Vaccine Enters Clinical Testing

January 23, 2019

Vaccinations have begun in a Phase 1 human clinical trial testing a freeze-dried, temperature-stable formulation of an experimental tuberculosis (TB) vaccine candidate. The trial is being conducted at the Saint Louis University School of Medicine Center for Vaccine Development and will enroll as many as 48 healthy adult volunteers aged 18 to 55 years. The experimental vaccine, called ID93, was developed by scientists at the Infectious Disease Research Institute (IDRI) in Seattle.

NIAID Releases Strategic Plan to Address Tuberculosis Research

September 26, 2018

WHAT:
Tuberculosis (TB) is the leading infectious cause of death worldwide, killing roughly 1.6 million people in 2017. In the past 200 years, TB claimed the lives of more than one billion people—more deaths than from malaria, influenza, smallpox, HIV/AIDS, cholera and plague combined.

NIH Statement on World Tuberculosis Day, March 24, 2018

March 22, 2018

In the 130 years since the discovery of Mycobacterium tuberculosis (Mtb)—the bacterium that causes tuberculosis (TB)—at least 1 billion people have died from TB. That death toll is greater than the combined number of deaths from malaria, smallpox, HIV/AIDS, cholera, plague and influenza. Today, in commemoration of World TB Day, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), renews and reinvigorates its commitment to the research needed to end this ancient scourge. 

NIH Experts Call for Transformative Research Approach to End Tuberculosis

March 09, 2018

A more intensive biomedical research approach is necessary to control and ultimately eliminate tuberculosis (TB), according to a perspective published in the March 2018 issue of The American Journal of Tropical Medicine and Hygiene. In the article, authors Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and Robert W.

Mycobacteria Use Protein to Create Diverse Populations, Avoid Drugs

May 31, 2017

Subgroups of tuberculosis (TB)-causing bacteria can persist even when antibiotics wipe out most of the overall population. The need to eliminate these persistent subpopulations is one reason why TB treatment regimens are so lengthy. Now, researchers have shown that a single protein allows mycobacteria to generate diverse populations that can avoid TB drugs. The protein may be a target for intervention; blocking it might result in less mycobacterial diversity and shorten TB treatment courses.

WHAT:
New research findings provide insight into the immune system pathways that may be key to developing an effective tuberculosis (TB) vaccine. The study, to be published Thursday in the journal Nature Communications, was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

NIH-Funded Researchers Find Signs TB Can Persist in Lungs Despite Treatment

September 06, 2016

It has been known that the microbe that causes TB, Mycobacterium tuberculosis, can persist in the lungs even after patient tissue samples test negative for the bacteria. In new research appearing in Nature Medicine, intramural researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, together with NIAID grantees, found through the use of positron emission tomography/computerized tomography (PET/CT) scanning that TB lesions can remain in the lungs long after treatment with antibiotics has been completed.

NIH Statement on World Tuberculosis Day

March 23, 2016

On World Tuberculosis (TB) Day 2016, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), reaffirms its commitment to researching ways to better understand, prevent, diagnose and treat TB. March 24 marks the day in 1882 when German microbiologist Robert Koch announced he had discovered Mycobacterium tuberculosis(Mtb), the bacterium that causes TB—an airborne disease that most often attacks the lungs.

Blood Test Can Predict Risk of Developing Tuberculosis

March 23, 2016

One-third of the world’s population is thought to be infected with Mycobacterium tuberculosis (Mtb), the bacterium that causes tuberculosis (TB), but just a small fraction ever develops symptomatic illness.
