U.S. Safety Protocols Stopped TB in Imported Lab Monkeys From Spreading to Humans

Rigorous safety protocols prevented an outbreak of tuberculosis last year in lab monkeys imported to the United States from spreading to humans, a new report shows.

Overall, 26 cynomolgus macaque monkeys flown in from Southeast Asia to the United States for research purposes were confirmed to be infected with the Mycobacterium orygis germ, which causes a form of TB, researchers a...

AI May Equal Trained Staff in Spotting TB on Chest X-Rays

Artificial intelligence (AI) may help clinicians diagnose tuberculosis in parts of the world where radiologists are scarce, a new study suggests.

AI software successfully identified tuberculosis (TB) from cellphone photos of chest X-ray images, researchers reported at a European conference this week.

“We've shown that AI software is at least as good at detecting TB as a trai...

U.S. Tuberculosis Cases Rose in 2022: CDC

Tuberculosis cases climbed again in 2022, U.S. health officials announced Thursday.

“The message is loud and clear — TB is still here. For the second year in a row, TB disease cases in the U.S. have continued to rise,...

Troubling Signs TB Is Gaining Resistance Against Combo Antibiotics

New drugs may be needed to fight the deadliest form of tuberculosis, because it may no longer respond to current treatments.

An animal study by Johns Hopkins University researchers found that an approved antibiotic regimen may not work for TB meningitis due to multidrug-resistant str...

TB Cases Declined in U.S. During Pandemic

Reported cases of tuberculosis (TB) dropped significantly across the United States during the COVID-19 pandemic, but delayed or missed diagnoses may have contributed to the decline.

"Delayed or missed tuberculosis disease diagnoses are threatening the health of people with TB disease and the communities where they live," said Dr. Philip LoBue, director of the division of tuberculosis elim...

Could a TB Vaccine Protect the Elderly From Severe COVID?

Scientists suspect that a century-old tuberculosis vaccine might be able to protect older adultsagainst the worst ravages of COVID-19.

The Bacillus Calmette-Guérin (BCG) vaccine was first used in 1921, and is on the World Health Organization's list of essential medicines. More than 130 million babies worldwide receive this vaccine every year.

But it is also known to calm the immune...

Could the TB Vaccine Help Prevent COVID-19?

A widely used tuberculosis vaccine may help protect people against the new coronavirus or reduce the severity of COVID-19, a new study suggests.

The Bacillus Calmette-Guérin (BCG) was developed in the early 1900s and is given to more than 100 million children worldwide every year.

In the United States, BCG is approved as a vaccine for people at high risk of contracting tuberculosis...

Evidence Mounts That TB Vaccine Might Help Protect Against COVID-19

A tuberculosis vaccine may help reduce the risk of death from COVID-19, researchers suggest.

Developing countries have lower-than-expected COVID-19 death rates, and a TB vaccine given in countries with high rates of tuberculosis might play a significant role in reducing COVID-19 death rates, according to authors of a new study.

The vaccine, which is routinely given to childr...

New Weapon in Fight Against Multidrug-Resistant TB

While the world's focus is trained on the new coronavirus, a groundbreaking clinical trial finds researchers battling a tough-to-treat form of an "old" infectious disease, tuberculosis.

TB is a bacterial infection that usually attacks the lungs. The disease does not get much attention in wealthy nations, where it's less common. The United States saw about 9,000 cases in 2018, accordin...

Imaging Scans May Lead to Shorter TB Treatment

A new monitoring approach could help improve treatment of patients with tuberculosis (TB), researchers say.

TB is an infectious disease that primarily affects the lungs. Treatment involves multiple pills or injection drugs daily for at least six months. Successful treatment depends on the medications reaching pockets of TB bacteria in the lungs.

Researchers have developed a ...

TB Vaccine More Powerful When Given Intravenously

The tuberculosis (TB) vaccine is far from infallible, but new animal research suggests the problem is not the vaccine but how it is delivered.

When given to monkeys intravenously rather than as an injection, the vaccine was much more effective, researchers from the University of Pittsburgh and the U.S. National Institute of Allergy and Infectious Diseases found.

"The effect...

Childhood TB Shot May Offer Long-Term Protection from Lung Cancer

A tuberculosis vaccine commonly used in other parts of the world might reduce a person's risk of developing lung cancer if given early in childhood, a six-decade-long study reports.

The Bacille Calmette-Guerin (BCG) vaccine is the only vaccine approved for preventing tuberculosis (TB) -- a potentially fatal infectious disease that typically attacks the lungs. Because TB risk is low i...

TB Cases Drop Among the Young, But Racial Disparities Persist

There's good and bad news in a new report on tuberculosis rates among American children and teens: Overall, the number of cases have fallen by nearly half, but they still remain much higher among minorities than whites.
