Experiments in rhesus macaques show that changing the mode of administration of an existing vaccine yields “amazing” results in the fight against tuberculosis (TB). Share on PinterestDelivering the TB vaccine intravenously rather than intradermally may prove significantly more effective. Globally, TB is one of the top 10 causes of death and the leading cause of […]

What to know about pulmonary tuberculosis
Tuberculosis is a bacterial infection that can pass through the air between people. When it affects the lungs, the medical name for this is pulmonary tuberculosis. It can cause chest pain, severe coughing, and a range of other symptoms. Tuberculosis (TB) bacteria mainly grow in the lungs, but they can infect other parts of the […]
Scorpion venom compounds can kill dangerous bacteria
Researchers have managed to synthesize two scorpion venom compounds that are effective against some strains of highly infectious bacteria. The compounds are also unlikely to harm humans, the scientists reassure us.

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 […]
Lower respiratory tract infections: What to know
Lower respiratory tract infections are any infections in the lungs or below the voice box. These include pneumonia, bronchitis, and tuberculosis. A lower respiratory tract infection can affect the airways, such as with bronchitis, or the air sacs at the end of the airways, as in the case of pneumonia. In this article, we look […]
How do you read a TB skin test?
The purified protein derivative test confirms whether someone has had exposure to tuberculosis, a serious infectious disease. A positive test result indicates that the person may have a tuberculosis infection, but it does not necessarily mean that they have active tuberculosis. Tuberculosis, or TB, is a bacterial infection that can affect any part of the […]
Bibasilar atelectasis: Symptoms, causes, and complications
Atelectasis is a partial or total collapse of one or both of the lungs. It occurs when tiny air sacs in the lungs known as alveoli deflate. Bibasilar atelectasis is the collapse of the lowest lobes in both lungs. Bibasilar atelectasis can cause severe complications if left untreated. How doctors deal with it will vary […]
Rats better at diagnosing TB than standard tests
New research shows that rats can detect up to 70 percent more cases of tuberculosis in children than standard smear tests. The findings may help to treat a significant number of children who have previously been overlooked. Doctors need better tools to detect TB in children. The World Health Organization (WHO) say that tuberculosis (TB) […]
Drug resistance: Could these onions help us win the war?
Drug resistance has emerged as one of the biggest threats to public health, highlighting the dire need for new antibiotics and improvements to existing ones. A new study may have brought us one step closer to such a feat, after identifying a type of onion that may help to treat drug-resistant tuberculosis. Researchers reveal how […]
Drug resistance: WHO report ‘serious lack of new antibiotics’
A new report from the World Health Organization confirms that, worryingly, there are now limited treatment options for some of the most common drug-resistant infections, which highlights the desperate need for new antibiotics. The WHO say that there are not enough new drugs in the pipeline to help combat antimicrobial resistance. But despite this need, the […]
