Tuberculosis

Tuberculosis (TB) is a bacterial infection caused by a germ called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes or talks. If you think you have been exposed, you should go to your doctor for tests as soon as possible. You are more likely to get TB if you have a weak immune system.

What is Tuberculosis?

Tuberculosis (TB) is a dreaded bacterial infection. It has been known to mankind since ancient ages. It was commonly called “consumption” at the turn of the last century because of the way the disease seemed to “consume” the individual it affected.

Frozen in time: Ancient bacteria reveal evolution of drug resistance

Bacteria have evolved to adapt to all of Earth's most extreme conditions, from scorching heat to temperatures well below zero.

Obesity sharply increases hospitalisation risk from infections, global analysis shows

Adult obesity is associated with a substantially higher risk of severe hospital-treated or fatal infections across multiple pathogens, with risk increasing as obesity severity rises. Global modelling suggests roughly one in ten infection-related deaths worldwide may be attributable to adult obesity, although causality cannot be confirmed.

Modified peptides show promise against tuberculosis bacteria

Antibiotic treatments are losing effectiveness against a range of common bacterial pathogens, including E. coli, K. pneumoniae, Salmonella and Acinetobacter, according to a warning issued by the World Health Organization last October.

Engineered Listeria boosts innate immunity against cancer

After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, Daniel Portnoy and his colleagues have discovered a way to turn the bacteria into a potent booster of the immune system - and a potential weapon against cancer.

High adherence and safety found in short TB treatments

A study comparing one- and three-month antibiotic treatments to prevent active tuberculosis (TB) finds that a high percentage of patients successfully completed both regimens and suffered few adverse side effects.

Obesity drives one in ten infectious disease deaths

Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study led by a University College London (UCL) researcher.

Early tuberculosis treatment reduces sepsis deaths in HIV patients

Sepsis is a leading global cause of hospital deaths, occurring when the body's response to infection damages tissue and causes organs to fail. Africa bears the world's highest burden of sepsis, with an estimated 48 million cases each year leading to about 11 million deaths.

Early TB treatment before sepsis diagnosis could save countless lives

Tuberculosis (TB) is a major unrecognized cause of deadly sepsis among people with HIV in Africa, a sweeping new study reveals. Beginning treatment for TB immediately – even before sepsis patients are diagnosed with TB – could save countless lives, the researchers say.

Immune dysfunction persists after combined TB and HIV therapy

The immune system remains seriously out-of-whack – in an inflammatory state of overactivation and impaired functionality – following the international gold standard for treating people with latent tuberculosis (TB) and HIV, a team at Texas Biomedical Research Institute reports in Nature Communications.

Age-tailored therapies needed for treating the young and old with sepsis

Dealing with an infection isn't as straightforward as simply killing the pathogen. The body also needs to carefully steer and monitor its immune response to prevent collateral damage.

Study reveals how tuberculosis exploits immune defenses to promote infection

Scientists have made a discovery that helps explain why humans and animals are so susceptible to contracting tuberculosis(TB) – and it involves the bacteria harnessing part of the immune system meant to protect against infection.

Key protein in the tuberculosis bacterium helps protect itself from foreign DNA

Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), have discovered how a key protein in the tuberculosis bacterium helps protect it from the influence of foreign DNA inserted into its genome.
