Skin microbiota may help protect the body from infection

A research team at the National Institutes of Health has found that bacteria that normally live in the skin may help protect the body from infection. As the largest organ of the body, the skin represents a major site of interaction with microbes in the environment.

Molecular explanation for increased susceptibility to intestinal inflammation in malnutrition

More than one billion people in poor countries are starving, and malnutrition remains a major problem even in rich countries, making it a leading cause of death in the world. For over a hundred years, doctors have known that a lack of protein in the diet or low levels of amino acids, the building blocks of proteins, can lead to symptoms like diarrhoea, inflamed intestines and other immune system disorders, which weaken the body and can be fatal. However, the molecular mechanism which explains how malnutrition causes such severe symptoms has been largely unexplored.

Tips to prevent illness in crowds

Massive crowds from around the globe will mingle in London during the Olympics, and that means a world-class array of germs will mix with them. Mayo Clinic infectious diseases expert Gregory Poland, M.D., offers several tips for avoiding illness when you are around lots of people, whether at the Olympics, a professional football game, convention, arena concert or other major event.

How an opportunistic fungal pathogen knows when to attack

The opportunistic fungal pathogen Candida albicans inconspicuously lives in our bodies until it senses that we are weak, when it quickly adapts to go on the offensive. The fungus, known for causing yeast and other minor infections, also causes a sometimes-fatal infection known as candidemia in immunocompromised patients. An in vivo study, published in mBio, demonstrates how C. albicans can distinguish between a healthy and an unhealthy host and alter its physiology to attack.

New combination therapy for TB shows promise in Phase II study

"Results from a groundbreaking trial of three drugs given in combination -- one of them completely new and one not yet licensed for this use -- killed more than 99 percent of patients' [tuberculosis (TB)] bacteria after two weeks of treatment," and the combination "appears to be equally effective on drug-resistant TB," the Guardian reports.

Novel combination drug regimen could be more effective than existing treatments for TB

A novel approach to discover the first new tuberculosis (TB) combination drug regimen cleared a major hurdle when Phase II clinical trial results found it could kill more than 99 percent of patients' TB bacteria within two weeks and could be more effective than existing treatments, according to a study published today in the Lancet.

TB combination drug trials progress

A novel approach to discover the first new tuberculosis (TB) combination drug regimen cleared a major hurdle when Phase II clinical trial results found it could kill more than 99 percent of patients’ TB bacteria within two weeks and could be more effective than existing treatments, according to a study published today in the Lancet. These results add to a growing body of evidence that the new regimen could reduce treatment by more than a year for some patients.

Experts examine host recognition of Staphylococcus and E.coli bacteria

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often completely unnoticeable elimination of the invaders. Their immune-activating abilities were only detected in 1998, a discovery which was awarded with the Nobel Prize
