A Michigan State University research team is the first to show how a common bacterium found in improperly cooked chicken causes Guillain-Barre Syndrome (GBS). The federally funded research, now published in the Journal of Autoimmunity, not only demonstrates how this food-borne bacterium, known as Campylobacter jejuni, triggers GBS, but offers new information for a cure. If chicken isn't cooked to the proper minimum internal temperature, bacteria can still exist.

New genetic research from an international team including McMaster University, University of Helsinki, Vilnius University and the University of Sydney, suggests that smallpox, a pathogen that caused millions of deaths worldwide, may not be an ancient disease but a much more modern killer that went on to become the first human disease eradicated by vaccination.

Bacterial resistance does not come just through adaptation to antibiotics, sometimes the bacteria simply go to sleep. An international team of researchers is looking at compounds that attack bacteria's ability to go dormant and have found the first oxygen-sensitive toxin antitoxin system.

Many infectious pathogens are difficult to treat because they develop into biofilms, layers of metabolically active but slowly growing bacteria embedded in a protective layer of slime, which are inherently more resistant to antibiotics. Now, a group of researchers at Caltech and the University of Oxford have made progress in the fight against biofilms. Led by Dianne Newman, the Gordon M. Binder/Amgen Professor of Biology and Geobiology, the group identified a protein that degrades and inhibits biofilms of Pseudomonas aeruginosa, the primary pathogen in cystic fibrosis (CF) infections.

Every 18 seconds someone dies from tuberculosis (TB). It is the world's most deadly infectious disease. Mycobacterium tuberculosis, the causative agent of TB, has infected more than one-third of the entire human population with an annual death toll of approximately 1.5 million people. For the first time, an international team of scientists from Monash University and Harvard University have seen how, at a molecular level, the human immune system recognizes TB infected cells and initiates an immune response. Their findings, published in Nature Communications, are the first step toward developing new diagnostic tools and novel immunotherapies.

Australian researchers have found a new way to make one of the most common medical procedures in the world - placing drips or intravenous (IV) lines - safer, less painful and potentially more cost effective. The researchers, who were funded by the Emergency Medicine Foundation of Australia (EMF), found that using medical skin glue to hold hospital drips in place significantly reduced the need to replace them due to infection, pain, blockage or falling out.
