Triclosan, often maligned, may have a good side — treating cystic fibrosis infections

Antibiotic-resistant bacteria inside a biofilm. Kateryna Kon/ Chris Waters, Michigan State University Maybe you’ve had the experience of wading in a stream and struggling to keep your balance on the slick rocks, or forgetting to brush your teeth in the morning and feeling a slimy coating in your mouth. These are examples of bacterial biofilms that are found anywhere a surface is exposed to bacteria in a moist environment. Besides

Gut check: Swallowed capsule could spot trouble, send alert

(AP) Scientists have developed a swallowed capsule packed with tiny electronics and millions of genetically engineered living cells that might someday be used to spot health problems from inside the gut. The capsule was tested in pigs and correctly detected signs of bleeding, researchers at the Massachusetts Institute of Technology reported Thursday in the journal Science . At more than an inch long, it will have to be made smaller

Confronted with bacteria, infected cells die so others can live, Penn study finds

The immune system is constantly performing surveillance to detect foreign organisms that might do harm. But pathogens, for their part, have evolved a number of strategies to evade this detection, such as secreting proteins that hinder a host's ability to mount an immune response. In a new study, a team of researchers led by Igor E. Brodsky of the University of Pennsylvania, identified a "back-up alarm" system in host cells

Nova Southeastern University Researchers Studying How to Disrupt Bacteria to Treat Infections

Bacteria are everywhere. And despite widespread belief, not all bacteria are “bad.” However, to combat those that can cause health issues for humans, there has been an over-reliance on the use of antibiotics – so much so, that many of them are now proving ineffective due to bacteria developing increased resistance to them. “More and more antibiotics are essentially becoming useless,” says Robert Smith, Ph.D., assistant professor in the Department

Improved Pneumonia Treatment Focus Of Current MSU Research

Streptococcus pneumoniae likely is not a term immediately recognizable by most individuals, even if they have had unpleasant run-ins with the common bacterium. However, experts at Mississippi State University are pioneering pathways to new treatment options. Primarily affecting those at opposite ends of a typical lifespan, it can cause ear infections in young children and serious cases of pneumonia in adults over 65. While illnesses caused by the bacterium can

Deadly Bacteria Share Weapons to Outsmart Antibiotics

Bacteria are rapidly developing resistance mechanisms to combat even the most effective antibiotics. Each year in the United States over 23,000 people die as a result of bacterial infections that have no treatment options, according to the Centers for Disease Control. Infections with antibiotic-resistance bacteria are extremely difficult to treat, requiring costly or toxic medications that do not always work. Scientists are constantly working to understand the mechanisms bacteria use

Looking at the Bacteria Inside: A New Method of Viewing TB Bacteria

Although tuberculosis (TB) is commonly thought of as being a disease that mainly affects nineteenth century poets and Victor Hugo characters, it is still the second-most common cause of mortality from an infectious disease in the world, killing nearly three people every minute. Every March 24, on World TB Day, the global health community recognizes the work of Robert Koch, who announced on that date in 1882 his discovery of
