'Conversation stoppers' fight deadly bacterial infections
Bacterial infections are becoming more deadly worldwide due to increased resistance to antibiotics. Now, chemists at the University of Wisconsin-Madison have developed a powerful strategy to fight these deadly infections: Instead of killing the bacteria directly, the scientists designed a group of compounds that can block the chemical signals that... view more...

UC San Diego Bioengineers Fill Holes in Science of Cellular Self-Organization
The chemical and biological aspects of cellular self-organization are well-studied; less well understood is how cell populations order themselves biomechanically - how their behavior and communication are affected by high density and physical proximity. view more (2008-10-07)
Unusual microbial ropes grow slowly in cave lake
Deep inside the Frasassi cave system in Italy and more than 1,600 feet below the Earth's surface, divers found filamentous ropes of microbes growing in the cold water, according to a team of Penn State researchers. view more (2008-12-22)
An Antimicrobial Solution For Blocked Urinary Catheters? (p 1435)
Authors of a research letter in this week's issue of THE LANCET propose a new method for inflating urinary catheters-which could avoid common problems of encrustration and blockage of the catheter. Urinary catheters are usually inflated with water, but this often results in bacterial build-up leading to catheter encrustration and blockage. David... view more... (2003-04-23)
Antibacterial coatings cut infection rates
Putting antibacterial coatings on hip and knee implants and biomedical devices such as catheters could cut infection rates following surgery and significantly reduce health care costs and improve quality of life for patients. view more (2005-11-30)
Research highlights how bacteria produce energy
The world's smallest life forms could be the answer to one of today's biggest problems: providing sustainable, renewable energy for the future. view more (2006-05-22)
Cool plasma packs heat against biofilms
Though it looks like a tiny purple blowtorch, a pencil-sized plume of plasma on the tip of a small probe remains at room temperature as it swiftly dismantles tough bacterial colonies deep inside a human tooth. view more (2009-06-11)
Grant award for First Study of Emerging Yeast Species
An emerging species of yeast, Candida parapsilosis is causing increasing numbers of infections because it spreads easily from medical devices into the blood stream of patients. Science Foundation Ireland has recently awarded almost EUR1 million to Dr. Geraldine Butler of the Conway Institute of Biomolecular and Biomedical Research, Dublin for her... view more...

Putting a stop to antibiotic resistance with new drugs from seaweed
Scientists have found a new way to prevent life-threatening infections not by killing the bacteria but by preventing them from talking to each other, according to research published today in the journal Microbiology. We`ve found that a group of chemicals called furanones can prevent the build up of communities of bacteria on surfaces such as... view more... (2001-12-21)
Appendix isn't useless at all: It's a safe house for bacteria
Long denigrated as vestigial or useless, the appendix now appears to have a reason to be - as a "safe house" for the beneficial bacteria living in the human gut. view more (2007-10-09)
Cranberries contain possible anti-caries/anti-plaque agents
Scientists have discovered that the humble cranberry harbors several anti-oxidants (flavonoids) that show the ability to counteract the damaging effects of the bacterium Streptococcus mutans, which causes dental caries (tooth decay). view more (2006-06-29)
Brush anode and tubular cathode scale up microbial fuel cells
Generating electricity from renewable sources will soon become as easy as putting a brush and a tube in a tub of wastewater. view more (2007-03-22)
Single gene lets bacteria jump from host to host
All life - plants, animals, people - depends on peaceful coexistence with a swarm of microbial life that performs vital services from helping to convert food to energy to protection from disease. view more (2009-02-02)
New method monitors critical bacteria in wastewater treatment
Researchers have developed a new technique using sensors to constantly monitor the health of bacteria critical to wastewater treatment facilities and have verified a theory that copper is vital to the proper functioning of a key enzyme in the bacteria. view more (2009-02-05)
Bacteria that cause urinary tract infections invade bladder cells
Scientists at Washington University School of Medicine in St. Louis have found definitive proof that some of the bacteria that plague women with urinary tract infections (UTIs) are entrenched inside human bladder cells. view more (2007-12-18)
Making hospitals safer from infection
"One small water line feeding one hospital faucet alone can house millions of bacteria," said international Legionella expert Janet Stout, Ph.D., urging public health and infection control officers to be proactive against Legionella and other waterborne microbes that contribute to soaring hospital infection rates. view more (2007-12-21)
Should dentists worry about vCJD transmission?
Existing guidelines on treating patients with diseases such as Creutzfelt-Jakob disease (CJD) do not cover dental health in any detail. Writing in the April Journal of the Royal Society of Medicine, Professor Stephen Porter of the Eastman Dental Institute at the University of London suggests "important modifications" to the current infection... view more...

Winemaking waste proves effective against disease-causing bacteria in early studies
A class of chemicals in red wine grapes may significantly reduce the ability of bacteria to cause cavities, according to a study published recently in the Journal of Agricultural and Food Chemistry. view more (2008-01-03)
Novel plague virulence factor identified
Researchers at Duke University Medical Center have identified a previously unknown family of virulence factors that make the bacterium responsible for the plague especially efficient at killing its host. view more (2005-08-29)
Living sensor can warn of arsenic pollution
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at... view more...
