Researchers discover role of H2S as defense mechanism against oxidative stress and antibiotics Although scientists have known for centuries that many bacteria produce hydrogen sulfide (H2S) it was thought to be simply a toxic by-product of cellular activity. Now, researchers at NYU School of Medicine have discovered H2S in fact plays a major role in protecting bacteria from the effects of numerous different antibiotics. In the study led by Evgeny Nudler, PhD, the Julie Wilson Anderson...

An experimental treatment for urinary tract infections has easily passed its first test in animals, alleviating weeks-long infections in mice in as little as six hours. "This drug can block the spread of the bacteria that cause urinary tract infections far better than any other previously reported compound," says senior author Scott J. Hultgren, PhD, the Helen L Stoever Professor of Molecular Microbiology at Washington University School of Medicine in St. Louis. "If it has similar effects...

Trend data follows release of first-of-its-kind 'drug resistance index' for superbugs New research suggests a pattern of outpatient antibiotic overuse in parts of the United States-- particularly in the Southeast --a problem that could accelerate the rate at which these powerful drugs are rendered useless, according to Extending the Cure, a project of the Center for Disease Dynamics, Economics & Policy. These findings come out just as the Centers for Disease Control and Prevention...

It has been the cause of infamous international foodborne disease outbreaks and yet it is the most studied bacterium in science, an essential part of the human digestive tract, and a backbone of the biotech industry. To enhance public understanding of the bacterium Escherichia coli, the American Academy of Microbiology brought together the nation's leading experts to consider and answer some of the most frequently asked questions about this multifaceted microorganism. "The story of E....

Study shows cranberry juice is better than extract at fighting bacterial infections With scientific evidence now supporting the age-old wisdom that cranberries, whether in sauce or as juice, prevent urinary tract infections, people have wondered if there was an element of the berry that, if extracted and condensed, perhaps in pill form, would be as effective as drinking the juice or eating cranberry sauce. A new study from researchers at Worcester Polytechnic Institute helps to answer that...

UK Survey Reveals Cell Phones Are Contaminated

New research has found that one in six British mobile phones is contaminated with traces of E. coli bacteria because people all too often go without washing their hands. The research was released ahead of Global Handwashing Day, which is this Saturday. Experts say the most likely reason for the bacteria found on so many gadgets is people are failing to properly wash their hands with soap and hot water after using the toilet. Furthermore, more than nine in ten mobile phones have some...

Hospital associated infections (HAI) are often in the headlines, but what is the burden of mortality, morbidity and costs due to HAIs? In this week's PLoS Medicine, Marlieke de Kraker, Peter Davey and Hajo Grundmann, on behalf of the BURDEN (Burden of resistance and disease in European nations) study group, report the results of a prospective clinical investigation into the societal burden of HAIs from 31 European countries. The researchers combined prospective data on the burden of...

A University of Illinois study that uses new technology to assess and compare the safety of radish, broccoli, and alfalfa sprouts concludes that the secret to keeping sprouts free of foodborne pathogens lies in industry's intense attention to cleanliness of seeds. "Once seeds have germinated, it's too late. Sprouts are extremely complex structures with a forest-like root system that conceals microorganisms. Just a few E. coli cells can grow to a substantial population during germination...

Klebsiella pneumoniae is a Gram-negative, non-motile, encapsulated, lactose fermenting, facultative anaerobic, rod shaped bacterium found in the normal flora of the mouth, skin, and intestines. It is the most important member of the Klebsiella genus of Enterobacteriaceae. It is naturally occurring in soil and about 30% of strains can fix nitrogen in anaerobic conditions. Hans Christian Gram developed the technique now known as Gram staining in 1884 to discriminate between K. pneumoniae and...

Escherichia coli is a Gram-negative rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms. Most strains are harmless; however, some such as O157:H7 can cause food poisoning in humans and are often responsible for product recalls. The normal flora of the gut normally contains the harmless strains and often provide K2 to the body. They are not always confined to the intestine and have the ability to survive briefly outside of the body. It grows easily...
