A non-virulent variant of the deadly Vibrio cholerae O1 strain has likely been present in Haitian aquatic environments for several hundred years, with the potential to become virulent through gene transfer with the toxigenic strain introduced by UN peacekeepers, according to research published t...

It’s difficult to make predictions, especially about the future, and even more so when they involve the reactions of living cells — huge numbers of genes, proteins and enzymes, embedded in complex pathways and feedback loops. Yet researchers at the University of California, Davis, Genome Center ... Read More
It’s like Jekyll and Hyde. One moment bacteria on the skin are harmless, the next they are causing a full-on spotty break out. Now researchers have discovered exactly why this happens – a breakthrough that could yield new acne treatments, possibly in two years.
Richard Gallo of the University... Read More
Hospital rooms, not just the patients in them, can spread germs through contact with health care personnel, a Duke Health study reports.
“This study is a good wake-up call that health care personnel need to concentrate on the idea that the health care environment can be contaminated,” said De... Read More
Halloween will soon be upon us, and we are once again surrounded by stories of supernatural occurrences, violent crimes, monsters, and ghouls (not to mention a few creepy clowns thrown in for good measure). But are these just stories? Are ghosts, witches, and zombies just figments of our imagina... Read More
Another folk medicine remedy bites the dust. Cranberry capsules didn't prevent or cure urinary infections in nursing home residents in a study challenging persistent unproven claims to the contrary.
The research adds to decades of conflicting evidence on whether cranberries in any form can pr... Read More
That twice-yearly trip to the dentist could do more than keep teeth and gums healthy: It may decrease the risk of pneumonia by reducing bacteria in the mouth, suggests research being presented at IDWeek 2016™.
Bacteria that commonly cause pneumonia include streptococcus, haemophilus, staphylo... Read More
Many microorganisms produce secondary natural products, the potential antibioticeffects of which are extensively investigated. German scientists have now examined a class of quinone-like substancescontaining an additional epoxide functional group for their antibiotic activities. As they report i... Read More
Playing classic video games like Pac-Man with living single-celled microbes thinner than a human hair is now possible thanks to an interactive microscope developed by bioengineers at Stanford University.
After several prototypes, the researchers released blueprints earlier this month for a "L... Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
Biofilms, surface-attached microbial communities encased in an extracellular matrix, are one of the most common macroscopic microbial structures we can see in nature. Biofilms like those seen in pond scum, in dental plaque, or in hot springs, are mixed communities with the members forming both a... Read More
Researchers have been trying for decades to develop a vaccine against the globally endemic hepatitis C virus (HCV). Now scientists at The Scripps Research Institute (TSRI) have discovered one reason why success has so far been elusive.
Using a sophisticated array of techniques for mapping tin... Read More
A new microscopic technique is enabling scientists to observe the antibiotic daptomycine live in action. This marks an exciting first, because even though doctors have been prescribing this antibiotic for over a decade, its precise mechanisms have remained unclear.
First, the scientists tagg... Read More
A microbe that ‘eats’ both methane and iron: microbiologists have long suspected its existence, but were not able to find it - until now. Researchers at Radboud University and the Max Planck Institute for Marine Microbiology in Bremen discovered a microorganism that couples the reduction of iron... Read More
Meet the Microbe Mafia: K. rhizophila, E. coli, and C. xerosis. They might seem like friendly bacteria but are always looking for opportunities to cause disease. Well ..... K. rhiz is really not that bad but peer pressure works in bacterial populations as well. When armed with C. violaceum th... Read More
Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More
Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for thousands of deaths around the world each year. However, because the bacteria are resistant to many different antibiotics, treatment options are limited, and often ineffective.
But until now scientists didn't know how MRSA ... Read More
The world has been galvanized by the Zika epidemic spreading through the Americas, which has left more than two thousand infants with severe brain damage. But for pregnant women and their infants in the United States, cytomegalovirus, or CMV, is the far greater viral threat.
Every year, 20,00... Read More
