A new class of peptides may neutralize the endotoxin that causes sepsis, offering a new therapeutic strategy against an often lethal systemic bacterial infection. The researchers from Germany and Spain detail their findings in the September 2010 issue of the journal Antimicrobial Agents and Che... Read More
A self-administered patch containing tiny microneedles may effectively deliver influenza virus-like particles through the skin and protect against potentially pandemic flu viruses such as H5N1. Researchers from the U.S. and abroad report their findings in the September 2010 issue of the journal... Read More
Antimicrobial peptides from the skin of frogs may protect against life-threatening, multidrug-resistant infections such as Pseudomonas aeruginosa say researchers from Italy. They detail their findings in the September 2010 issue of the journal Antimicrobial Agents and Chemotherapy.

At first glance, you might not think the fungus Candida albicans and the bacterium Enterococcus faecalis would have a lot in common, but mBio’s first Minireview reveals another story: these dissimilar pathogens both use pheromone signaling for mating and for pathogenesis. By probing the environ... Read More
The U.S. Coast Guard said a “reddish sheen” was reported on the water in the upper harbor of New York that has been identified as a red tide outbreak, an accumulation of bacteria whose dense concentration turns the affected water reddish brown.
The reddish color was reported at about 7 a.m. a... Read More
It was the fifth game of the 2009 Ohio State University football season, and offensive lineman Andy Miller cheered as the Buckeyes sprinted past the Indiana Hoosiers, 33-14, the fourth win of the year. The campus was brimming with excitement, yet for Miller the occasion was bittersweet.
"I wa... Read More
HMP DACC is the Human Microbiome Project's Data Analysis and Coordination Center. A major goal of the HMP is to look for correlations between changes in the microbiome and human health. The HMP DACC is the central repository for all HMP data. More information about the project can be found on th... Read More
World Science asked leading microbiologist Stephen P. Diggle to comment on a study on “backstabbing bacteria” reported in World Science and presented Sept. 6 at the fall meeting of the Society for General Microbiology in Nottingham, U.K. Diggle, a Royal Socie... Read More
Not drying your hands thoroughly after washing them, could increase the spread of bacteria and rubbing your hands whilst using a conventional electric hand dryer could be a contributing factor. Frequently people give up drying their hands and wipe them on their clothes instead, but hand-hygiene ... Read More
Researchers at the University of California, San Diego have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signaling molecules between organisms.... Read More
Cockroaches are repulsive, but they have in their brain up to nine molecules from which antibiotics could be produced.
These molecules apparently have the capacity to fight more than 90 percent of resistant bacteria such as staphylococcus aureus and E. coli, said researchers from the Universi... Read More
Cancer is a difficult disease to treat because it's a personal disease. Each case is unique and based on a combination of environmental and genetic factors. Conventional chemotherapy employs treatment with one or more drugs, assuming that these medicines are able to both "diagnose" and "treat" t... Read More
In 1980, a scientist looking at bone fragments under an ultraviolet microscope noticed the bones were glowing green—a hallmark of the antibiotic tetracycline. The drug latches onto calcium and gets deposited in bone. Nothing unusual. Except these bones were from a Nubian mummy buried 1,600 years... Read More
Jesse Bolton is a pretty buff guy. He's in the Navy, and a few mosquitoes don't scare him much. But he has seen what the bite of a malaria-carrying insect can do. One of his squadmates picked it up in Africa a few years ago.
That's why Bolton was sitting in a suite at the Residence Inn in Bet... Read More
The vaccine used to contain the recent swine flu pandemic was effective, but health authorities will need to ramp up the speed and volume of production during the next global outbreak, a World Health Organization official said Monday.
The WHO declared last month that the swine flu pandemic th... Read More
Hartz Mountain Corp. is voluntarily recalling 75,000 bags of dog treats after tests by the Food and Drug Administration found salmonella in the product.
The New Jersey-based pet food company is pulling out one lot of Hartz Naturals Real Beef Treats for Dogs. It said the 8-ounce bags of treats... Read More
Viruses are a curious lot. The standard drawing of the tree of life, the one you find on the inside back cover of biology textbooks, is divided into three branches: Archaea, Bacteria and Eukarya. Viruses don’t make it onto the page.
That makes sense, some scientists argue, because they’re no... Read More
A link between poor oral hygiene and increased risk of heart attack has long been suspected.
But until now nobody has been able to figure out exactly why not brushing regularly might bring one on.
Now a Bristol University dental scientist has discovered that a common bacteria responsible ... Read More
Patients admitted to hospital with serious burns often have infected wounds that must be treated quickly. Yet it can take three days for microbiological tests to identify the bacteria present and allow doctors to select the appropriate treatment.
Old-time medical students were taught to reco... Read More
