Pathogenic bacteria have evolved a variety of mechanisms to avoid being killed by the immune systems of the humans and animals they invade.
Among the most sophisticated is that practised by mycoplasmas, which regularly change their surface proteins to confuse the immune system. Recent work i... Read More
The Irish are genetically distinct from other Europeans – including their British neighbours. That's according to the first genome of an Irish person to be sequenced, which turns out to have a host of unusual genetic variations.
Brendan Loftus of University College Dublin, who led the team re... Read More
The peanut industry executive whose filthy processing plants were blamed in a salmonella outbreak two years ago that killed nine people and sickened hundreds more is back in the business.
Stewart Parnell, former president of the now-bankrupt Peanut Corp. of America, is working as a consultant... Read More
Microbes could be threatening our cultural heritage by degrading historic cinematographic film and even preventing some valuable footage to be archived at all.
Mr Gavin Bingley who is presenting his work at the Society for General Microbiology's autumn meeting in Nottingham describes how fung... Read More

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
