New results from a safety and immunogenicity study, which included a challenge phase to test efficacy, indicate that a live attenuated enterotoxigenic Escherichia coli (ETEC) vaccine candidate, given in combination with a novel adjuvant, provided significant protection against disease. This repr... Read More
It may come as a bit of a surprise to learn that bacteria have an immune system - in their case to fight off invasive viruses called phages. And like any immune system - from single-celled to human - the first challenge of the bacterial immune system is to detect the difference between "foreign"... Read More
Bacteria are as individual as people, according to new research by Professor Peter Young and his team in the Department of Biology at the University of York. Bacteria are essential to health, agriculture and the environment, and new research tools are starting to shed more light on them.

Engineered E. coli can store long-term memories of chemical exposure, other events in their DNA.
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well su... Read More
For patients who acquire an infection while in the hospital, each day of hospitalization increases the risk that the infection will be caused by a drug-resistant ... Read More
When scientists launch a spacecraft into space, they're also launching thousands of bacteria along with it.
This article was originally published in the January 2015 issue of Popular Science.
To prepare the Curiosity rover for its trip to Mars, NASA scrubbed it with alcohol and baked it at... Read More
Is it possible that our personal hygiene routines make us too clean? Are we soaping and cleansing away friendly microbes that help preserve skin health? A study presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington, DC, provides food for thought o... Read More
For more than a year, Cornell University's Christopher Mason and his team of researchers have been identifying bacteria in the New York City subway system. And some of the findings might surprise you. Photo: Katie Orlinsky for The Wall Street Journal
Boston, MA -- Longer secondary schooling substantially reduces the risk of HIV infection--especially for girls--and could be a very cost-effective way to halt the spread of the virus, according to researchers from Harvard T.H. Chan School of Public Health. In a study in Botswana, researchers fou... Read More
Though western diets and modern-day hygiene have wiped a few dozen species right out of our digestive tracts, "it's not clear if more diversity in the microbiome is healthier." -- M. Gloria Dominguez-Bello, New York University School of Medicine. Read More
We can’t see them, but they are all around us. On us. In us. Our personal microbes—not to mention those in the environment around us—have us outnumbered by orders of magnitude, but scientists are only beginning to understand how they influence our health and other aspects of our lives. It’s an i... Read More
The time before the symptoms of a viral infection appear is called the incubation period. During this time, viral genomes are replicating and the host is responding, producing cytokines such as interferon that can have global effects, leading to the classical symptoms of an acute infection (e.g....

The arrival in the United States of a Liberian man infected with the Ebola virus shows how easily the disease can travel and how thin the procedures are, relying heavily on the honesty of travelers and the diligence of airport workers. Some experts say that the system, given its inherent weaknes... Read More
In the not too distant future each of us will be able to colonize our gut with genetically modified “smart” bacteria that detect and stamp out disease at the earliest possible moment. This scenario may sound like the premise for a sci-fi flick, but it is a very real possibility. Microbiome engin... Read More
Ed Yong, a freelance science writer who authors the Not Exactly Rocket Science blog for National Geographic, has penned an opinion piece in the NY Times Sunday Review on how society needs to start thinking about the microbiome as an ecosystem with all the complexities that it entails and not as ...

Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

Chagas disease - a parasitic infection that can cause severe heart disease and death if not caught and treated early - affects millions of people worldwide, mainly in Latin America. Now, new research suggests it is increasingly being seen in the southern US and poses an emerging potential public... Read More

Your gut is a genius. Inside it exists an astonishing ecosystem of trillions of micro-organisms—more than 10 times the number of human cells in our bodies! This ecosystem of microbes—the human gut microbiota—deeply influences our phy... Read More
"If you want to find unique diversity and if you want to find a wide range of different below-ground organisms, you don't have to travel around the world. You can walk across Central Park."
That statement comes from Noah Fierer, an ecology and evolutionary biology professor at the University ... Read More
