El tratamiento de aguas residuales en comunidades pequeñas y virus como indicadores de riesgo a la salud pública: estos son dos de los temas a discutirse en la entrevista de hoy con Erin Symonds, una estudiante doctoral de la Universidad de Sur de la Florida.
PROVIDENCE, R.I. [Brown University] -- A new study provides evidence from lab experiments that a drug already used in people to fight tapeworms might also prove effective against strains of the superbug MRSA, which kills thousands of people a year in the United States. 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....

When scientists launch a spacecraft into space, they're also launching thousands of bacteria along with it.

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
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

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
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 multidrug-resistant, incredibly contagious Shigella has popped up in 32 US states in the past year. The bacteria infect your intestines and trigger crampy rectal pain, bloody or mucus-laced diarrhea and vomiting. What can you do? Vigilant hygiene. And if you do get sick, go for an over-the-c...

Bovine viral diarrhea virus infections result in one of the most costly diseases among cattle with losses in U.S. herds estimated at $2 billion per year, according to professor Christopher Chase of the South Dakota State University Veterinary and Biomedical Sciences Department.

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
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
Many different microbes can cause pneumonia, and treatment may be delayed or off target if doctors cannot tell which bug is the culprit. A novel approach—analyzing a patient's breath for key chemical compounds made by the infecting microbe—may help detect invasive aspergillosis, a fungal infecti... Read More
A University of Colorado Boulder and North Carolina State University-led team has produced the first atlas of airborne microbes across the continental U.S., a feat that has implications for better understanding health and disease in humans, animals and crops. 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 ...

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
