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.
Let's face it: colonoscopies are pretty unpleasant. But what if you could eat a spoonful of yogurt to check for cancer rather than enduring that procedure? MIT professor Sangeeta Bhatia is working on engineered bacteria that detects colorectal cancer. Read More

Now about the term Talmudic.
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.

Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.
The study found that greater n... Read More
Fecal transplants can be life-saving for people with stubborn bacterial infections, but they're not for the faint of heart. So doctors have come up with a way to make them more palatable – the frozen poop pill.
People infected with Clostridium difficile suffer debilitating diarrhea, but the b... Read More
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
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
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
When scientists launch a spacecraft into space, they're also launching thousands of bacteria along with it.

To prepare the Curiosity rover for its trip to Mars, NASA scrubbed it with alcohol and baked it at... 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....

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
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
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
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
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
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.
