This episode: Probiotics could help prevent folate deficiency!
The human microbiome consists of thousands of viral and microbial species which inhabit the human body and have co-evolved with us to protect against pathogens, regulate organ function and supply nutrients and other factors essential for health. When these members fall out of balance, it can le... Read More
Mathematics and Biology have a long history together. It goes back to early studies on epidemiology (such as John Snow‘s on cholera and the Broad Street pump), and includes Ross’s quantitative studies that show how malaria can be controlled by careful analysis of data. And, of course, there are ... Read More
Hello Vincent and Team TWIV,
I love Virology, and it is with much chagrin that I admit I have only recently started listening to TWIV. However I have tried to mend the error of my ways by: 1) proselytizing the benefits (keeping up-to-date with and... Read More
Infectious-disease doctors have proposed a speedier, easier approval process for drug companies developing antibiotics against untreatable illnesses.
The Infectious Diseases Society of America (IDSA) made the proposal today at a hearing of a subcommittee of the US House of Representatives Com... Read More
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... Read More
Living in the guts of worms are seemingly innocuous bacteria that contribute to their survival. With a flip of a switch, however, these same bacteria transform from harmless microbes into deadly insecticides.
In the current issue of Science, Michigan State University researchers led a study t... Read More
For a century, doctors have waged war against bacteria, using antibiotics as their weapons. But that relationship is changing as scientists become more familiar with the 100 trillion microbes that call us home — collectively known as the microbiome.
“I would like to lose the language of warfa... Read More
Children younger than 10 likely will be the most susceptible if a variant of the influenza A (H3N2) virus -- dubbed A (H3N2)v -- develops the ability to transmit easily among humans, researchers found.
Since August 2011, there have been 12 cases of infection with the variant -- which contains... Read More
Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.
The scientists and other experts said the work was a giant step towar... Read More
Members of a U.S. government biosecurity advisory board are offering a range of reactions to the news that they are being asked to take a second look at two controversial flu studies. Some have not previously spoken publicly about the issue, which has sparked a global debate about biosecurity ve... Read More
Treatment with lopinavir/ritonavir (Kaletra) reduced the risk that HIV-infected children would become co-infected with malaria, researchers said here.
Compared with treatment based on non-nucleoside reverse transcriptase inhibitors (NNRTIs), therapy with the protease inhibitor-based combinati... Read More
Signals from natural intestinal bacteria are necessary for an effective immune response to various viral or bacterial germs. This was the result of experiments by a research team led by Prof. Dr. Andreas Diefenbach and Stephanie Ganal at the Institute of Medical Microbiology and Hygiene of the F... Read More
Bloodstream infections caused by the MRSA superbug may be on the decline in communities across the U.S., according to a large study of military personnel.
Previous data from the Centers for Disease Control and Prevention show a drop in infections contracted in healthcare settings. But the tra... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More

Understanding what happens to a soybean root hair system infected by symbiotic, nitrogen-fixing soil bacteria, Bradyrhizobium japonicum, could go a long way toward using this symbiosis to redesign plants and improve crop yields, benefitting both food and biofuel production. Because of their exte... Read More
Ron Fouchier has discussed his influenza H5N1 transmission experiments in ferrets at an ASM Biodefense Conference, clarifying several assumptions about the transmissibility of the virus in this animal model. Read More
Nearly four months ago I stood at the front of a crowded classroom at Columbia University and began teaching the third year of my undergraduate virology course. Twice a week we discussed the basic principles of virology, including how virions are built, how they replicate, and how they cause dis... Read More
Mak Saito, a biogeochemist at Woods Hole Oceanographic Institution, has been selected for a Marine Microbiology Initiative (MMI) investigator award by the Gordon and Betty Moore Foundation. Saito is one of 16 scientists from 14 different institutions who will receive funds from a total of up to ... Read More
