Manmade climate change is the main driver behind the unexpected emergence of a group of bacteria in northern Europe which can cause gastroenteritis, new research by a group of international experts shows.

The paper, published in the journal Nature Climate Change on Sunday, provided some of th... Read More

After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... 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

Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?

The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... 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 toward... Read More

Mothers with IgG antibodies to Toxoplasma gondii at delivery are at risk for later self-harm or suicide, particularly if they have higher titers against the parasite, a Danish study found.

The risk of self-directed violent behavior was increased 1.53-fold (95% CI 1.27 to 1.85, Psk rose to 1.9... Read More

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

Just a quick note to say how much I enjoy TWiM, and in particular, how much I enjoyed episode 32 featuring Rosie Redfield. I don't know how you find time to do this, but I'm gl... Read More

The HPV vaccine not only has resulted in a decrease in human papillomavirus infection in immunized teens but also in teens who were not immunized.

The study is believed to be the first to show a substantial decrease in HPV infection in a community setting as well as herd protection -- a decre... Read More

Bacterial genomes differ dramatically in size: from 140Kb to 13Mb (those numbers might be off now...please let me know if something has broken the record. Yes, I know the lower estimate can change based on semantics, but there are a bunch in that range). Although we have some clues as to how sel... Read More

In the search for new life, scientists have studied the depths of the ocean and the lips of steaming volcanoes. They've looked on Mars and the moons of Jupiter, and even planets beyond this solar system.

Dr. David Relman went searching inside his own mouth. On a routine dental visit in 1998, ... Read More

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

The new research assessed the association between bacterial... Read More

Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More

A third of the world’s human population is infected with a dormant tuberculosis bacteria, primarily people living in developing countries. The bacteria presents a lifelong TB risk. Recent research out of the University of Copenhagen demonstrates that the risk of tuberculosis breaking out is four... Read More

One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), ... Read More

One year on from Europe’s worst recorded outbreak of Escherichia coli infection, governments have made little progress towards improving the monitoring and reporting systems that allowed the crisis to drag on for weeks. The disease, which was spread by contaminated fenugreek sprouts, swept acros... Read More

Cholera is an extremely virulent intestinal infection caused by ingestion of the bacterium Vibrio cholerae (V. cholerae). EU researchers elucidated the molecular mechanisms behind expression of virulence genes with important implications for new therapies.

The second of two papers on avian influenza H5N1 virus that caused such a furor in the past year was published today in the journal Science. I have carefully read the paper by Fouchier and colleagues, and I assure you that it does not enable the production of a deadly biological weapon. The resu... Read More

India has been free of polio for over one year. This is a remarkable accomplishment, considering that just 30 years ago the country recorded 200,000 cases of the disease annually, or one every three minutes. With polio endemic in two neighboring countries, Pakistan and Afghanistan, and in the mo... Read More
