New understanding of how bacteria build their protective cell wall solves persistent puzzler.
Using a series of chemical and genetic tricks to interrogate a dizzying cast of characters involved in the process of building a cell wall, researchers believe they have discovered the hidden identit... Read More
Paul Duprex joins the TWiV team to discuss the current moratorium on viral research to alter transmission, range and resistance, infectivity and immunity, and pathogenesis.
The Ebola outbreak continues to roil West Africa, with the World Health Organization announcing Thursday that the death toll has climbed to 729 in Guinea, Sierra Leone and Liberia. More than 1,300 people are infected.
To help limit the spread of the disease the U.S. Centers for Disease Contro... Read More
Rapid detection of antibiotic resistance is vital in assessing the appropriate antibiotic therapy for an infection. Participants will present data on two new inex... Read More
The presence of lactic acid bacteria in intestinal flora is important for the healthy development of the immune system in children's early years. Now, a Danish study that tracked over 300 children in their first 3 years of life, found that longer breastfeeding encouraged lactic acid bacteria to ... Read More
For the first time, doctors have used DNA-sequencing technology to diagnose and treat a boy in an emergency. It's a big step for DNA sequencing—that the technology is able to work so quickly, and to help a patient directly. As useful as DNA sequencing is for research and genetic counseling, befo...

Since the 1950s farmers have fed antibiotic growth promoters (AGPs) to livestock. Overusing these substances can create superbugs, pathogens that are resistant to multiple drugs and could be passed along to humans. Mindful of that, companies such as Perdue Farms have stopped using the drugs to m... Read More
Extramural basic research at the Mount Sinai School of Medicine, funded by the U.S. Army Research Laboratory – Army Research Office (ARL-ARO), has led to discoveries of the biochemical mechanisms for viral growth and of an unprecedented method that may inhibit viral replication. These fundamenta... Read More
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
In the photo series "Impermanence," South Korean artist Seung-Hwan Oh creates colorful, otherworldly portraits with a little help from some "friends" — emulsion-consuming microbes, that is.
By immersing an exposed roll of medium-format positive film in water containing these bacteria and lea... Read More
In this blog post, I discuss our Summer Research Program's "Lab Themed Dessert" competion, for which one of my students created a cake "sculpture" of Bdellovibrio attacking and invading E. coli. It was tasty, informative, and fun! My student clearly thought about Bdellovibrio a LOT during the ... Read More
A debilitating, mosquito-borne virus called chikungunya has made its way to North Carolina, health officials say. It's the state's first reported case of the virus.
The patient was likely infected in the Caribbean, according to the Forsyth County Department of Public Health. Chikungunya is prim... Read More
The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
Over the past few decades there appears to have been a never-ending stream of emerging diseases from AIDS to SARS and now MERS. Predictions are that global warming will bring... Read More
Last week two American aid workers who had contracted Ebola while working in west Africa were released from a U.S. hospital and pronounced “recovered.” They had been flown to Emory University Hospital in Atlanta from Liberia earlier this month to receive care in the hospital’s specialized infect...

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
HIV-1, the most common type of the virus that causes AIDS, has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of researchers has designed a way to snip o... Read More
Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.
An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More
A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to pr...
