Experimental malaria vaccine offers durable protection against many strains in NIH trial

An investigational malaria vaccine has protected a small number of healthy U.S. adults from infection with a malaria strain different from that contained in the vaccine, according to a study published today in the Proceedings of the National Academy of Sciences (PNAS). The National Institute of ... Read More

The New Science of Evolutionary Forecasting

German physicist Michael Lässig believes that soon it may be possible to make evolutionary forecasts. Scientists may not be able to predict what life will be like 100 million years from now, but they may be able to make short-term forecasts for the next few months or years. And if they’re making...

Kavli Microbiome Ideas Challenge - Researching Small Organisms with a Big Impact

All around you, life exists in microscopic communities — carpeting the insides (and outsides) of humans and animals, oceans, atmospheres, and ecosystems in between. Researchers have learned these microbes are ubiquitous and central to the makeup of most life on earth. But what scientists are sti... Read More

Major finding identifies nitrogen as key driver for gut health

Researchers from the University of Sydney have found that the availability of intestinal nitrogen to microbes in the gut plays a key role in regulating interactions between gut microbes and their host animal. The study is published today in Cell Metabolism and is led by researchers at the Univer... Read More

New vaccines againts zika can prevent neurological disorders in newborn mice

Two vaccines against Zika virus developed at the University of Pittsburgh School of Medicine have successfully conveyed immunity from female mice to pups conceived weeks after the mother's vaccination.

When challenged with Zika virus within a week of their birth, both vaccines protected the p... Read More

TWiV 439: The purloined envelope

Paul Bieniasz joins the TWiV team to talk about the co-option, millions of years ago, of an endogenous retrovirus envelope protein by hominid ancestors for host defense against viral infection.

A bacterial role in breast cancer development and prevention

Microbial infection is implicated in an ever-growing number of types of cancer. Adding to the already long list of microbial-associated cancers, an increasing body of evidence suggests breast cancer may also be associated with a specific microbial milieu. A report in Applied and Environmental Mi... Read More

Mount Sinai researchers track HIV in real time as it infects and spreads in living tissue

By watching brightly glowing HIV-infected immune cells move within mice, researchers at the Icahn School of Medicine at Mount Sinai have shown how infected immune cells latch onto an uninfected sister cell to directly transmit newly minted viral particles. These interactions allow HIV to spread ... Read More

Testing Begins On An Experimental Zika Vaccine With Inactivated Virus

Federal scientists have launched another test in human volunteers of a Zika vaccine. This one uses a more traditional approach than an experiment that started in August.

Federal officials are eager to develop a vaccine as quickly as possible, which is why they are pursuing multiple approaches... Read More

Infant's prolonged infection reveals mutation that helps bacteria tolerate antibiotics

A life-threatening infection in an infant with leukemia led to a St. Jude Children’s Research Hospital discovery of how prolonged infection sets the stage for bacterial persistence despite antibiotic susceptibility

NIH Scientists Develop New Mouse Model to Study Salmonella Meningitis

National Institutes of Health (NIH) scientists have established in mice a way to study potentially life-threatening meningitis caused by Salmonella. Bacterial meningitis happens when bacteria infect the central nervous system (CNS), causing a serious disease that can be life-threatening and diff... Read More

Colistin-Resistant Gene Detected in the U.S. for the Second Time: Investigators Alert to Its Possible Spread

Washington, DC - July 11, 2016 - For the second time, a clinical isolate of a bacterial pathogen has been detected in humans in the United States which carries the colistin resistance gene, mcr-1. This may also be the first case to show up in the US. That would be concerning because plasmids, g... Read More

Chlorhexidine use may select for colistin resistance

Infection control is a vital part of maintaining a safe healthcare facility, and the use of biocides and disinfectants to eliminate potential pathogens is an important part of infection control strategy. Pathogens can spread among patients via transfer to surfaces like doors, floors, and counter... Read More
