Bacteriophages – the friendly viruses that can wreak havoc on harmful bacteria – are being harnessed to beat back Salmonella in livestock. A phage invented and recently patented by food safety researchers at Iowa State University is the first phage to control the spread of Salmonella in swine and to prevent the bacterium from developing into a vehicle of foodborne illness.
“The pen isn’t the only place pigs get Salmonella,” said D.L. (Hank) Harris, an animal science researcher at ISU. “They’ve got Salmonella when they come in from the farm. It turns out that vaccine and probiotics have not been very successful in reducing Salmonella in lairage immediately before slaughter. So we’re using pigs in an acute infection model to evaluate bacteriophage.”
Harris’ work to find effective ways to use bacteriophage in pigs has been successful enough to warrant further study in a collaborative Food Safety Consortium project later this year. Harris will team with Billy Hargis, an FSC researcher who directs the University of Arkansas Poultry Health Research Laboratory, to explore ways to maximize production of bacteriophages and to determine its effectiveness against various types of Salmonella.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
