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.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...
Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
