Mad cow disease airborne
14 January 2011
Mad cow disease airborne
by Kate Melville
University of Zurich researchers have discovered that prions - the infectious proteins that can cause Creutzfeldt-Jakob (mad cow) disease - can be transmitted through the air. Creutzfeldt-Jakob disease is characterized by a progressive and invariably lethal breakdown of brain cells. The surprising finding will likely mean a whole new raft of precautionary measures for scientific labs, slaughterhouses and animal feed plants.
It was previously known that prions could be transmitted through contaminated surgical instruments and blood transfusions but prions were not generally considered to be airborne until now. Details of how inhalation of prion-tainted aerosols induced disease are published in the journal PLoS Pathogens.
In the new study, the researchers exposed mice to prion-containing aerosols which induced disease. Exposure to the aerosols for one minute was sufficient to induce disease in 100 percent of the mice. The researchers note that the longer the exposure, the shorter the incubation time in the recipient mice, after which they developed the clinical signs of a prion disease.
Interestingly, the prions appeared to transfer from the airways and colonize the brain directly, since various immune system defects - known from previous experiments to prevent the passage of prions from the gut to the brain - did not prevent infection.
The precautionary measures against prion infections have not typically included stringent protection against aerosols. Study leader Adriano Aguzzi recommends precautionary measures to minimize the risk of a prion infection in scientific laboratories, slaughterhouses and animal feed plants but he also emphasizes that the findings stem from laboratory conditions and that Creutzfeldt-Jakob patients do not exhale infectious prions.

NewsDaily: Swine flu survivors developed super flu antibodies
They said people who were infected in the H1N1 pandemic developed an unusual immune response, making antibodies that could protect them from all the seasonal H1N1 flu strains from the last decade, the deadly "Spanish flu" strain from 1918 and even a strain of the H5N1 avian flu.
"It says that a universal influenza vaccine is really possible," said Patrick Wilson of the University of Chicago, who worked on the paper published in the Journal of Experimental Medicine.
Many teams are working on a "universal" flu shot that could protect people from all flu strains for decades or even life.
U.S. officials say an effective universal flu vaccine would have enormous ramifications for the control of influenza, which kills anywhere from 3,300 to 49,000 people in the United States each year.
Wilson's team started making the antibodies in 2009 from nine people who had been infected in the first wave of the H1N1 swine flu pandemic before an H1N1 vaccine had been produced. The hope was to develop a way to protect healthcare personnel.
