Airborne prions are also infectious and can induce mad cow disease or Creutzfeldt-Jakob disorder. This is the surprising conclusion of researchers at the University of Zurich, the University Hospital Zurich and the University of Tbingen. They recommend precautionary measures for scientific labs, slaughterhouses and animal feed plants. The prion is the infectious agent that caused the epidemic of mad cow disease, also termed bovine spongiform encephalopathy (BSE), and claimed the life of over...

Scientists at the University of Zurich (Switzerland) and the Federal Research Institute for Animal Health (FLI; Tuebingen) have challenged the notion that airborne prions are innocuous. Details of how inhalation of prion-tainted aerosols induced disease are published January 13 in the open-access journal PLoS Pathogens. It is known that prions can be transmitted through contaminated surgical instruments and, more rarely, through blood transfusions. However, prions are not generally considered...

Findings Point to Normal Prion Protein as Most Effective Therapeutic Target for "Mad Cow" and Related Diseases Scientists from the Florida campus of The Scripps Research Institute have shown that prions, bits of infectious protein that can cause fatal neurodegenerative disease such as bovine spongiform encephalopathy (BSE) or "mad cow disease," have the ability to adapt to survive in a new host environment. In this regard, although they lack DNA and RNA, they behave much like viruses,...

About one in six Americans, or roughly 48 million people, are sickened from with foodborne illnesses each year, according to new estimates released Wednesday from the U.S. Centers for Disease Control and Prevention (CDC). Of those, nearly 3,000 are killed and 128,000 require hospitalization due to their illness, the health agency said. The figures are the first comprehensive estimates since 1999, and are the CDC's first to include illnesses caused solely by foods consumed in the United...

Habitat destruction and species extinction may lead to an increase in diseases that infect humans and other species, according to a paper in the journal Nature co-authored by a University of Florida ecologist. In the paper to be published Thursday, UF biology professor Robert D. Holt and his colleagues reported that by reviewing studies from a wide range of systems, including data from plants, animals and bacteria, they were able to relate dimensions of environmental loss, and in particular...

A new study tracking the DNA signature of the plague has found that the deadly disease first broke out in China more than 2,600 years ago before making its way to Europe via Central Asia's "Silk Road" trade route. The findings prove many suspicions about the long-believed Chinese origins of the plague, which killed nearly a third of Europeans during the Middle Ages. Scientists from around the world sequenced 17 strains of Y. pestis, connecting them as pathogens that mutated from a common...

Finding may also lead to new treatments for measles, mumps and influenza Scientists at Weill Cornell Medical College have identified a potential new treatment for the Nipah and Hendra viruses, two lethal and emerging viruses for which there is currently no treatment or vaccine available. The approach could also lead to new therapies for measles, mumps and the flu. The new research appears in today's edition of the prestigious journal Public Library of Science (PLoS) Pathogens. The Nipah and...

Scientists to research connections between infectious diseases and land use, global warming and other environmental changes To better understand the ecological mechanisms that govern relationships between human-induced environmental changes and the emergence and transmission of infectious diseases, the National Science Foundation (NSF) and National Institutes of Health (NIH) have awarded 10 grants through the Ecology of Infectious Diseases (EID) program. It is the 11th year of funding in the...

Black Death, one of the deadliest pandemics in human history, has been confirmed by anthropologists to have been caused by a germ called Yersinia pestis. Researchers studied tooth and bone samples from 76 skeletons discovered in "plague pits" in France, Germany, Italy and the Netherlands and found DNA evidence that Y. pestis was to blame for the plague that wiped out nearly a third of Europe's population during the Middle Ages. It was believed for more than a century that Y. pestis was the...

Kathleen Alexander, associate professor of wildlife in Virginia Tech's College of Natural Resources and Environment, has discovered a novel tuberculosis (TB) species in the Mycobacterium tuberculosis complex, a group of pathogens that have adapted by using mammals as hosts. It has been nearly two decades since a new organism was identified in this group; the majority were discovered in the early and mid 20th century. Tuberculosis is presently the leading cause of death from infectious...
