In regard to your question as to cases of known alteration of host behavior by virus that increases the rate of contact among hosts (Twiv 70), the most dramatic example is given by rabies. This extraordinary virus can convert a neurologically and behaviorally... Read More
On episode #77 of the podcast This Week in Virology, Vincent, Alan, and Rich revisit circovirus contamination of Rotarix, then discuss poxvirus-like replication of mimivirus in the cell cytoplasm, and whether... Read More
The contamination of the rotavirus vaccine Rotarix with porcine circovirus 1 DNA was revealed by deep sequencing. The same technique was also used to demonstrate that oral poliovirus vaccine does not contain viruses that can cause poliomyelitis. Read More
A brewing trick could enable cask ales, unfiltered and unpasteurized beer, to be served on trains, aircraft and cruise ships. While ale normally takes two days to settle after each jolt, British brewer Marston's has developed a cask beer that can be poured a minute after the barrel has been move... Read More

The U.S. Department of Agriculture recommends not washing raw poultry, beef, pork, lamb, or veal before cooking it. Chicken, too.
Bacteria in raw meat and poultry juices can be spread to other foods, utensils, and surfaces, the USDA says in its fact sheet "Washing Food: Do... Read More
Scientists are learning how our immune system senses and tracks down infection in the body by responding to chemical "scents" emitted by bacteria. Studying how immune cells manipulate their movement in response to external signals could shed light not only on how our immune system functions but ... Read More
Researchers are finding clever ways to explore nanotechnology for medical therapies. In a study published Thursday in the journal Immunity, researchers used a "nanovaccine" to reverse diabetes in mice with the disease.
Nanoparticles are spheres that are thousands of times smaller than any typ... Read More

A University of Alberta-led research team has discovered an influenza detector gene that could potentially prevent the transmission of the virus to humans.
Katharine Magor, a U of A associate professor of biology, has identified the genetic detector that allows ducks to live, unharmed, as the... Read More
Scientists have found proteins in egg whites that could be used to fight infections which cost the chicken industry billions of pounds each year.
Researchers from The Roslin Institute, at The University of Edinburgh, have discovered that these recently-identified proteins have properties that... Read More
The human body's immune system can quickly track down and kill cells that don't belong. Take certain kinds of bacteria: molecules on their surfaces flag them as foreign invaders, alerting the body's defenders to the breach and drawing a full-fledged attack on anything waving that molecular flag....
