Immunizing calves with either of two forms of a vaccine newly developed by Agricultural Research Service (ARS) scientists might reduce the spread of sometimes deadly Escherichia coli O157:H7 bacteria. The microbe can flourish in the animals' digestive tracts, yet doesn't cause them to show clini... Read More
New research reveals a mutation on a gene that makes children susceptible to a severe form of mycobacterial disease. The work not only supports a controversial idea that certain genes evolved to combat specific bacteria but also reveals new mechanistic details of how the immune system fights off... Read More
On episode #63 of the podcast This Week in Virology, Vincent, Alan, and Rich talk about US government contract for freeze-dried smallpox vaccine, red squirrels in the UK threatened by poxvirus, and ... Read More
On December 10, 2009, the American Veterinary Medical Association (AVMA) announced the death of another pet from the 2009 H1N1 influenza virus. This brings the national total of pet deaths associated with the virus to 11 pets – seven cats and four ferrets. The first US case of a pet dying from t... Read More
The World Health Organization on Tuesday began using a new and more effective polio vaccine to eradicate the crippling virus in parts of Afghanistan.
Although most of Afghanistan is belived to be polio free, the disease has gone unchecked in 13 districts where security is a major concern.

The Roseobacter clade represents one of the most abundant, metabolically versatile and ecologically important bacterial groups found in marine habitats. A detailed molecular investigation of the regulatory and metabolic networks of these organisms is currently limited for many strains by missing... Read More
Recently, while reviewing some documents, I found a Los Angeles Health Department 2005 ACDC Special Report captioned "Please Pass The Bacteria: An Outbreak of Clostridium Perfringens Associated With Catered Thanksgiving Meals". I liked the title, and thought I would explore the subject of food... Read More
The possibility of finding a successful HIV vaccine will require a new and comprehensive strategy, Aids researchers have said. Promising vaccine trials, the most recent having been conducted in Thailand was found to reduce HIV/Aids transmission by about 30 per cent only.
Dr Pontiano Kaleebu, ... Read More
Researchers at Binghamton University, State University of New York, have identified three key regulators required for the formation and development of biofilms. The discovery could lead to new ways of treating chronic infections.

A rabies-based vaccine protects monkeys against SIV, the simian equivalent of HIV, a finding that may help in efforts to develop an AIDS vaccine, say U.S. researchers.
The team from Thomas Jefferson University in Philadelphia used highly attenuated rabies virus vaccine vectors to protect monk... Read More
According to an August report by the President’s Council of Advisors on Science and Technology, a fall resurgence of the H1N1 virus could “cause between 30,000 and 90,000 deaths in the U.S., concentrated among children and young adults.”
More than half of 36 children who died from the H1N1 vi... Read More
Researchers in Germany have identified a new antimicrobial peptide that demonstrates significant activity against a variety of bacteria, including multiresistant human strains such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). The discovery was... Read More
Humans in solitary confinement can go crazy, talking to themselves and trying to break free. Now scientists from New Mexico and New Hampshire are reporting that bacteria locked in solitary confinement know they are locked up, talk to themselves, and try to break free of their imprisonment.

In some ways a cell in your body or an organelle in that cell is like an ancient walled town. Life inside either depends critically on the intelligence of the gatekeepers.
If too many barbarians sneak into town, the town may be put to the torch. And if the cellular gatekeepers can't control t... Read More
A new report finds that the Centers for Disease Control and Prevention did a poor job of screening medical experts for financial conflicts when it hired them to advise the agency on vaccine safety, officials said Thursday.
Most of the experts who served on advisory panels in 2007 to evaluate... Read More

If the Viking labeled-release experiment on Mars in 1976 had tested glucose optical isomers separately, it might have avoided lingering doubts about its apparently positive results suggesting biological activity, say microbiologist Henry J. Sun of the Desert Research Institute in Las Vegas, Nev.... Read More
In the summer of 1989, two papers about viruses were published in high-profile journals. One described the engineering of a recombinant poliovirus bearing on its surface an antigen from HIV-1. The second paper claimed that transgenic mice could be made by adding DNA to sperm before using them to... Read More
Beetles whose flashes punctuate summer skies; killer fish that lure prey with an enticing light; algae that rat out their attackers with a telltale glow. These ominous organisms might seem like creatures from out of this world, but thanks to some clever chemistry, such beings are in fact abundan... Read More
Imagine you were trapped in a room for weeks with nothing to eat but a single leaf of lettuce. Sound like a nightmare in crash dieting?
For microscopic bacteria holed up in ancient buried salt flats in California's Death Valley, that's life. In fact, according to a new study, the fasting bugs... Read More
