Lifeline for 'Antibiotic of Last Resort': Mechanism That Triggers Resistance to Vancomycin Identified

A new study led by the scientific director of the Michael G. DeGroote Institute for Infectious Disease Research has uncovered for the first time how bacteria recognize and develop resistance to a powerful antibiotic used to treat superbug infections.

Gerry Wright, a professor in the Departmen... Read More

Cold fronts linked to European H5N1 outbreaks

Avian influenza (H5N1) outbreaks in Europe during the winter of 2005-2006 occurred at the edge of cold weather fronts, according to researchers from Princeton University and the Erasmus Medical Centre, Rotterdam, the Netherlands. Their results, published April 8 in the open-access journal PLoS P... Read More

Harnessing the Web and supercomputers to track pathogens as they evolve

Pathogens can now be easily tracked in time and space as they evolve, an advance that could revolutionize both public health and inform national security in the fight against infectious diseases. Developed by researchers that include scientists at the American Museum of Natural History, Supramap... Read More

Prevalence of HIV in Africa is leading to new strains of Salmonella

Scientists at the University of Liverpool have discovered that dangerous strains of Salmonella are beginning to emerge in people infected with HIV in Africa.

Their research has found that, in adults with HIV, new African Salmonellae can cause severe disease by invading cells in the blood and ... Read More

Medicine goes mobile: iPhone apps take vitals, track viruses

On tiny keypads and greasy touch screens, doctors, nurses, NPs and physicians assistants these days are doing a lot more than checking email and phone messages. Increasingly, health care workers are using their iPhones and other smart phones to track patient information, take vital statistics an... Read More

HIV invades through leaky cells: study

HIV infects women by weakening a cell barrier in the reproductive tract that normally keeps viruses out, Canadian researchers have discovered. HIV breaks down the tight bonds between epithelial cells, which usually form a protective layer that prevents viruses from infecting other cells.

Modified virus splits water

Massachusetts Institute of Technology (MIT) researchers have found a novel way to mimic the process by which plants use sunlight to split water into hydrogen and oxygen. They used a modified virus as a "biological scaffold" that can assemble the nanoscale components needed to split a water molec... Read More

Cellulosic Ethanol: Expanding Options, Identifying Obstacles

Agricultural Research Service (ARS) scientists are figuring out how to turn wheat straw into ethanol "gold," and learning more about the bacteria that can "infect" ethanol plants and interfere with fuel production.

At the ARS National Center for Agricultural Utilization Research (NCAUR) in Pe... Read More

UC study tests vaccine against bacteria

An experimental vaccine could be the newest weapon against a dangerous bacterial infection on the rise in hospitals and nursing homes around the United States.

Doctors at the University of Cincinnati and University Hospital are part of a national clinical trial testing a C. difficile - or C. ... Read More

TWiV 77

Wladimir writes:


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

TWiV 77: Non-nuclear proliferation



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

Poliovirus vaccine safety

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

New method of in-barrel fermentation allows for cask ale to be served on the go

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

Mid-stage trial notes efficacy in investigational hepatitis C treatment

Patients with chronic genotype 1 hepatitis C fared better when given an investigational drug developed by Johnson & Johnson division Tibotec and Vertex Pharmaceuticals than when given the standard therapy, after they had failed previous treatments, according to results of a mid-stage trial publi...

It’s Swine Flu’s Anniversary

It’s been exactly a year since the first diagnosed case of swine flu in San Francisco and six months since President Obama declared the pandemic a national emergency.

Last October, the city’s public health department administered 20,000 vaccines in a three-day period. Then, one day in January... Read More

Army: Broken procedures led to lab infection

An Army lab at Fort Detrick said Tuesday it did not follow proper procedures last November when a researcher infected herself with the tularemia bacteria.

The researcher at the U.S. Army Medical Research Institute of Infectious Diseases was exposed to the bacteria between Nov. 13 and 17, and ... Read More

Federal agency recommends not washing meat, chicken before you cook it

It's surprising.

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

How Immune Cells 'Sniff Out' Bacteria

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

A nanovaccine reverses diabetes in mice

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
