Researchers suspect H7N9 virus is in bird markets as human cases rise rapidly. Virologists know its name: H7N9. What they don’t yet know is whether this novel avian influenza virus — first reported in humans in China less than two weeks ago — will rapidly fizzle out, become established in animal... Read More
The Gulf of Mexico may have a much greater natural ability to self-clean oil spills than previously believed, an expert in bioremediation said here today at the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society.

Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, in a special topic issue focused ...

In the most extensive screen of its kind, Texas Biomed scientists have demonstrated the feasibility of repurposing already-approved drugs for use against highly pathogenic bacteria and viruses. The pathogens included emerging diseases and potential bioterror threats ranging from anthrax to the M... Read More
Taking an approach similar to that used for discovering new therapeutic drugs, chemists at the University of California, Davis, have found several compounds that can boost oil production by green microscopic algae, a potential source of biodiesel and other "green" fuels. The work appears online ... Read More
The research has created the first detailed and up-to-date map of dengue distribution worldwide, enabling researchers to estimate the total numbers of people affected by the virus globally, regionally and nationally. The findings will help to guide efforts in vaccine, drug and vector control str... Read More

When it comes to the evolution of life on earth, those who have been here longest have seniority. And after four billion years, bacteria reign supreme. Unfortunately for us, some of them have been using that time to ... Read More
Like humans, mice can become infected with Borrelia. However, not all mice that come into contact with these bacteria contract the dreaded Lyme disease: Animals with a particular gene variant are immune to the bacteria, as scientists from the universities of Zurich and Lund demonstrate. Wild mic... Read More
U.S. Department of Agriculture (USDA) scientists have found an effective method to infect house flies with a virus that stops the flies from reproducing.
House flies can transmit hundreds of animal and human pathogens like Salmonella, Escherichia coli and Shigella bacteria, which cause foodbo... Read More
Microbes turn nutrient in beef into an artery-clogging menace. Lean steak is low in fat and cholesterol and high in protein — qualities normally considered healthy. But eating a lot of it can still cause heart disease. Researchers have now laid the blame on bacteria in the human gut that convert... Read More
Few people check into a hospital expecting to come down with a severe case of diarrhea while undergoing care for an entirely unrelated problem. And even fewer expect to die of the hospital-acquired intestinal infection that causes the watery stools. Yet for approximately 14,000 Americans each ye... Read More
In a recent study published in PNAS, Houry and collaborators used time-lapse microscopy to monitor the biofilms formed by the bacterium Bacillus thuringiensis and noted that a small subset (0.1 to 1%) of all the cells in the biofilm were motile. The rest of the cells were sessile and immobile ex... Read More
Without the awesome power of microbes, these wonders of the ancient world would never have been built! Everyone knows about the awesome number of stone blocks and huge manpower requirements, but few know the important role that yeast had to play in building the pyramids. Read More
So far there have only been isolated cases of bird flu in humans, and no widespread transmission as the H5N1 virus can’t replicate efficiently in the nose. The new study, using weakened viruses in the lab, supports the conclusions of controversial research published in 2012 which demonstrated th... Read More

Chinese authorities slaughtered over 20,000 birds at a poultry market in Shanghai on Friday as the death toll from a new strain of bird flu mounted to six, spreading concern overseas and sparking a sell-off in airline shares in Europe and Hong Kong.
The local government in Shanghai said th... Read More
National Institutes of Health (NIH) researchers have developed a model of infection in rhesus macaques that will help scientists around the world better understand how an emerging coronavirus, first identified in September 2012, affects people. The virus has so far infected at least 17 people in... Read More
Thousands of women suffer from overactive bladder (OAB) or the sudden need to urinate, yet many don’t get relief from medication. Researchers at Loyola University Health System believe certain bacteria may be to blame.
Loyola has launched a clinical trial to determine if the bacteria present ... Read More
