Toxoplasma gondii, an obligate intracellular parasite of the phylum Apicomplexa, has the unusual ability to infect virtually any warm-blooded animal. It is an extraordinarily successful parasite, infecting an estimated 30% of humans worldwide. The outcome of Toxoplasma infection is highly depend... Read More
In what could be a potential breakthrough in the battle against AIDS and a major development in the rational design of new drugs, scientists have engineered a new protein that prevents the virus from entering cells. This protein is based on a naturally occurring protein in the body that protects... Read More
New research suggests that infection with a probiotic strain of E. coli bacteria could help treat an reduce the negative effects of another E. coli infection that may be associated with Crohn's disease. Researchrs from the University of Auckland, New Zealand publish their results in the April 20... Read More
In episode 47 of MicrobeWorld Video, filmed at the American Association for the Advancement of Science Meeting in Washington, D.C., on February 20, 2011, Dr. Stan Maloy talks with the Editor of ProMED Mail, Read More
Viruses like human cytomegalovirus (HCMV) use your own cell machinery against you by hijacking your RNA polymerase machinery, among other things, to turn their genes into viral proteins. A study published in mBio this week reveals new information that could help in designing drugs to fend off th... Read More
"Hi, this is Dr. William Jarvis, President of Jason and Jarvis Associates and Medscape Infectious Diseases expert advisor. We've seen a continuation of the debate about whether active surveillance testing of patients for methicillin-resistant Staphylococcus aureus (MRSA) -- thereby identifying b... Read More
Dr.'s Racaniello and Despommier,

Researchers at The Johns Hopkins University School of Medicine have determined that electronic faucets are more likely to become contaminated with unacceptably high levels of bacteria, including Legionella spp., compared with traditional manually operated faucets. The study will be presented on... Read More
Organism's ability to distinguish strontium from calcium could help in dealing with nuclear waste. Common freshwater algae might hold a key to cleaning up after disasters such as Japan's Fukushima nuclear accident, scientists said yesterday at a meeting of the American Chemical Society in Anahei...

Health officials are investigating the deaths of nine patients at Alabama hospitals who were all given an intravenous nutritional supplement that investigators have found to have been contaminated by bacteria.
Ten other patients who received the nutritional supplement were also sickened by th... Read More
Antiviral drugs dispensed during the 2009 influenza pandemic generally failed to contain transmission. This poses the question of whether preparedness for a future pandemic should include plans to use antiviral drugs to mitigate transmission. The threat from avian influenza H1N5 prompted many co...

The prevalence of ticks infected with the Lyme disease–causing spirochete (Borrelia burgdorferi) is greater in areas with Japanese barberry than areas without. "Deer eat everything but barberry, and because they don’t eat barberry, they’re weeding out forests. They’re helping promote the invasiv... Read More
A nanotechnology-based biosensor being developed by Kansas State University researchers may allow early detection of both cancer cells and pathogens, leading to increased food safety and reduced health risks.
Lateef Syed, doctoral student in chemistry, Hyderabad, India, is developing the bios... Read More
Encapsulating antibiotics inside nanofibers, like a mummy inside a sarcophagus, gives them the amazing ability to destroy drug-resistant bacteria so completely that scientists described the remains as mere "ghosts," according to a report presented on March 29 at the the 241st National Meeting & ...

Reducing the ability of certain bacteria to fix carbon dioxide can greatly increase their production of hydrogen gas that can be used as a biofuel. Researchers from the University of Washington, Seattle, report their findings in the current issue of online journal mBio®.
"Hydrogen gas is a pr... Read More
Scientists today reported development of bacteria that serve as mobile pharmaceutical factories, both producing disease-fighting substances and delivering the potentially life-saving cargo to diseased areas of the body. They reported on this new candidate for treating diseases ranging from food ... Read More
