Rutgers researchers have discovered how HIV-1, the virus that causes AIDS, resists AZT, a drug widely used to treat AIDS.
The scientists, who report their findings in Nature Structural & Molecular Biology, believe their discovery helps researchers understand how important anti-AIDS treatments... Read More
Living in a crowded city doesn't sound like a recipe for good health, but it may have helped our ancestors protect their descendants from disease.
Some people carry a genetic sequence, or allele, that provides immunity to leprosy and tuberculosis. Mark Thomas, an evolutionary biologist from U... Read More
As cold and flu season approaches, we'll be hearing this: To stay healthy, be sure to wash your hands a lot. But to best prevent the spread of germs, you also need to dry your hands.
That point's driven home by a pair of studies published in the Journal of Applied Microbiology. The studies, q... Read More
Bacteria have developed a new way to resist a sweeping array of antibiotics, raising alarms about the spread of infections that might defy nearly all treatments.
Three Americans were recently diagnosed with the new infection, which they acquired during medical treatment in India and Pakistan.... Read More

An Oregon seafood company is recalling packaged crab meat products after testing revealed some products contained bacteria that could cause serious or fatal infections.
Hallmark Fisheries, based in Charleston, Oregon, is recalling crab meat sold under brand names Hallmark, Peacock, Quality Oc... Read More
Antibiotics can temporarily upset your stomach, but now it turns out that repeatedly taking them can trigger long-lasting changes in all those good germs that live in your gut, raising questions about lingering ill effects.
Nobody yet knows if that leads to later health problems. But the find... Read More
Researchers who observed hand washing in restrooms in major cities say 85% of adults are washing their hands after using public facilities, a new observational study shows.
The American Society for Microbiology (ASM) and the American Cleaning Institute (ACI) sent observers into restrooms in s... Read More
Using vancomycin before surgery appears to help reduce the risk of methicillin-resistant Staphylococcus aureus (MRSA) infection in patients testing positive for colonization with nasal swabs -- but may not help patients without preoperative colonization, researchers said here.
A retrospective... Read More
Balamuthia mandrillaris is a free-living ameba (a single-celled organism) found in soil and dust. Exposure to Balamuthia is likely to be common because of how widespread it is in the environment. However, very few cases of disease in humans have been found worldwide since Balamuthia was discove... Read More
People who go to countries like India seeking faster, cheaper medical care risk dire consequences to their own health and they also potentially put the general public at risk if they return home with antibiotic-resistant, emerging infections.That was the ominous message from experts last month...

Fidaxomicin is superior to vancomycin in treating recurrences of gastrointestinal Clostridium difficile infection, according to a blinded randomized trial presented here at the 50th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC).
"Over 20 years, vancomycin has been ... Read More
At the first sign of a disease pandemic, public health officials should begin strongly communicating about the extent of the outbreak and the steps that can be taken by the public to avoid infection, according to two mathematical biologists who have modified the most widely used infectious disea...

Spoilage bacteria that can cause red coloration of pickles' skin during fermentation may actually help clean up dyes in textile industry wastewater, according to a U.S. Department of Agriculture (USDA) study.
Some species of Lactobacilli-food-related microorganisms-can cause red coloring when... Read More
Scientists have successfully cloned a human virus offering new hope for the treatment of potentially life-threatening diseases.
Human cytomegalovirus (HCMV) is a major infectious cause of congenital malformations worldwide. The virus is also known to cause life-threatening disease in transpla... Read More
Bacteria and other microorganisms are known for their remarkable ability to become immune to nearly everything thrown at them, and now a new study provides us with some hints of how that's possible.
Short of being cast into the Sun, in Earth's inner core, or in the deepest corners of space, b... Read More
Whirling electron vortices could help materials scientists to map the properties of nanomaterials in new detail. A technique, detailed in the September 16 issue of Nature, could be used in electron microscopes as part of the continuing quest to scale down the size of electronic chips.
Optical... Read More
In a discovery that sheds new light on the history of AIDS, scientists have found evidence that the ancestor to the virus that causes the disease has been in monkeys and apes for at least 32,000 years — not just a few hundred years, as had been previously thought.
That means humans have pres... Read More
Bacteria that are able to survive every modern antibiotic are cropping up in many U.S. hospitals and are spreading outside the USA, public health officials say.
The bugs, reported by hospitals in more than 20 states, typically strike the critically ill and are fatal in 30% to 60% of cases. Is... Read More
Menachem Shoham, PhD, associate professor and researcher in the department of biochemistry at the Case Western Reserve University School of Medicine, has identified new anti-pathogenic drugs that, without killing the bacteria, render Methicillin Resistant Staphylococcus Aureus (MRSA) harmless by...
