HIV-positive women who are breastfeeding should not be given vitamin A supplements because it increases the risk of transmitting the AIDS virus to their infants, researchers said Thursday. Mother-to-child transmission of HIV has been largely controlled in the United States and other developed co... Read More
South Dakota State University research is exploring a "fusion strategy" for making improved vaccines to protect pigs and humans against some strains of E. coli.
The SDSU researchers altered the toxins produced by a form of E. coli and genetically fused the non-poisonous "toxoid" to a protein... Read More
Water, water everywhere, but in the developing world or in areas ravaged by natural disasters – like the ongoing flooding in Pakistan, for instance – there’s often not a clean, purified drop to be found. Water is usually made potable in such places via filters that physically trap bacteria as wa... Read More
How did bacteria spread through two Iowa egg farms, leading to the largest Salmonella enteritidis outbreak ever recorded in the U.S.? Take your pick. Stomach-turning inspection reports released Monday by the Food and Drug Administration found wild birds, which can carry the disease, flying and... Read More
We tend to think of bacteria as engaging in chemical warfare only when they attack us, wreaking havoc on our cells. But the microbiome is a vicious place, with many species hurling toxins at each other, attempting to gain a competitive advantage. A bacterium called Bacillus subtilis goes beyond... Read More
Infrared spectroscopy can detect E. coli faster than current testing methods, and can cut days off investigations of outbreaks, according to a study at Purdue University.
Lisa Mauer, an associate professor of food science, detected E. coli in ground beef in one hour using Fourier transform in... Read More
Scientists from the National Institutes of Health and University of Chicago have found a promising treatment method that in laboratory mice reduces the severity of skin and soft-tissue damage caused by USA300, the leading cause of community-associated Staphylococcus aureus infections in the Unit...

Group A Streptococcus (GAS) is responsible for infections ranging from “strep throat” to necrotizing fasciitis, aka the “flesh-eating disease”, a severe and invasive condition that has seen a marked increase in incidence in the past 30 years. The increase has been pinned on a single clone of th... Read More
You can "check in" to restaurants and bars, so how about health clinics while you get tested for sexually transmitted diseases?
Foursquare, the online application people use to tell their friends and strangers where they are, is offering a special virtual "badge" through September to people w... Read More
Blood hounds, cadaver dogs, and other canines who serve humanity may soon have a new partner ― disease detector dogs ― thanks to an unusual experiment in which scientists trained mice to identify feces of ducks infected with bird influenza. Migrating ducks, geese, and other birds can carry and s... Read More
Milk is well known as a great dietary source of protein and calcium, not to mention an indispensable companion to cookies. But "nature's perfect food," a label given to milk over time by a variety of boosters, including consumer activists, government nutritionists and the American Dairy Council... Read More
Howard Goldfine, Professor of Microbiology at the University of Pennsylvania School of Medicine, has authored a new post on Small Things Considered that looks at the interesting evolution of plasmalogens from anaerobes to plant and animal cells.
"Plasmalogens appeared early, but did not survi... Read More
A federal appeals court on Friday upheld a ruling that vaccines are not to blame for autism.
The U.S. Court of Appeals for the Federal Circuit upheld a decision last year by a special vaccine court, which concluded there's little if any evidence to support claims of a vaccine-autism link.

Using beams of light for diagnosis and monitoring disease may sound like something out of science fiction.
But scientists at the Massachusetts Institute of Technology are trying to use light so people with Type I diabetes can test their blood sugar levels with light, instead of with a needle,... Read More
A wide range of antibiotics given to dairy cows routinely end up on the ground and in manure lagoons, but are mostly broken down before they reach groundwater, according to a new study.
The findings should help alleviate longstanding fears that dairy farms, and the fields fertilized with thei... Read More
The world’s victory over smallpox has had an unfortunate consequence: monkeypox cases are surging in tropical Africa.
The disease is related to smallpox, though usually less serious, although in rare cases, it too can kill, blind or scar victims. Also, it is much less likely to jump between p... Read More
Under a magnification of 2500X, this colorized scanning electron micrograph (SEM) revealed the presence of a large number of Gram-negative Salmonella typhimurium bacteria that had been isolated from a pure culture. See PHIL 10984 for a black and white version of this image. Read More
A unique experiment at Rice University that forces bacteria into a head-to-head competition for evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level. An exacting new analysis of the experiment has revealed precisely how specific genet... Read More
Smelly feet may be the price we have to pay for saving the planet. A new study reported by New Scientist has discovered that nanoparticles commonly found in antibacterial socks may be inadvertently raising levels of greenhouse gases.
Researchers are concerned that silver nanoparticles - anti... Read More
