    Imagine a low-cost treatment for a life-threatening infection that could cure up to 90 percent of patients with minimal side effects, often in a few days. It may sound like a miracle drug, but this cutting-edge treatment is profoundly simple—though somewhat icky: take the stool of healthy patients to cure those with hard-to-treat intestinal infections. A small but growing number of physicians have begun using these so-called fecal transplants to treat Clostridium difficile, commonly referred to as C-diff, a bacterial infection that causes nausea, cramping and diarrhea. The germ afflicts a half-million Americans annually and kills about 15,000 of them....

    Researchers for the first time created microbes containing artificial DNA, expanding the universal genetic code that guides life. The advance one day could lead to new antibiotics, vaccines and other medical products not possible with today's bioscience. In a report published Wednesday in Nature, the scientists said they created two additions to the normal genetic code, and then prompted bacteria to incorporate these pieces of man-made DNA with few ill effects. "The cells recognized it as natural," said chemical biologist Floyd Romesberg at the Scripps Research Institute in La Jolla, Calif., who led the research group.

    For over a century cranberries have been more than a Thanksgiving staple; they've also been heralded for their reported ability to prevent and even treat urinary tract infections.But clinical research attempting to link cranberry consumption to a reduction in urinary tract infections remains somewhat inconsistent. A 2012 study by a team from Taiwan and the U.S., published in the Archives of Internal Medicine, found that consuming cranberries did seem to prevent urinary tract infections in certain populations, but qualified the findings with a strong word of caution against using the "folk remedy" as a treatment.

    WASHINGTON, Aug. 14 (Xinhua) -- U.S. researchers said Wednesday they have discovered how a common oral bacterium can trigger a cascade of changes leading to colorectal cancer. The microorganism called fusobacteria, which are found in the mouth, may stimulate bad immune responses and turn on cancer growth genes to generate colorectal tumors, two studies published in the journal Cell Host & Microbe revealed. Colorectal cancer is the second leading cause of cancer-related death in the United States. Recent studies have shown that fusobacteria from the mouth are also abundant in tissues from colorectal cancer patients but it was not known...

    A 180-degree change in how doctors and hospital administrators think about germs is likely to almost eliminate the biggest risk of being hospitalized: getting an infection. Until now, doctors and hospital administrators routinely dismissed questions about cleanliness by saying "germs are everywhere." But at last week's meeting of the Society for Healthcare Epidemiologists of America in Atlanta, the focus was on making patients' rooms germ-free by testing for bacteria after cleaning and using ultra-violet light and room fogging machines. Finally, the medical community is acknowledging that inadequately cleaned rooms and equipment are to blame for infections and doing something about...

    NEW YORK (Reuters) - The logic behind weight-loss surgery seems simple: rearrange the digestive tract so the stomach can hold less food and the food bypasses part of the small intestine, allowing fewer of a meal's calories to be absorbed. Bye-bye, obesity.A study of lab mice, published on Wednesday, begs to differ. It concludes that one of the most common and effective forms of bariatric surgery, called Roux-en-Y gastric bypass, melts away pounds not - or not only - by re-routing the digestive tract, as long thought, but by changing the bacteria in the gut.Or, in non-scientific terms, the surgery...

    Astonishingly, a virus that exclusively attacks the cholera bacteria was caught having stolen the functional immune system of bacteria—and is even using it against its bacterial host. A study published this week in the journal Nature provides the first evidence that this type of virus, a bacteriophage (“phage” for short), can acquire a wholly functional and adaptive immune system, something that was thought to be a too complex task for the very basic and “dumb” virus. The phage used the stolen immune system to disable—and thus defeat—the cholera bacteria’s defense system against phages. Therefore, the phage can kill the cholera...

    Abstract: Recently, many jurisdictions have implemented bans or imposed taxes upon plastic grocery bags on environmental grounds. San Francisco County was the first major US jurisdiction to enact such a regulation, implementing a ban in 2007. There is evidence, however, that reusable grocery bags, a common substitute for plastic bags, contain potentially harmful bacteria. We examine emergency room admissions related to these bacteria in the wake of the San Francisco ban. We find that ER visits spiked when the ban went into effect. Relative to other counties, ER admissions increase by at least one fourth, and deaths exhibit a similar...

The agent reduces the growth of bacteria including E. coli, salmonella and listeria and could lead to sandwiches that stay fresh for more than a year, The (London) Sunday Times reported

    A Texas lake that turned blood-red this summer may not be a sign of the End Times, but probably is the end of a popular fishing and recreation spot. A drought has left the OC Fisher Reservoir in San Angelo State Park in West Texas almost entirely dry. The water that is left is stagnant, full of dead fish — and a deep, opaque red. The color has some apocalypse believers suggesting that OC Fisher is an early sign of the end of the world, but Texas Parks and Wildlife Inland Fisheries officials say the bloody look is the result...
  • Antibacterial stainless steel created

    Materials scientists at the University of Birmingham have devised a way of making stainless steel surfaces resistant to bacteria in a project funded by the Engineering and Physical Sciences Research Council which culminated this week. By introducing silver or copper into the steel surface (rather than coating it on to the surface), the researchers have developed a technique that not only kills bacteria but is very hard and resistant to wear and tear during cleaning. Bacteria resistant surfaces could be used in hospitals to prevent the spread of superbug infections on stainless steels surfaces, as well as in medical equipment,...

    Bacterial poisonAnthrax, septicemia and meningitis are some of the planet's most deadly infections. In part because doctors lack basic insights to prevent and cure diseases caused by so called Gram-positive bacteria. Now, a chemist from the University of Copenhagen has revealed the mechanism behind these deadly infections.By creating a synthetic version of a Gram-bacterial endotoxin, Danish synthetic chemist Christian Marcus Pedersen has made a contribution that'll compel immune biologists to revise their textbooks. More importantly, he has paved the first steps of the way towards new and effective types of antibiotics. Chemist in international collaboration with biologists and physiciansThe research...

    There may be no food more American than the burger. And according to meat lovers, there may be no health code regulation less American than North Carolina's rare and medium rare burger ban. From Winston-Salem to Nags Head, meat eaters are unable to order their burgers rare or even medium rare thanks to a state restriction that requires restaurants to cook ground beef to an internal temperature of 155 degrees Fahrenheit. That's enough heat to sufficiently kill dangerous bacteria like E. coli, according to state health officials. But it's also enough heat to kill all of the flavor, according to...

    Doctors have discovered that adding sugar to antibiotics increases their ability to knock out persistent staph infections (abstract). Certain types of bacteria called persisters shut down their metabolic processes when exposed to antibiotics. Adding sugar keeps the bacteria feeding, making them more susceptible to drugs. From the article: "Adding such a simple and widely available compound to existing antibiotics enhances their effectiveness against persisters, and fast. One test showed that a sugared up antibiotic could eliminate 99.9 percent of persisters in two hours, while a regular antibiotic did nothing. Doctors believe that this discovery will help treat urinary tract infections,...

    Hospital infections kill more Americans each year than AIDS, car accidents and breast cancer combined -- and researchers are searching for solutions. This week, a study of 153 Veterans Affairs hospitals shows that doing a simple swab test to identify and isolate the few patients carrying infection-causing bacteria can save lives. It's called screening, but even more important is cleaning. Studies are rolling in that hospitals need to be cleaner. In fact, if you're visiting a friend or relative in the hospital, don't bring flowers or candy -- take gloves and a canister of bleach wipes. Hospitals do an inadequate...

A study by the Translational Genomics Research Institute, found that Staphylococcus aureus – a bacteria that causes most staph infections including skin infections, pneumonia and blood poisoning – are present in meat and poultry from U.S. grocery stores at “unexpectedly high rates.”

    The joke that's going around is that the Mayans got it wrong: The world is ending this year, not 2012. Here's the lates sign of that. A superbug is spreading around America, and has hit Southern California. LA Times: A dangerous drug-resistant bacterium has spread to patients in Southern California, according to a study by Los Angeles County public health officials. More than 350 cases of the Carbapenem-Resistant Klebsiella pneumoniae, or CRKP, have been reported at healthcare facilities in Los Angeles County, mostly among elderly patients at skilled-nursing and long-term care facilities, according to a study by Dr. Dawn Terashita,...

    SAN FRANCISCO -- The seats of some well used methods of public transportation have been analyzed by a biologist and the results might keep commuters on their feet. A supervisor with San Francisco State University's biology lab recently tested the bacterial content of a random BART seat and a Muni seat. The Bay Citizen commissioned the study. On Muni's plastic seats she found two forms of harmless bacteria, and after using an alcohol wipe on the seat no bacteria was detected. But the cloth seats on BART told an entirely different story: tests of the seats on BART revealed fecal...

    No, no, no. No no no no no no no no. No, no. No. Fox News broke the story, which ought to make one immediately suspicious — it's not an organization noted for scientific acumen. But even worse, the paper claiming the discovery of bacteria fossils in carbonaceous chondrites was published in … the Journal of Cosmology. I've mentioned Cosmology before — it isn't a real science journal at all, but is the ginned-up website of a small group of crank academics obsessed with the idea of Hoyle and Wickramasinghe that life originated in outer space and simply rained down...
