    DOES Louisiana hot sauce, a principal ingredient in the spicy New Orleans cocktail sauce commonly served with raw shellfish, kill certain bacteria found in raw oysters? The answer is yes, at least in the laboratory, researchers said in a preliminary report at a national scientific meeting on microbes and antibiotics yesterday. Principal ingredients of the traditional New Orleans cocktail sauce were found to kill a rare but sometimes fatal bacteria called Vibrio vulnificus. Dr. Sanders said that he saw his first case of V. vulnificus infection 10 years ago and that his interest in studying the sauces arose from lectures...

    The small intestine, where most vitamins and other micronutrients are digested and absorbed. Credit: Wikimedia Commons ______________________________________________________________________________________________________________________ Although the vast majority of research on the gut microbiome has focused on bacteria in the large intestine, a new study—one of a few to concentrate on microbes in the upper gastrointestinal tract—shows how the typical calorie-dense western diet can induce expansion of microbes that promote the digestion and absorption of high-fat foods. Several studies have shown that these bacteria can multiply within 24 to 48 hours in the small bowel in response to consumption of high-fat foods. The findings from this...

    You know you’ve made it when you’ve got a strain of Listeria named after you. “Listeria costaricensis” is the official name for a new bacteria identified by scientists from the Biotechnology Research Center at the Costa Rican Institute of Technology (TEC). According to a news release from TEC, the Costa Rican researchers, Johnny Peraza and Kattia Núńez, made the discovery in collaboration with scientists from the Pasteur Institute in Paris, France. Listeria is a group of bacteria composed of 18 species, two of which are pathogens, meaning that they cause serious harm to humans or animals that consume foods contaminated...
  • Woman dies after contracting flesh-eating bacteria from oysters

    Back in September, Texas residents Vicki Bergquist and wife Jeanette LeBlanc were visiting family in Louisiana. They went crabbing with friends and family on the coast, picking up a sack of raw oysters in a market in Westwego. It wasn't long after when LeBlanc's health rapidly declined, CBS affiliate KLFY-TV reports. The couple's friend Karen Bowers says she and LeBlanc shucked and ate about two dozen raw oysters. "About 36 hours later she started having extreme respiratory distress, had a rash on her legs and everything," Bergquist said. "An allergic reaction of sorts, that's what I would call it. That's...

    A North Korean soldier who defected to the South has been found to have anthrax antibodies in his bloodstream, local news reports. The unidentified soldier, believed to be the man who defected in November this year, would have been either exposed to or vaccinated against anthrax before he defected to South Korea. This comes after a report that North Korea is conducting biological weapons experiments to test the possibility of loading anthrax-laden warheads on its intercontinental ballistic missiles.
  • Alien life? Bacteria ‘that had not been there’ found on ISS hull, Russian cosmonaut says

    Living bacteria were found on the surface of the International Space Station (ISS), and they might have extraterrestrial origins, Russian cosmonaut Anton Shkaplerov said. The microorganisms will be studied further on Earth. Shkaplerov, an ISS expedition flight engineer who will take his third trip to the ISS in December as part of the Expedition 54 crew, said that scientists found living bacteria while they were taking samples from the surface of the station. Speaking to TASS, he said that the microorganisms might have come from outer space. ... However, traces of bacteria originating on Earth – from Madagascar – and...

    Yes, say some international experts citing the rise of the super bug. But experts in UAE disagree and argue for better prescription protocols and patient responsibilityThe case of the six-year-old girl who developed antibiotic resistance is not an isolated one in the world of antibiotics. As these super drugs are routinely prescribed, controversies on their abuse and overuse are beginning to throw a big question-mark on whether antibiotics have outgrown their effectiveness. The question doing the rounds in many medical corridors is: Is the golden age of antibiotics over? “No, this is not true,” said Dr Sandeep Pargi, consultant pulmonologist...

    After the E. coli samples arrive at the ISS, the experiment will examine how microgravity affects the bacteria's ability to thrive while exposed to antibiotics. Since humans started using antibiotics in the mid-20th century, pathogens like E. coli have evolved new genes that make them increasingly resistant to antibiotics. ... The NanoRacks CubeSat Deployer at the International Space Station will send the bacteria on their way, and the experiment will be conducted autonomously inside the cubesat.  Both naturally occurring and mutant strains of E. coli will be exposed to different concentrations of antibiotics. "The overall purpose of this is to...

    Cases have increased by 8% in just a week with nearly 2,000 people infected by the deadly airborne strain. Some 143 people have now been killed by the “medieval disease” in Madagascar. There are now warnings the plague could stretch across the sea and reach mainland Africa. Such an outbreak would be catastrophic and there are fears the virus could go global. Nine countries are now on high alert and have been told to brace for the plague.

    Bacterial cells treated with a common antibiotic have been spotted changing shape to survive while aboard the International Space Station (ISS). The way bacteria act in near-zero gravity environments could pose a serious problem for treating astronauts with infections. ... An experiment on the common E coli bacteria subjected it to different concentrations of the antibiotic gentamicin sulfate, a drug which kills the bug on Earth. However, in comparison to a control group on Earth, the space bacteria showed a 13-fold increase in cell numbers and a 73% reduction in cell column size.

    Our veterinarian told us that Leptospirosis (Lepto) is back in the area. He hasn't seen it in decades until a local dog died of it a couple of weeks ago. He gave our two slobber buckets a shot for it this morning and they'll be back for a booster in a month. He's very trustworthy about not prescribing more than is needed and was concerned about it. The bacteria grows in standing water so don't leave buckets or containers outside. We drained the fountain. Years ago, cattle would get it with water sitting in hoof prints on the ground. Hardly...

    An image and short film has been encoded in DNA, using the units of inheritance as a medium for storing information. Using a genome editing tool known as Crispr, US scientists inserted a gif - five frames of a horse galloping - into the DNA of bacteria. Then the team sequenced the bacterial DNA to retrieve the gif and the image, verifying that the microbes had indeed incorporated the data as intended. In order to insert this information into the genomes of bacteria, the researchers transferred the image and the movie onto nucleotides (building blocks of DNA), producing a code...

    Iced drinks from Starbucks and two other U.K. coffee chains contained "concerning" levels of fecal bacteria, according to a BBC investigation. [Snip] Tony Lewis, head of policy at the Chartered Institute of Environmental Health, said that the levels of bacteria found in the drinks were "concerning." He said the types of bacteria identified are "the source of human disease," adding that "These should not be present at any level, never mind the significant numbers found."

    Each year, more than 2 million people in the United States get antibiotic-resistant infections, according to the Centers for Disease Control and Prevention. At least 23,000 of them die. Unless breakthroughs are achieved, that toll will keep rising. If a new version of an antibiotic of last resort lives up to its promise, that date with doom may be averted. A study on this bolstered form of vancomycin by scientists at The Scripps Research Institute in La Jolla was released Monday. Researchers led by Dale Boger, co-chair of TSRI's Department of Chemistry, introduced three modifications to vancomycin, all lethal to...
  • SHOULD WE WORRY ABOUT ANCIENT PATHOGENS BEING REVIVED?

    Bacteria are some of the oldest and most diverse organisms on Earth. Apparently, they are also among the toughest; researchers in Mexico’s Cueva de los Cristales have isolated and cultured bacteria that have been trapped within the crystals for up to 50,000 years. These tiny creatures biding their time within a rock for millennia, but they are by no means the oldest bacteria ever isolated. Efforts have been underway for decades to isolate microorganisms from rock or other materials. One early attempt aimed to culture bacteria from within Permian (~289-252 mya) salt deposits. The study was beset by concerns about...

    Going into a hospital? It's getting riskier because of drug-resistant infections -- the kind almost no drug can cure. Despite one federal government "action plan" after another, the germs are winning. Government authorities are clueless about how many infections there are, or how many patients are dying. Alarming new research shows that one of the deadliest families of bugs, carbapenem-resistant Enterobacteriaceae, nicknamed CRE, may actually be striking three times more patients than the Centers for Disease Control and Prevention tells us. One lesson from the war against AIDS: Level with the public about the enormity of a problem if you...

    Meat contaminated with Listeria will not show signs of spoilage, such as sliminess or odor. You can't smell a food and tell it it is safe Listeria monocytogenes bacteria can cause a potentially fatal disease in people with vulnerable immune systems. Listeria infection is the third leading cause of death from food poisoning in the United States. About 1,600 people get sick from Listeria each year and about 260 die. 1 A number of food borne outbreaks in recent years have been attributed to Listeria. In 2016, a total of 358 frozen food products were recalled amid a Listeria outbreak...

    A new prediction says 2017 and 2018 will see major Lyme disease outbreaks in new areas. This could lead to lifelong health consequences, so where's the vaccine? Thanks to a changing climate it could be one of the worst on record: the ticks that carry the disease have been found in places where it has never before been a problem – and where most people don’t know how to respond. The danger zone isn’t confined to the US: similar signs are flagging potential outbreaks in Europe. Polish researchers predict a major outbreak there in 2018. In theory, Ostfeld’s early warning...
