A team of researchers from Versailles Saint-Quentin-en-Yvelines University (UVSQ), Inserm and Pasteur Institute (Unité Mixte de Recherche 1181 Biostatistique, biomathématique, pharmacoépidémiologie et maladies infectieuses – B2PHI) has been able to provide for the first time an accurate estimate of both the incidence (annual number of new cases) and added direct cost of infections due to…
In a joint collaboration, researchers from Denmark and Switzerland have shown that bacteria produce a specific stress molecule, divide more slowly, and thus save energy when they are exposed to antibiotics. The new knowledge is expected to form the basis for development of a new type of antibiotics. All free-living organisms are under constant pressure to survive. Darwin dubbed this…
Antiseptic soap, mouthwash, and nose ointment after hospital discharge reduced infections and infection-associated hospitalizations due to MRSA in high-risk patients. Hospital patients who have methicillin-resistant Staphylococcus aureus (MRSA) can prevent future MRSA infections by following a standard bathing protocol after discharge. The Changing Lives by Eradicating Antibiotic Resistance, or…
A team of scientists led by researchers at the University of Georgia Center for Food Safety in Griffin has developed a machine-learning approach that could lead to quicker identification of the animal source of certain Salmonella outbreaks. In the research, published in Emerging Infectious Diseases, Xiangyu Deng and his colleagues used more than a thousand genomes to predict the animal sources,…
Researchers at the University of Waterloo have developed a new way to prevent and treat Chlamydia, the most common sexually transmitted bacterial infection in the world. The new treatment differs from the traditional antibiotic treatment as it is a type of gene therapy that is delivered via nanotechnology and is showing a 65 per cent success rate in preventing chlamydia infection on a single…
You’re sweating and feverish and have no idea why. Fortunately, Sandia National Laboratories scientists have built a device that can pinpoint what’s wrong in less than an hour. Unlike most medical diagnostic devices which can perform only one type of test — either protein or nucleic acid tests — Sandia’s SpinDx can now perform both. This allows it to identify nearly any cause of…
The holiday season just wouldn't be the same without delicious Christmas cookies. Impatience in the bakery, however, might be penalized with some unpleasant or even dangerous side-effects. Bruce Ruck, managing director of the New Jersey Poison Control Center at Rutgers University Medical School, talks about the risks associated with eating raw cookie dough: “It’s a potential recipe for food…
Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be replaced. Fraunhofer researchers can now apply a precisely matched drug directly to the replacement implant while significantly increasing the effectiveness of the antibiotic…
Researchers have developed laser-activated nanomaterials that integrate with wounded tissues to form seals that are superior to sutures for containing body fluids and preventing bacterial infection. Tissue repair following injury or during surgery is conventionally performed with sutures and staples, which can cause tissue damage and complications, including infection. Glues and adhesives have…
A deep neural network algorithm called BOTA uses bacterial genomes to identify unrecognized bacterial antigens.
Sepsis remains a common and deadly condition that occurs when the body reacts to an infection in the bloodstream. Scientists know little about the early stages of the condition; however, physicians must act fast. Every hour that passes without one or more of the few treatments available increases the risk of death.
Cell stress in combination with an altered microbiota in the colon drives tumour growth. Previously, it was assumed that this combination only contributes to inflammatory intestinal diseases.
A team of researchers at the University of Cologne's Faculty of Medicine and the German Center for Infection Research (DZIF) use a novel immunochromatographic method to detect bacteria that are resistant to the antibiotic group carbapenemes within 20 to 45 minutes from blood cultures with 100 percent certainty.
Alcohol-based hand sanitisers have been a mainstay in hospital hygiene for decades. But now, strains of antibiotic-resistant bacteria show signs of overcoming these handwashing agents as well. Does this mean we should just stop sanitising our hands? Not so fast, say researchers from Melbourne – however, hospitals now need to re-think their strategies to protect their patients from deadly…
Imagine a pathogen that infects completely healthy people and can cause blindness in one day and flesh-eating infections, brain abscesses and death in just a few days. Now imagine that this pathogen is also resistant to all antibiotics.
Researcher have created an ingestible sensor to non-invasively monitor indicators of disease in the stomach and intestines.
Since 2013, a new strain of meningococcal bacteria has spread rapidly in Niger and Nigeria, leading to large-scale outbreaks of meningitis. Analysis of the genetic material shows that with just two gene mutations, harmless bacteria transform into a strain that could cause major epidemics in these two countries.
Scientists from the German Cancer Research Center (DKFZ) have been studying how the immune system succeeds in keeping pathogens in check. For the first time, the researchers have now discovered antibodies that are capable of disarming not only one specific bacterium but a whole variety of microorganisms at once. The newly discovered antibodies recognize a tiny sugar structure found on the surface…
Anthrax, plague and tularemia are three potent agents terrorists would be likely to use in an attack, according to the Centers for Disease Control and Prevention. Each is highly and quickly lethal to humans. But there are no licensed vaccines for tularemia and plague, and although there is an anthrax vaccine, it requires a burdensome immunization schedule and has severe side effects. Now, a…
A little-explored group of immune cells plays an important role in the regulation of intestinal bacteria. Changing metabolic states of the microbes have an effect on defense cells at different stages of alert or rest, as researchers from the Department of Biomedicine at the University and University Hospital of Basel report in the journal "Mucosal Immunology." It is known that the…
A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…
Partners who could hardly be further apart – yet have a lot in common – have united to fight resistant pathogens. The International Consortium for Anti-Infective Research (iCAIR) was founded last January. Hanover Medical School (MHH) and the Fraunhofer-Institute for Toxicology and Experimental Medicine (ITEM) are participants in Germany. The third partner, the Institute for Glycomics (IfG) at…
Beta-lactam antibiotics, including penicillin, are one of the most widely used classes of antibiotics in the world. Though they’ve been in use since the 1940s, scientists still don’t fully understand what happens when this class of drugs encounters bacteria. Now, researchers at the University of Notre Dame have elucidated how an enzyme helps bacteria rebound from damage inflicted by…
Researchers from the University of Illinois at Chicago and Nosopharm, a biotechnology company based in Lyon, France, are part of an international team reporting on the discovery of a new class of antibiotics. The antibiotic, first identified by Nosopharm, is unique and promising on two fronts: its unconventional source and its distinct way of killing bacteria, both of which suggest the compound…
While gastritis and gastric ulcer disease used to be put down to stress and dietary factors, it was discovered in the 1980s that the actual culprit is infection with a bacterium, H. pylori. This pathogen is now classed as a type I carcinogen by the WHO, as it is the major risk factor for development of gastric carcinoma. Attempts to develop a vaccine against H. pylori have been unsuccessful and…
