Wearable sensor to monitor ‘last line of defense’ antibiotic
Researchers at Sandia National Laboratories have combined earlier work on painless microneedles with nanoscale sensors to create a wearable sensor patch capable of continuously monitoring the levels of a ‘last line of defense’ antibiotic.
Ultrathin nanotech promises to help tackle antibiotic resistance
Researchers have invented a nano-thin superbug-slaying material that could one day be integrated into wound dressings and implants to prevent or heal bacterial infections.
Phage pioneer Graham Hatfull helps when antibiotics can’t
Graham Hatfull has pioneered the use of bacteriophages, or just “phages,” to combat antibiotic resistant infections. He was honored with the Gardner Middlebrook Lifetime Achievement award for his research.
Preeminent expert on antibiotic resistance, Dele Ogunseitan, available to speak on superbugs
Oladele “Dele” Ogunseitan, PhD serves as the University of California Presidential Chair and Professor of Population Health and Disease Prevention at the University of California, Irvine Program in Public Health. He is a renowned expert in the field of global…
A Quick New Way to Screen Virus Proteins for Antibiotic Properties
A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Our scientists are making it easier to study them.
A Pitt lab shows phage attacks in new light
New methodology and tools his team developed by phage expert Graham Hatful provides the opportunity to watch in unprecedented detail as a phage attacks a bacterium.
RUSH, Discovery Partners Institute Awarded CDC Contract to Test Wastewater for Antibiotic Resistant Organisms
Under a four-year $2 million contract awarded by the Centers for Disease Control and Prevention, scientists from RUSH and the Discovery Partners Institute will test wastewater from long-term care facilities to identify antibiotic-resistant organisms.
Don’t give up the fight. Read the latest news about drug and antibiotic resistance
Here are some of the latest articles that have been added to the Drug Resistance channel on Newswise, a free source for journalists.
Mystery mechanism in small peptide shows big promise for fighting antibiotic-resistant bacteria
Using neutrons, researchers at Oak Ridge National Laboratory pieced together the molecular mechanics behind a peptide’s ability to deal significant damage to bacterial cells. Their findings could inform new therapeutic strategies for treating bacterial infections where antibiotics have fallen short.
New Model for Antibacterial Mechanism
Biologists have discovered an aberrant protein that’s deadly to bacteria. The discovery could help scientists unravel the lethal mechanism of certain antibiotics—and potentially point the way to future antibacterial drugs.
Science Snapshots from Berkeley Lab
An experiment to study gravity at the quantum scale, insights into an antibiotic-building enzyme, and the backstory of an incredible new protein prediction algorithm are featured in this month’s roundup of science highlights.
Grant to help fill gaps in how livestock manure management affects antibiotic resistance
Iowa State University researchers received a $1 million grant to study how manure management systems in livestock production may give rise to antibiotic resistance. Human, animal and environmental health interact in complex ways that influence the pace at which antibiotic resistance spreads, and the researchers hope their work will shed light on these connections.
New cell profiling method could speed TB drug discovery
A new cell profiling technology combines high throughput imaging and machine learning to provide a rapid, cost-effective way to determine how specific compounds act to destroy the bacterium that causes tuberculosis. It could speed discovery of anti-TB drugs and be applied to other pathogens.
Pandemic could make drug resistance epidemic worse
Researchers fear that widespread use of antibiotics during the coronavirus pandemic will add fuel to the fire, making more common infections that were once treatable possibly life threatening.
Exploring Nature’s Treasure Trove of Helpful Compounds
Compounds that plants, fungi, bacteria, and animals produce can sometimes help people as well. In fact, many medicines, molecules used in research, and other useful compounds originated in nature. Learn more about recent discoveries in the fascinating field of natural products research.
Discovery reveals antibiotic-resistant strep throat may be too close for comfort
Infectious disease scientists identified strains of group A streptococcus that are less susceptible to commonly used antibiotics, a sign that the germ causing strep throat and flesh-eating disease may be moving closer to resistance to penicillin and other related antibiotics known as beta-lactams.
New Portable Tool Analyzes Microbes in the Environment
Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms – too tiny to be seen by the naked eye – and their response to threats to their ecosystems. Rutgers researchers have created just such a tool, a portable device that could be used to assess microbes, screen for antibiotic-resistant bacteria and analyze algae that live in coral reefs. Their work is published in the journal Scientific Reports.
Disarming bacteria with mucus and phages
Millions of people are treated with antibiotics each year for infections or as a preventative measure. Two teams of NIBIB-funded scientists have been working to find alternative solutions for treating bacterial infections, especially antibiotic-resistant bacteria.
Taking One for the Team: How Bacteria Self-Destruct to Fight Viral Infections
UC San Diego School of Medicine researchers have discovered how a new immune system works to protect bacteria from phages, viruses that infect bacteria — new information that could be leveraged to improve treatment of multidrug-resistant bacterial infections by refining phage therapy.
Why It Matters: Prescription for Disaster
Bacteria are becoming increasingly resistant to antibiotics. A major cause is their overuse in both humans and animals. At the same time, a lack of financial incentives is setting back efforts to discover new classes of antibiotics. The problem is both global and local, and without new initiatives, many common medical conditions could become deadly once again.
Bacterial Resistance to Two Critical Antibiotics Widespread in Southeast Asia
Resistance to two critical antibiotic types, one a “drug of last resort” when all others fail against some “superbugs,” are widely distributed in Southeast Asia, raising the risk of untreatable infections, say a team of investigators led by Georgetown University Medical Center.
