Antibiotic resistance: a global problem in urgent need of solutions

Antibiotics have been at the heart of modern healthcare since the 1950s. They are prescribed prior to an operation to minimise the risk of infection after the operation. Or antibiotics are prescribed…

Five-minute MRSA detection with aptasensor swabs

An international research team from Saudi Arabia, Germany, and Jordan has developed a novel pathogen aptasensor swab designed to qualitatively detect, within five minutes, any methicillin-resistant…

Higher doses of antibiotic may strenghten certain bacteria

Using higher doses of antibiotics in a bid to tackle the growing problem of drug resistance may end up strengthening certain bacteria, according to research that highlights a previously unthought-of…

New material to protect against antibiotic resistant bacteria

Researchers at Chalmers University of Technology, Sweden, have developed a new material that prevents infections in wounds – a specially designed hydrogel, that works against all types of bacteria,…

A new tool to combat superbugs

Defeating antibiotic resistant bacteria with 'molecular tweezers'

Antibiotic resistant bacteria are a looming super threat – heralding a time when our drugs will no longer be effective against prevalent infections. Hospitals are already coping with treatment-resistant bacterial infections. Cognizant of the threat and thinking outside the box, BGU scientists and German and American colleagues have developed a pair of 'molecular tweezers' to destroy the biofilm…

WHO reports global shortage of innovative antibiotics

The world is still failing to develop desperately needed antibacterial treatments, despite growing awareness of the urgent threat of antibiotic resistance, according to a new report by the World Health Organization. WHO reveals that none of the 43 antibiotics that are currently in clinical development sufficiently address the problem of drug resistance in the world’s most dangerous bacteria.…

M.O. of Darobactin unveiled

Novel antibiotic deceives bacteria through mimicry

An increasing number of bacterial pathogens are resistant to antibiotics. And the most dangerous pathogens share a common feature: a double membrane that is difficult to penetrate. Even when antibiotic agents are able to break into this shell, the bacteria just pump them right out again. But a recently discovered compound called Darobactin manages to circumvent these protective measures and kill…

Covid-19 impact on vaccination

Antibiotic resistance could make diphtheria ‘major global threat’ again

Diphtheria – a relatively easily-preventable infection – is evolving to become resistant to a number of classes of antibiotics and in future could lead to vaccine escape, warn an international team of researchers from the UK and India. The researchers, led by scientists at the University of Cambridge, say that the impact of Covid-19 on diphtheria vaccination schedules, coupled with a rise in…

Mutations help bacteria resist antibiotic treatment

Bacteria have many ways to evade the antibiotics that we use against them. Each year, at least 2.8 million people in the United States develop an antibiotic-resistant infection, and more than 35,000 people die from such infections, according to the U.S. Centers for Disease Control. Most of the mutations known to confer resistance occur in the genes targeted by a particular antibiotic. Other…

Revealing the mechanisms

Unlocking ‘the shape of water’ to fight antibiotic resistance

New high-resolution structures of the bacterial ribosome determined by researchers at the University of Illinois Chicago show that a single water molecule may be the cause — and possible solution — of antibiotic resistance. The findings of the new study are published in the journal Nature Chemical Biology. Pathogenic germs become resistant to antibiotics when they develop the ability to…

Antibacterial cellulose

A wound dressing that kills bacteria

In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently. If germs invade a wound, they can trigger a long-lasting infection that may fail to heal or even spread throughout the body, leading to…

'Ancientbiotics'

Medieval medicine against antibiotic resistance

Antibiotic resistance is an increasing battle for scientists to overcome, as more antimicrobials are urgently needed to treat biofilm-associated infections. However, scientists from the School of Life Sciences at the University of Warwick say research into natural antimicrobials could provide candidates to fill the antibiotic discovery gap.

Improving the efficiency of antibacterial surfaces

Resistance to antibiotics has become a serious public health problem. Hospital infections, prostheses or surgical implants that become infected and do not respond to treatment are a real challenge to the research community, which has been seeking alternatives for effectively eliminating these bacteria for years. In 2012 the researchers from the Department of Chemical Engineering of the…

Researchers find 'resistance resistant' antibiotic

University of Melbourne researchers are finding ways to beat dangerous superbugs with ‘resistance resistant’ antibiotics, and it could help in the fight against coronavirus (COVID-19) complications. As bacteria evolve, they develop strategies that undermine antibiotics and morph into ‘superbugs’ that can resist most available treatments and cause potentially lethal infections. The…

Probiotic drinks vs antibiotic resistance?

A probiotic drink could become a promising new weapon in the battle against antibiotic resistant bacteria, after a team of scientists at the University of Birmingham engineered and patented a key genetic element that can tackle the genetic basis of resistance. The team is now seeking funding for a clinical trial for the drink which has potential to work against many resistant bacteria commonly…

Potent antimicrobial to fight staph infections

Research led by scientists from McMaster University has yielded a potent antimicrobial that works against the toughest infectious disease strains. The find could be the beginning of developing new therapeutics to combat drug-resistant infections. The discovery is important as it is directly related to the development of Staphylococcus aureus diseases, known popularly as staph infections, which…
