In a preclinical study, NIH scientists found that the commonly used antibiotic methacycline may be effective at combating the neurological problems caused by Zika virus infections.
For a slow-growing microbe that multiplies infrequently, Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB) has long puzzled researchers as to how it develops resistance to antibiotics so quickly, in a matter of weeks to months.
The fight against bacterial infections, especially those caused by resistant pathogens, is in full swing with the search for new antibiotic agents. The aim is to identify substances that attack the pathogens in a truly novel way. The team at the Center for Systems-Based Antibiotic Research (Cesar) at Ruhr-Universität Bochum (RUB) has described in two publications how assess if a new antibiotic…
Researchers at the University of Sheffield have developed a new compound that is able to kill both gram-positive and gram-negative antibiotic-resistant bacteria.
Disruption of gut bacteria by antibiotics soon after birth can affect the maturation of the immune system, say researchers at Rutgers University-New Brunswick. Even short, single antibiotic courses given to young animals can predispose them to inflammatory bowel disease (IBD) when they are older, according to their research. The study, published in Genome Medicine, provides further evidence…
Imagine a dressing that releases antibiotics on demand and absorbs excessive wound exudate at the same time. Researchers at Eindhoven University of Technology (TU/e) hope to achieve just that, by developing a smart coating that actively releases and absorbs multiple fluids, triggered by a radio signal. This material is not only beneficial for the healthcare industry, it is also very promising in…
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…
Layering minute amounts of Manuka honey between layers of surgical mesh acts as a natural antibiotic that could prevent infection following an operation, new research has shown. Meshes are used to help promote soft tissue healing inside the body following surgery and are common in operations such as hernia repair. However, they carry with them an increased risk of infection as the bacteria are…
PHE’s latest English Surveillance Programme for Antimicrobial Utilisation and Resistance (ESPAUR) report shows that there were an estimated 61,000 antibiotic resistant infections in England during 2018, a 9 percent rise from 2017.[i]
Many life-threatening bacteria are becoming increasingly resistant to existing antibiotics. Swiss researchers co-headed by the University of Zurich have now discovered a new class of antibiotics with a unique spectrum of activity and mechanism of action. By disrupting outer membrane synthesis, the antibiotics effectively kill Gram-negative bacteria. According to the World Health Organization…
Scientists at the University of Surrey have discovered that a natural antioxidant commonly found in green tea can help eliminate antibiotic resistant bacteria...
Bacteria are becoming increasingly resistant to common antibiotics. Often, resistance is mediated by resistance genes, which can simply jump from one bacterial population to the next. It’s a common assumption that the resistance genes spread primarily when antibiotics are used, a rationale backed up by Darwin's theory: only in cases where antibiotics are actually being used does a resistant…
Cigarette smoke can make MRSA bacterial strains more resistant to antibiotics, new research from the University of Bath has shown. In addition cigarette smoke exposure can make some strains of Staphylococcus aureus – a microbe present in 30-60% of the global population and responsible for many diseases, some fatal – more invasive and persistent, although the effect is not universal across all…
Many countries across the world are challenged with a rising number of incidences of multi-drug resistant (MDR) organisms infecting the population, and for several years, a clear pattern of increased resistance has emerged in southern and eastern European countries. For example, in countries such as Italy, a reduced number of therapeutic options remain available for highly pathogenic infections,…
As leaders gather for the International Ministerial Conference on antimicrobial resistance (AMR), hosted by the government of The Netherlands and organised in close cooperation with the FAO, OIE and WHO, experts and responsible manufacturers are calling for a 'One Health' approach to AMR and recognition of the impact of antibiotic production on the environment. "With two thirds of the worlds…
Bacteria have fascinating properties. They adapt excellently to their respective environment, and they existed long before humans. Their toughness has led to the fact that bacteria have successfully spread all over the world for three billion years – even in places where humans could not survive, for example in the hottest springs and in the coldest places on earth. However, they were only…
Imperial medical students have helped to devise a new type of ‘decoy’ drug to tackle infections that are resistant to antibiotics. In lab tests on bacterial cultures, the new drug successfully killed a strain of drug-resistant bacteria. It works by delivering two antibiotics, one of which is effectively hidden. When the bacteria fight against the first ‘decoy’ antibiotic, this action…
Researchers at Washington University School of Medicine in St. Louis have found, in mice, that treatment with an antibiotic reduces the size of lesions caused by endometriosis. The researchers are planning a large, multicenter clinical trial to test the drug metronidazole in women who have the painful condition. The study is published online April 30 in the journal Human Reproduction.…
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…
BioMérieux and the Laboratory of Medical Microbiology at the University of Antwerp announced at ECCMID (European Congress of Clinical Microbiology & Infectious Diseases) the 2018 results of the Global Point Prevalence Survey (GLOBAL-PPS), a study of antibiotic use and antimicrobial resistance (AMR) in hospitals around the world. Since its launch in 2015, this survey has been conducted in…
Sixty-two percent of Germans fear antibiotic resistance, according to a survey recently conducted by the German Federal Institute for Risk Assessment. ‘Patients colonised by multi-resistant pathogens are particularly scared. But many of these fears are rooted in misunderstandings,’ explained Professor Mathias Pletz at the Congress for Infectious Diseases and Tropical Medicine (KIT).
Antimicrobial resistance is a global issue, with 700,000 deaths per year and 10 million expected deaths by 2050, according to predictions. Appropriate antimicrobial therapy can help to save lives, and a long awaited cure for carbapenemase-producing enterobacteriaceae (CPE) will soon be released, according to eminent Spanish expert Jose Mensa Pueyo, speaking at a Madrid meeting in March. The past…
Early detection and confirmation of carbapenemase-producing enterobacteriaceae (CPE) are essential when choosing the appropriate antimicrobial therapy and to implement infection control measures. Here, a leading Spanish microbiologist reviews an arsenal of tools currently available to clinicians. Resistance to beta-lactam antibiotics in enterobacteriaceae (EBc) is due to one or more of these…
By studying fish raised in aquaculture, researchers from the Helmholtz Zentrum München, the University of Copenhagen and the University of Campinas in Brazil have shed new light on the mechanisms by which antibiotic resistance genes are transferred between bacteria. According to the study published in the journal ‘Microbiome’, those mechanisms are more varied than previously thought. “In…
Hip and knee joint surgeries are among the most common procedures in orthopaedics and trauma surgery and complications can occur. Rare, but serious, among these is periprosthetic joint infection (PJI), which causes high costs in healthcare and stress for patients. PJI is caused by microorganisms that form a biofilm on the surface of the implant and, in this sessile state, they are difficult to…
