Systems biology of antibiotics

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…

'Decoy' antibiotics dupe bacteria’s defences

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…

Endometriosis: Antibiotic could be key to treatment

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.…

How bacteria can adapt to resist antibiotic treatment

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…

Myths and truths about antibiotics, antiseptics and vaccination

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, Director of the Institute of Infection Medicine and Hospital Hygiene at…

Carbapenemase producing enterobacteriaceae

Detecting drug-resistant CPE quickly is still a challenge

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…

Apocalypse postponed: upcoming antibiotics bring hope

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…

Alarming results

Antibiotic resistance spreads faster than previously thought

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…

Local antibiotics improve results

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…

Antibiotic stewardship

Screening with multiplexed kits

Antibiotic stewardship is becoming a critical concern in hospitals as antibiotic resistance spreads globally and some organisms become resistant to antibiotics of last resort. Molecular diagnostics can play a role in antibiotic stewardship programs by providing timely and accurate advice to clinicians on which antibiotics to use, Professor Keith Stanley advises. "Antibiotic resistance in the…

Ultrasound aids ear infection diagnosis

Although traditionally an imaging modality, ultrasound also has applications as a measurement tool. An innovative application is to assess ear infections. Otitis Media (OM), a middle ear infection, is the number one indication for antibiotic prescriptions for children and the leading cause for surgery. This problem is global. Nearly every child will suffer at least one middle ear infection severe…

No chance for bacteria on implants

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…

‘Why not take a risk?’ belief boosts antibiotic overuse

Antibiotics are mostly prescribed for acute respiratory infections (ARIs), yet most of these infections are viral. A new study shows that inappropriate antibiotics prescriptions are widespread, contributing dangerously helping antibiotic-resistant organisms to grow. Overuse could be due to attitudes among patients and clinicians, current George Washington University research suggests.

Bedside testing can prevent antibiotic-induced hearing loss in new-borns

More than a million neonatal deaths worldwide each year are estimated to be due to sepsis. In the UK there are approximately 90,000 admissions to neonatal intensive care units per year. Nearly all these patients receive antibiotic therapy during their hospital stay, but babies with a specific genetic change can suffer irreversible hearing loss as a result. Now, in a collaboration between…

Antibiotic combination against multidrug-resistant pathogens

Gram-negative pathogens are responsible for half of all healthcare-associated infections and their ability to resist traditional antibiotics makes them more dangerous for seriously ill patients in a healthcare setting. The need for new approaches to treat these pathogens is essential and there are a number of trials trying to find suitable answers. One of them is the RESTORE-IMI 1 pivotal Phase…

Oral antibiotics may raise risk of kidney stones - especially in kids

Pediatric researchers have found that children and adults treated with some oral antibiotics have a significantly higher risk of developing kidney stones. This is the first time that these medicines have been linked to this condition. The strongest risks appeared at younger ages and among patients most recently exposed to antibiotics. “The overall prevalence of kidney stones has risen by 70…

Antibiotic resistance can be caused by small amounts of antibiotics

Antibiotic-resistant bacteria are a global and growing problem in health care. To be able to prevent further development of resistance developing, it is important to understand where and how antibiotic resistance in bacteria arises. New research from Uppsala University shows that low concentrations of antibiotics, too, can cause high antibiotic resistance to develop in bacteria. In the present…
