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…
Mologic Ltd, which develops powerful, personalised diagnostics to improve the lives of patients, and Fraunhofer Centre for Applied Photonics (Fraunhofer CAP), a world-leading centre in the field of applied laser research and development, announced they are working together to develop a rapid, point-of-care test to immediately diagnose bacterial urinary tract infections (UTIs) and any associated…
WHO’s first release of surveillance data on antibiotic resistance reveals high levels of resistance to a number of serious bacterial infections in both high- and low-income countries. WHO’s new Global Antimicrobial Surveillance System (GLASS) reveals widespread occurrence of antibiotic resistance among 500 000 people with suspected bacterial infections across 22 countries.
Bacteria are stealthy organisms. They can multiply in minutes and evolve to survive what we throw at them—including antibiotics. The World Health Organization calls antibiotic resistance “one of the biggest threats to global health, food security, and development today.” Each year, about 2 million people in the United States become infected with antibiotic-resistant bacteria, according to…
Joint replacement surgery carries the risk of developing an infection in the replaced joint, which can lead to a so-called revision or re-do of the joint replacement. However, current diagnostic practices can fail to detect bacteria in 30-50 percent of clinical cases, complicating or delaying appropriate treatment. Thomas Jefferson University researchers have found that genomic analysis using…
Bacteria not only develop resistance to antibiotics, they also can pick it up from their rivals. In a recent publication, Researchers from the Biozentrum of the University of Basel have demonstrated that some bacteria inject a toxic cocktail into their competitors causing cell lysis and death. Then, by integrating the released genetic material, which may also carry drug resistance genes, the…
An SLAS Technology review article by Yiyan Li, Xing Yang and Weian Zhao of University of California, Irvine highlights and synthesizes representative emerging micro- and nanotechnologies, as well as automated systems for bacterial identification (ID) and antibiotic susceptibility testing (AST), including both phenotypic and molecular methods and those at the point-of-care (POC) setting. Also…
Antibiotic resistant bacteria lead to infections that are difficult to treat, particularly in hospitals. Multidrug-resistant Escherichia coli bacteria which have developed special enzymes that render antibiotics ineffective frequently cause such infections. DZIF scientists from Gießen University examined these bacteria more precisely and discovered a strain of Escherichia coli that has been…
CAU research team proves, for the first time, that there is close cooperation between the nervous system and the microbial population of the body.
Chronic lung infections caused by the bacterium Pseudomonas aeruginosa require complex and, in most cases, long-term treatment with antibiotics—new medication is badly needed.
Researchers at the Swedish Medical Nanoscience Center at Karolinska Institutet have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth.
‘The literature on hand washing, while extensive, often contains conflicting data, and key variables are only superficially studied, or not studied at all. Some hand washing recommendations are made without scientific support, and agreement between recommendations is limited,’ explained Professor Donald W Schaffner at Rutgers University, New Jersey, USA, who has led a team of researchers to…
While new agents to fight virulent pathogens are in the pipeline, a new study pinpoints where a recent addition is already being applied in the clinic.
Survival of mass extinctions helps to explain near indestructible properties of hospital superbugs.
The majority of women suffering with pain when urinating, or needing to urinate often or urgently probably do have a bacterial infection, even when nothing is detected by standard urine testing.
SpeeDx Pty. Ltd., a developer of innovative molecular diagnostic solutions, has signed an agreement with Thermo Fisher Scientific, the world leader in serving science. The announcement was made at the 27th European Congress of Clinical Microbiology and Infectious Disease (ECCMID) in Vienna to submit its ResistancePlus MG Test for the detection of Mycoplasma genitalium to the US Food & Drug…
Foods should be investigated as a potential source of spread of Clostridium difficile, according to research presented at the 27th ECCMID [1].
Following a top level EU report showing antimicrobial resistance (AMR) remains high, Professor Mike Catchpole, Chief Scientist at the European Centre for Disease Prevention and Control (ECDC), has warned that stricter use of antibiotics is critical.
Philips and Diagnostics Development, a P&M Venge company, evaluate the novel human neutrophil lipocalin (HNL) biomarker for the rapid detection of bacterial infection. Based on Philips’ Minicare I-20 handheld diagnostics platform, the Minicare HNL assay is recognized for its potential to provide physicians with 10-minute confirmation of bacterial infection, helping to ensure that…
Using computer-based simulations and mouse experiments, researchers at the Helmholtz Centre for Infection Research (HZI) in Braunschweig and at the Otto von Guericke University Magdeburg (OVGU), have disentangled the effects of pro-inflammatory signalling molecules on the postinfluenza susceptibility to pneumococcal coinfection.
Adding UV light to standard cleaning cut transmission of 4 resistant bacteria by 30 percent
Magnets instead of antibiotics could provide a possible new treatment method for blood infection. This involves the blood of patients being mixed with magnetic iron particles, which bind the bacteria to them after which they are removed from the blood using magnets. The initial laboratory tests at Empa in St. Gallen have been successful, and seem promising.
Experts at the European Committee on Antimicrobial Susceptibility Testing (EUCAST), who define the optimal drug concentrations to inhibit the growth of pathogens, have found that genetic methods cannot yet be used to test for susceptibility in a number of important bacterial species.
