Two-dimensional (2D) cultured cell lines and animal models have been the principal research tools for the past decade, but have several shortcomings. Three-dimensional cell cultures, or organoids, show great promise here.
A comprehensive assessment of scientific literature has uncovered empirical evidence that more than 58% of human diseases caused by pathogens, such as dengue, hepatitis, pneumonia, malaria, Zika, have been aggravated by climatic hazards.
A worldwide consortium aims to equip researchers in low- and middle-income countries (LMICs) with cheap and accessible methods for sequencing large collections of bacterial pathogens.
The sharpest images ever of living bacteria have been recorded by researchers at University College London, revealing the complex architecture of the protective layer that surrounds many bacteria and makes them harder to be killed by antibiotics.
A Danish pipetting robot is automating Covid testing processes in hospitals around Europe. The robot, called flowbot ONE, significantly reduces the time it takes for laboratories to produce results for patients to tell them whether they are infected with Covid-19.
The current outbreak of the novel coronavirus disease (COVID-19) is making headlines by the minute. However, some less-than-trustworthy advice can be found among the information. Understandably, many people are concerned and confused. To prevent unnecessary panic, the World Health Organisation (WHO) has assembled advice for the public. Is it safe to receive parcels from China? Will sesame oil…
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…
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…
A team of scientists led by researchers at the University of Georgia Center for Food Safety in Griffin has developed a machine-learning approach that could lead to quicker identification of the animal source of certain Salmonella outbreaks. In the research, published in Emerging Infectious Diseases, Xiangyu Deng and his colleagues used more than a thousand genomes to predict the animal sources,…
The holiday season just wouldn't be the same without delicious Christmas cookies. Impatience in the bakery, however, might be penalized with some unpleasant or even dangerous side-effects. Bruce Ruck, managing director of the New Jersey Poison Control Center at Rutgers University Medical School, talks about the risks associated with eating raw cookie dough: “It’s a potential recipe for food…
Scientists of the Helmholtz Centre for Infection Research (HZI) have now dissected the precise molecular mechanisms of WAVE complex activation, occurring in a process involving separable, independent steps.
Sepsis remains a common and deadly condition that occurs when the body reacts to an infection in the bloodstream. Scientists know little about the early stages of the condition; however, physicians must act fast. Every hour that passes without one or more of the few treatments available increases the risk of death.
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.
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.
Hospital-acquired Clostridium difficile infection (CDI) is on the rise. Symptoms range from non-typical mild diarrhoea that can develop into pseudomembranous colitis up to a toxic megacolon, which often leads to death.
Thousands upon thousands of humans have taken and are continuing to take flight from wars, persecution and economic stress, seeking the chance of survival in European and other countries. They arrive not only physically exhausted, but also in mourning for those killed in their own countries, or during hellish journeys – therefore many also suffer unimaginable mental traumas. Clearly they need…
Data presented at the European Congress of Clinical Microbiology and Infectious Diseases diseases has highlighted how a recently-discovered mechanism could mean one of the last-resort antibiotics is under threat. Evidence put before ECCMID suggested the genetic mechanism allowing bacteria to develop and transfer resistance to colistin has been present in several countries around the world –…
Several bacterial species have pledged promise in fighting tumors. However, most of them are pathogens. In order to use them as a weapon against cancer and other diseases in humans, researchers must find a balance between their therapeutic aggressiveness and safety for the patient. To overcome this problem, researchers at the Helmholtz Centre for Infection Research (HZI) have shifted their focus…
Researchers presented findings on the prevalence of the mcr-1 gene, a transferable genetic mechanism of antimicrobial-resistance to colistin - the last resort antibiotic in a number of circumstances. At a session dedicated to late-breaking abstracts on colistin resistance, researchers presented evidence on the prevalence of the gene in bacteria (including Enterobacteriaceae such as Escherichia…
Iron nanoparticles injected before magnetic resonance imaging can make tissues more visible and the same nanoparticles may allow doctors to precisely target tumors with new medicines. However, among the challenges to the practical use of nanoparticles in the human body is what scientists refer to as lack of “hemocompatibility” – nanoparticles tend to be attacked and cleared by the immune…
The human gut literally teems with microorganisms from at least 1,000 different species that are increasingly considered to be a valuable resource for the prediction, aetiology and prognosis of disease. Due to continual contact with the environment, primarily via food, the gut is susceptible to infection when a virus, parasite or bacterium enters and disrupts normal gut microbiota (or flora).
Approach could improve treatment of drug-resistant infections. Combining a PET scanner with a new chemical tracer that selectively tags specific types of bacteria, Johns Hopkins researchers - working with mice report - have devised a way to detect and monitor in real time infections with a class of dangerous Gram-negative bacteria.
Bacteria, viruses and fungi are killed on copper surfaces within seconds. This powerful germicidal effect, termed ‘contact killing’, is increasingly noted by hospitals due to several recent studies that confirm its antimicrobial effects.
The vital, routine task of plate streaking to isolate a pure culture is inefficient and time-consuming, significantly slowing microbiologists' responses.
Researchers funded by the European Union have devised OptoLabCard, a system that prepares samples and performs DNA tests on bacteria in a portable, easily used, cost-effective lab-on-a-chip.
Engineers from the University of Michigan are seeking to develop a "lab-on-a-chip" kit that people can assemble on their own. It could bring a new generation of instant home tests checking out for illnesses, food contaminants and toxic gases.
The UK's MRSA rates have been declining since 2006 — and this year could be 50% lower than in 2004. This increasing control over dangerous pathogens has not been achieved without considerable hospital staff efforts, relentless public and government pressures on them, and in-house malcontent about the out-sourcing of cleaning work. Given the cost of nosocomial infections to patients, the NHS…
Endoscopic procedures, which are well established in the diagnosis and therapy of gastrointestinal diseases, not only carry procedural risks but also the risk of endoscopy associated infections.
Globally, about two million people die each year after consuming spoilt food, according to the World Health Organisation (WHO).
