Research has identified critical factors that enable dangerous bacteria to spread disease by surviving on surfaces in hospitals and kitchens. The study into the mechanisms which enable the opportunistic human pathogen Pseudomonas aeruginosa to survive on surfaces, could lead to new ways of targeting harmful bacteria. To survive outside their host, pathogenic bacteria must withstand various…
A consortium of researchers from Russia, Belarus, Japan, Germany and France led by the Skolkovo Institute of Science and Technology have uncovered the way in which Mycobacterium tuberculosis survives in iron-deficient conditions by utilizing rubredoxin B, a protein from a rubredoxin family that play an important role in adaptation to changing environmental conditions.
Antimicrobial technologies such as coatings and textiles containing silver and copper are helping people during the Covid-19 pandemic by ensuring that whatever they touch, whether that is a door handle or their own mask, is free from live SARS-CoV-2 particles. But how exactly do these antimicrobial technologies work? How can a silver, copper or even polymeric coating kill microorganisms such as…
Potentially game-changing research led by McMaster University scientists may finally bring relief to millions of people worldwide living with Crohn’s disease. Investigator Brian Coombes said his team identified a strain of adherent-invasive E-coli (AIEC) that is strongly implicated in the condition and is often found in the intestines of people with Crohn’s disease. “If you examine the gut…
Researchers have developed an innovative method to disrupt the formation of biofilms and thus facilitate the treatment of infections with Pseudomonas aeruginosa.
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…
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…
For several years, scientists worldwide have been investigating the extent to which microorganisms living in and on the human body influence central life processes and thus health and disease. Today they assume that there is a connection between the totality of the microbial colonization in the human body, called the microbiome, and the development of diseases. Chronic inflammatory bowel disease…
The variety and volume of bacteria in the gut, known as the microbiome, may influence the severity of Covid-19 as well as the magnitude of the immune system response to the infection, suggests research published online in the journal Gut. Imbalances in the make-up of the microbiome may also be implicated in persisting inflammatory symptoms, dubbed ‘long Covid’, the findings suggest. Covid-19…
A microbe found in the colon and commonly associated with the development of colitis and colon cancer also may play a role in the development of some breast cancers, according to new research from investigators with the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy. Breast tissue cells exposed to this toxin retain a long-term memory, increasing the…
Researchers at the Francis Crick Institute and the University of Western Australia have developed a new imaging method to see where antibiotics have reached bacteria within tissues. The method could be used to help develop more effective antibiotic treatments, reducing the risk of antibiotic resistance.
The type and abundance of bacteria found in the mouth may be linked to lung cancer risk in non-smokers, finds the first study of its kind, published online in the journal Thorax.
For the first time ever, expansion microscopy allows the imaging of even the finest details of cell membranes. This offers new insights into bacterial and viral infection processes.
Bacterial infections have become one of the biggest health problems worldwide, and a recent study shows that COVID-19 patients have a much greater chance of acquiring secondary bacterial infections, which significantly increases the mortality rate.
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.
Russian tech company Connectome.ai is bringing its innovative Directiva.ai hand hygiene teaching and monitoring system to two major clinics owned by the European Medical Center group, the leading private healthcare provider in Moscow and the surrounding region.
Researchers have shown why hospital germs adhere strongly to surfaces from which water simply rolls off, but bind so poorly to surfaces that are easily wetted by water.
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.
Several thousand strains of bacteria live in the human gut. Some of these are associated with disease, while others have beneficial effects on human health. Figuring out the precise role of each of these bacteria can be difficult, because many of them can’t be grown in lab studies using human tissue. This difficulty is especially pronounced for species that cannot live in oxygen-rich…
The human species maintains symbiotic relationships with a multitude of microbial organisms that colonise the inside as well as the surface of the body. Scientists, for a long time, underestimated the significance of these organisms for humans.
Scientists from the German Cancer Research Center (DKFZ) and the Hebrew University in Jerusalem demonstrated in mice that intestinal bacteria reprogram DNA activity in cells of the gut mucosa and thus have a considerable impact on the development of the healthy gut.
A newly published paper details a research breakthrough that provides a promising starting point for scientists to create drugs that can cure Clostridium difficile (C. diff) — a virulent health care-associated infection that causes severe diarrhea, nausea, internal bleeding, and potentially death. The bacteria affects roughly half-a-million Americans and causes nearly 15,000 deaths in the U.S.…
Researchers at the University of Exeter first identified a gene in the 'hospital bug' Clostridioides difficile responsible for producing a protein that aids in binding the bacteria to the gut of its victims. In collaboration with researchers at Paris-SUD University, they then showed that mice vaccinated with this protein generated specific antibodies to the protein – and that C. diff that did…
Scientists from Scotland are developing a low cost, rapid diagnostic sensor test which aims to show the susceptibility of bacteria to antibiotics within 45 minutes. Laboratory testing of samples can take up to two days and the new test aims to allow doctors to be able to prescribe the correct antibiotic to a patient for an infection more quickly. In a research paper published in the journal…
All living creatures – from the simplest animal and plant organisms right up to the human body – are colonised by numerous microorganisms. They are thus in a functional relationship with these microbes, and together form a so-called metaorganism. The investigation of this symbiotic cooperation between host organism and microorganisms is a key challenge for modern life sciences research. The…
