Communicable diseases remain one of the major causes of mortality worldwide. There are disparities in the numbers of individuals affected by disease between low-and-middle-income countries and those in developed nations. Microbes will play in important role in drug discovery: producing anticancer drugs and antimicrobials. Applying One Health principles, to understand the interaction of pathogens and the human host, development of diagnostics, treatments, and disease prevention, applied microbiologists can shape global health and wellbeing outcomes.
Viral infections early in pregnancy may disrupt the way the uterine lining prepares for implantation, with effects that can persist throughout pregnancy. In cell, mouse and 3D uterine models, researchers found that inflammation reduced decidualization and was linked to abnormal placental development and smaller fetuses.
Read storyGut bacteria living in industrialised societies appear to be evolving differently from those in non-industrialised populations. Researchers found that strains from industrialised hosts had recently acquired more genes, mostly through horizontal gene transfer, suggesting that modern lifestyles may be reshaping microbial evolution inside us.
A new early-warning method could help detect disease outbreaks even when case data are sparse, delayed or incomplete. By using topological data analysis to capture the underlying shape of epidemic time series, the system remained accurate even when up to half of the surveillance data were missing.
Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) today announced that GSK’s global health vaccine program for a combined invasive nontyphoidal Salmonella and typhoid fever (iNTS‑TCV) has advanced into a Phase 2 clinical trial.
Human cells may possess a previously underappreciated defence against Ebola virus infection. Researchers found that the cell-surface protein CD81 can restrict viral entry and replication, while Ebola appears to use two of its own proteins to counteract this protective mechanism.
The broadly neutralizing antibody VRC01 has been thoroughly vetted as a potential prophylactic that could prevent people from becoming infected with HIV. A new analysis of data shows that the antibody initially provides strong protection, but that some strains of the virus can still cause breakthrough infections after treatment has stopped.
Researchers have described how they advanced an experimental CRISPR approach for sickle cell disease into a blood stem cell therapy that can be manufactured at the scale and quality required for a clinical trial.
Researchers have created the most detailed map yet of how essential genes interact in Mycobacterium tuberculosis. By uncovering nearly 6,500 genetic relationships, the study reveals hidden gene functions and points to new ways of identifying drug targets and more effective antibiotic combinations.
A new toothbrush generates electricity through bristle movement to wage war on plaque-producing pathogens. The invention successfully reduced cavity- and periodontitis-causing bacteria better than regular mechanical brushing in the mouths of 115 volunteers over 3 months.
A researcher has used his AI-supported Sequence Display technology to expand the targeting abilities of CRISPR/Cas9, evolving several variants of a compact Cas9 that could efficiently target stretches of DNA previously inaccessible for editing. The evolved Cas9s were successfully used to edit two genes found in coronary heart disease.
A vaccine candidate developed by scientists at the University of Oxford has been recommended to enter a pivotal Phase 2/3 clinical trial in the Democratic Republic of the Congo (DRC), in a significant step towards tackling Bundibugyo virus, a potentially deadly pathogen for which no vaccine is currently approved.
A sugar naturally found in breast milk may help newborn intestines mature and process bilirubin, the compound that builds up during jaundice. In mice, loss of 3’-sialyllactose disrupted gut development, worsened hyperbilirubinemia and was linked to greater intestinal vulnerability later in life.
A recent study reveals how astroviruses use goblet cells as an escape route from the small intestines to evade host immunity and enhance spread and transmission, presenting a new path for treating pediatric diarrhea.
Researchers are uncovering how cattle genetics and rumen microbes work together to shape methane emissions and feed efficiency. The findings could support new feed additives, probiotics and microbial strategies that reduce emissions while helping cattle extract more energy from their diet.
Even relatively low levels of lead exposure may be linked to a higher risk of strep throat in children. In a study of more than 13,000 children, those with blood lead levels below current public health action thresholds still had substantially higher odds of a strep diagnosis.
Researchers have pioneered a new approach to preventing dangerous bloodstream infections in patients receiving donor stem cell transplants for blood cancers. The first-of-its-kind therapy delivers 16 carefully selected beneficial bacteria designed to restore the microbiome and fight harmful pathogens.
Researchers have developed food-grade, water-resistant microneedles that can vaccinate fish underwater without conventional metal injections. The silk-based patches can remain attached while fish swim, release vaccines at controlled rates and may make it possible to protect much smaller juvenile fish earlier in life.
Whether Staphylococcus aureus can establish itself in our noses also depends on the bacteria living alongside it. These microbial neighbors can either promote or inhibit the pathogen. Key factors include which nutrients the community consumes or releases and the metabolic capabilities of the particular S. aureus strain.
Investigators identified three genes that are essential for biofilm formation in the foodborne bacterial pathogen Salmonella Typhimurium. Their experiments showed that disrupting these genes impaired biofilm structure and adhesion, and also resulted in decreased host colonization and virulence.
Environmental microbiologist Professor James Ebdon, from the University of Brighton, UK, has been named as the winner of the John Snow Public Health Innovation Prize, which recognises outstanding achievements in applied microbiology that deliver measurable improvements in public health and environmental health outcomes.
Members of Applied Microbiology International (AMI) have urged the European Commission to put microbial communities at the heart of environmental risk assessments for genetically modified microorganisms, as part of its response to the EU Biotech Act consultation.
Researchers have built a biocomputer that uses growing bacteria to explore many possible solutions at the same time. By guiding the microbes through microfluidic networks, the system could offer a resource-efficient way to tackle complex problems in areas such as molecular biology, encryption and AI.
Microbiologists have found that an enzyme, not normally associated with microbial activities in the human gut, to have a role in how some bacteria access key nutrients in breast milk.
