NewsResearch collaboration takes ‘one health’ approach to study Chagas disease
Researchers have received more than $4 million from federal and non-governmental organizations to support research on Chagas disease prevalence, diagnostics and treatment to benefit both dogs and humans.

NewsViruses under the super microscope: How influenza viruses communicate with cells
Scientists have characterized a new model of influenza A infection: binding to MHC class II complexes as an alternative receptor and the associated dynamic reorganization of the cell surface.

NewsDisease experts call for reinstatement of CDC’s Healthcare Infection Control Practices Advisory Committee (HICPAC)
The Society for Healthcare Epidemiology of America has called for the reinstatement of CDC’s Healthcare Infection Control Practices Advisory Committee (HICPAC), warning that decades of progress in preventing healthcare-associated infections are under threat.

NewsSpiritual healing sites could be linked to antibiotic-producing microorganisms
A study by AMI member Dr Gerry Quinn highlights the potential of spiritual healing sites as fertile ground for novel antibiotics, particularly from Streptomyces bacteria, known for producing the majority of current antibiotics.

NewsShaken and stirred: why Klebsiella pneumoniae strain 007 poses a deadly threat
A new study has uncovered the secrets of a particular strain of the bacterium Klebsiella pneumoniae, revealing a potentially deadly genetic capacity for both antimicrobial resistance and virulence.

NewsBat virus evolution suggests wildlife trade sparked COVID-19 virus emergence in humans
The ancestor of the virus that causes COVID-19 left its point of origin in Western China or Northern Laos just several years before the disease first emerged in humans up to 2,700 kilometers away in Central China, suggesting the wildlife trade played a role.

NewsBreakthrough discovery uses gut bacteria and AI to diagnose a chronic pain syndrome
Scientists have developed AI technology that can detect patterns in gut bacteria to identify complex regional pain syndrome (CRPS) with remarkable accuracy, potentially transforming how CRPS is diagnosed and treated.
-
NewsSilver nanoparticles produced by fungus could be used to prevent and treat COVID-19
Silver nanoparticles produced by the fungus Trichoderma reesei could become important allies in the prevention and treatment of COVID-19. Tests on hamsters showed that they not only inhibited the infection but also reduced the viral load in the lungs.

NewsFood as medicine: How diet shapes gut microbiome health
New research shows how mice fed a Western-style diet are not able to rebuild a ‘healthy’, diverse gut microbiome following antibiotic treatment. These mice were also more susceptible to infection by pathogens like Salmonella.
-
NewsEngineered soil microbiomes may secure future tomato yields
New findings suggest that manipulating rhizosphere microbiomes could be a sustainable strategy to enhance crop performance in fluctuating environments, supporting the development of resilient agricultural systems.
-
NewsHigh-density screening technique reveals key genes for biotechnology improvements
Scientists used a gene-silencing tool and molecular guides to probe how photosynthetic bacteria adapt to light and temperature changes, finding even partial suppression of certain genes yielded big benefits in modifying the stress response of wild microbes.

NewsLong COVID may cause long-term changes in the heart and lungs and may lead to cardiac and pulmonary diseases
Patients suffering from long COVID may exhibit persistent inflammation in the heart and lungs for up to a year following SARS-CoV-2 infection, potentially placing them at elevated risk for future cardiac and pulmonary conditions.
-
NewsBiological patterns: Stability through protein reservoirs
Biophysicists have figured out how bacteria form robust patterns despite changing environmental conditions and fluctuating protein concentrations.

NewsNew CDC nPEP Guidelines should become ‘part of general medical practice’
Health experts say the updated CDC HIV Non-Occupational Post Exposure Prophylaxis (nPEP) Guidelines should be part of general medical practice, as incorporating them will reduce new HIV infections and improve public health.

NewsFruit and microbes boost biogas production and fermentation
Researchers have reported on a new recipe for improving biogas production from alfalfa. Adding fruit waste and an anaerobic microbe to the mix first leads to co-fermentation, then produces methane.

NewsInvasive rats and rainforest mammals are sharing gut microbes as urban areas grow
As urban development continues to creep further into Earth’s oldest and most diverse rainforests, a study reveals native and invasive small mammals aren’t just adapting to their changing habitats—they may also be sharing their microbes.
-
NewsElectricity-generating bacteria may power future innovations
Scientists have discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen.
-
NewsClinical trial underway for potential Long COVID treatment
A clinical trial is underway to assess the effectiveness and safety of sipavibart, AstraZeneca’s long-acting monoclonal antibody designed to provide protection against Covid-19, as a potential treatment for Long Covid.

NewsDancing plant cells defeat Pseudomonas - and win international competition
The University of Jena, Germany has won the renowned ’Dance your PhD’ competition in the category Biology with its video “Plant Vaccination”. The video visualizes the thesis of Jena doctoral candidate Priya Reddy with dancers and original choreography.

NewsConsumption of ultra-processed foods by children up to one year old favors harmful bacteria in the gut
Analysis of the gut microbiota of more than 700 babies also showed that breastfeeding was a protective factor, mitigating the problem in those who consumed industrialized products. The study underscores the importance of breastfeeding.
