NewsMolecular clock analysis shows bacteria used oxygen long before widespread photosynthesis
Researchers have constructed a detailed timeline for bacterial evolution and oxygen adaptation. Their findings suggest some bacteria could use trace oxygen long before evolving the ability to produce it through photosynthesis.

NewsNew vaccine concept tackles harmful bacteria in the intestine
Scientists have demonstrated how highly effective oral vaccinations can be formulated against intestinal pathogens by not only administering the vaccine but also combining it with harmless bacteria that compete with the pathogenic microbes for food and therefore starve them out.
-
NewsAntibiotic resistance among key bacterial species plateaus over time
Scientists studying eight key bacterial species found that while antibiotic resistance initially rises in response to antibiotic use, it does not rise indefinitely. Instead, resistance rates reached an equilibrium over the 20-year period in most species.
-
NewsSome gut bacteria could make certain drugs less effective
Researchers discovered that gut bacteria can metabolize oral administered drugs that target G protein-coupled receptor (GPCR) and potentially other chemicals and food compounds, leading to impacts on the effectiveness of medication to patients.

NewsNew antibiotic for multidrug resistant superbug triggers suicide mechanism
Researchers have discovered a new class of antibiotic that selectively targets Neisseria gonorrhoeae, the bacterium that causes gonorrhoea.
-
NewsMulti-resistance in bacteria predicted by AI model
An AI model can predict whether bacteria will become antibiotic-resistant. The study shows that antibiotic resistance is more easily transmitted between genetically similar bacteria and mainly occurs in wastewater treatment plants and inside the human body.
-
NewsPrecision medicine could be possible in the fight against antibiotic resistance
The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for certain antibiotic-resistant infections, such as urinary tract infections.

NewsSurgical fixation for infected sites in pyogenic spondylodiscitis inhibits bone destruction and promotes healing
Pyogenic spondylodiscitis is caused by bacterial infections of the spine and intervertebral discs. Researchers investigated how osterior fixation, in which the normal spine is fixed with pedicle screws and rods to stabilize the infected site, suppresses infection.

NewsHidden virus harboured by fruit flies may influence experimental accuracy
A new study suggests the presence of Nora virus in laboratory strains of Drosophila fruit flies influences their resilience to stress and bacterial infection and can confound experimental studies of ageing.

NewsBacteria deployed to fix cracks in space bricks
Researchers have developed a bacteria-based technique to repair bricks that can be used to build lunar habitats, if they get damaged in the moon’s harsh environment.

NewsUrbanization reshapes soil microbes: Bacteria adapt, fungi resist
A groundbreaking study reveals that urban environments favor bacterial generalists, which adapt to diverse conditions, whereas fungi maintain specialized ecological roles. Despite these divergent responses, the functional overlap between bacteria and fungi ensures ecosystem resilience.
-
NewsMicroalgae and bacteria team up to convert CO2 into useful products
Most methods of genetically modifying the bacterium Escherichia coli and other microbes to convert carbon dioxide into useful biological products require additional carbon sources. A new study overcomes this limitation by combining the photosynthetic finesse of a single-celled algae with the production capabilities of the bacteria E. coli.

NewsChemical radar enables bacteria to detect and kill predators
Researchers have identified a previously unknown defense mechanism of Pseudomonas syringae. They were able to show how the bacterium uses a chemical radar to recognize and eliminate hostile amoebae.
-
NewsNew agent inhibits Staphylococcus aureus toxin – hope for pneumonia patients
Researchers have developed a miniaturized test system that allowed them to screen over 180,000 compounds for their ability to block the effect of the key virulence factor α-hemolysin in S aureus. Drug candidates from the quinoxalinedione class, in particular the compound H052, proved to be highly effective, both in cell culture and in animal models.

NewsA new model is validated to predict the growth of listeria in artisanal fresh cheeses
Researchers have developed a new mathematical model capable of predicting the growth of listeriosis within food, making it possible to estimate the shelf lives of food products under different foreseeable storage conditions.
-
NewsNew Cedars-Sinai study shows how specialized diet can improve gut disorders
A new study examined whether a specialized diet could improve symptoms of gastrointestinal disorders linked to an imbalance in gut microbiota. The research tested the elemental diet’s effectiveness and explored whether improving its unappealing taste— a major barrier—could help patients adhere to the diet’s stringent protocol.
-
NewsA borrowed bacterial gene allowed some marine diatoms to live on a seaweed diet
A group of diatom species belonging to the Nitzschia genus gave up on photosynthesis and now get their carbon straight from their environment, thanks to a bacterial gene picked up by an ancestor, a new study shows.
-
NewsMany TB cases may have gone undetected in prisons in Europe and the Americas during COVID-19
A new study found that reported diagnoses for tuberculosis were consistently lower than expected throughout the pandemic, even though incarceration rates remained largely consistent.

NewsDeadly antibiotic-resistant ‘superbug’ bacteria spreading in Malaysian hospital
A virulent strain of antibiotic-resistant ‘superbug’ that causes severe disease has been found circulating in a Malaysian hospital - posing significant challenges to global public health, a new study reveals.

Careers Revolutionizing water safety: a rapid solution for detecting Shiga toxin-producing Escherichia coli contamination
Contaminated water is particularly dangerous in rural areas where private groundwater wells supply drinking water to households - but AMI One Health Advisory Group member Dr Zina Alfahl reveals a low-cost, simple way to check for STEC.
