NewsScientists find new way to disarm antibiotic-resistant bacteria and restore healing in chronic wounds
Scientists have discovered a new way that could speed up the healing of chronic wounds infected by antibiotic-resistant bacteria. The study shows how a common bacterium, Enterococcus faecalis (E. faecalis), actively prevents wound healing.

NewsBacterial energy model reveals how antimicrobial resistance (AMR) spreads in environment
Researchers analyzed how bacteria in aquatic environments distribute energy across diverse functions such as growth, biofilm formation, conjugative transfer of antimicrobial resistance genes and heavy‑metal tolerance, to clarify bacterial energy investment strategies.

NewsA CRISPR fingerprint of pathogenic Candida auris fungi
Precision diagnostic platform integrating CRISPR and single molecule technology with AI enables rapid and accurate detection of drug-resistant Candida auris pathogens.

NewsShould younger and older people receive different treatments for the same infection?
Scientists find the mechanisms young mice use to fight sepsis become disadvantageous in older age, suggesting age-specific treatments may be necessary in ongoing antibiotic resistance crisis.

FeaturesUnlocking the secrets of phages: DNA modification discoveries offer new weapons against antimicrobial resistance
Bacteria and their viral predator bacteriophages (phages) have coevolved for billions of years and are engaged in an endless arms race against each other. DNA modifications are among the most widespread defenses to block bacterial RM and CRISPR-Cas systems.

NewsResearch reveals hidden diversity of E. coli driving diabetic foot infections
New research has shed light on the diversity and characteristics of E. coli strains that drive diabetic foot infections, providing the first comprehensive genomic characterisation of E. coli strains isolated directly from diabetic foot ulcers across multiple continents.

NewsFirst extensive study into marsupial gut microbiomes reveals new microbial species and antimicrobial resistance
New research provides the first metagenomic data for 13 marsupial species , including the red kangaroo and the common brushtail possum. They revealed that host family, animal location, and diet all contributed towards variance between different microbiomes.

NewsA protein found in the GI tract can neutralize many bacteria
The mucosal surfaces that line the body are embedded with defensive molecules that help keep microbes from causing inflammation and infections. One of these molecules, intelectin-2, has broad-spectrum antimicrobial activity against bacteria found in the GI tract.

NewsEarthworms turn manure into a powerful tool against antibiotic resistance
Earthworms could become unexpected allies in the global fight against antibiotic resistance, by helping farmers turn manure into safer, high-value organic fertilizer through vermicomposting. Researchers report it can remove antibiotic resistance genes far more consistently than conventional composting.

NewsBiodegradable and conventional plastics shape very different antibiotic resistance risks in river microbiomes
Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river.
-
NewsMelting glaciers may release hidden antibiotic resistance into vital water sources
Researchers report that glaciers act as long-term reservoirs of antibiotic resistance genes. Once released by glacier melt, these genes can enter rivers, lakes, and ecosystems that supply drinking water and support wildlife in polar and high-altitude regions.
-
NewsSub-lethal water disinfection may accelerate the spread of antibiotic resistance
A new study reveals that environmental stressors do not merely kill bacteria; they can also prime surviving cells to take up resistance genes more efficiently, raising concerns about how antibiotic-resistant bacteria may spread in aquatic environments.

NewsViruses in wastewater: Silent drivers of pollution removal and antibiotic resistance
New findings suggest that current monitoring strategies, which rely heavily on bacterial indicators alone, may miss critical viral-driven risks and opportunities for safer wastewater reuse.

NewsNew clinical standards strengthen antimicrobial stewardship in tuberculosis care
An international panel of experts from 32 countries has presented specific antimicrobial stewardship standards for TB care for the first time.

NewsHow the parasite that ‘gave up sex’ found more hosts – and why its victory won’t last
A study has revealed a genetic shortcut that may help Giardia duodenalis and many other parasites jump to new hosts at the cost of long-term survival. The findings may also help explain how parasites evolve drug resistance.

NewsMicrobes that break down antibiotics help protect ecosystems under drug pollution
A new study shows that certain microbes can act as community protectors by breaking down antibiotics and stabilizing entire microbial ecosystems, offering a new way to rethink environmental risk assessment and pollution management.

NewsUrban wild bees act as “microbial sensors” of city health
A new study shows that the guts of urban-dwelling wild bees contain detailed microbial signatures that reflect both bee health and the quality of the surrounding environment, offering a powerful new tool for monitoring ecological well-being in cities.

NewsResearchers use robotics to find potential new antibiotic among hundreds of metal complexes
Researchers have used a cutting-edge robotic system capable of synthesising hundreds of metal complexes to develop a possible antibiotic candidate - offering fresh hope in the global fight against drug-resistant infections.

NewsAntibiotic resistance is ancient, ecological, and deeply connected to human activity, new review shows
Antibiotic resistance genes are often portrayed as a modern medical problem driven by the overuse of antibiotics in hospitals and farms. A new comprehensive review published in Biocontaminant reveals a much deeper and more complex story. Antibiotic resistance is an ancient feature of microbial life, shaped by millions of years ...

NewsEnvironmental traces of antibiotics found to boost gene transfer among bacteria
Using models of vertical inheritance and horizontal transfer, researchers have found that low doses of tetracycline, ampicillin, kanamycin, and streptomycin stabilize resistance and promote gene transfer across species.
