Scientists uncover protein switch that turns on leptospirosis virulence

During infection, pathogens must adapt quickly to the conditions to thrive inside the body. A research team at the University of Basel, Switzerland, has uncovered how a key protein switches on the machinery that enables Leptospira pathogens to survive and cause disease.

Bacterial vesicles emerge as powerful tools against antibiotic resistance

Antibiotic resistance is making bacterial infections harder to treat, demanding new therapeutic strategies. A new review highlights bacterial extracellular vesicles (BEVs) as promising nanoscale tools that can kill pathogens, block infection, enhance vaccines, and deliver drugs.

Molecular gatekeepers in bacteria prevent the spread of antibiotic resistance

A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads.

Children with multiple chronic conditions show unique antibiotic exposure patterns

A new study from Boston Children's Hospital found that annual prescription rates increased non-linearly as children's underlying level of medical complexity increased. Frequent antibiotic use has associated risks, including increased likelihood of antibiotic-related complications (e.g., C. difficile) as well as the development of antibiotic resistance. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.
