Antibiotic-resistant bacteria is a serious public health threat. Understanding the biology of these bacteria--such as how they synthesise their protective capsules--is essential for developing new ...

In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the ...

Bacteria talk to each other using N-acylhomoserine lactones (AHLs) as quorum sensing (QS) signals. This signaling allows the bacteria to control gene expression of virulence factors and biofilms once ...

Antibiotics are powerful treatments that have saved countless lives over the course of decades. New findings from Scripps ...

A recent Science Immunology study revealed that neonatal gut bacteria produce serotonin and down-regulate monoamine oxidase A (MOA) to limit serotonin breakdown, thereby promoting immune tolerance.
