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 ...

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.
