University of Toronto researchers have expanded our understanding of bacterial immunity with the discovery of a new protein ...

Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria ...

Biologists from ETH Zurich have discovered speargun- like molecular injection systems in two types of bacteria and have described their structure for the first time. The special nanomachines are used ...

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...
