An international collaboration has achieved an important breakthrough in understanding the genetic mechanisms that allow bacteria to build resistance to drugs.

Researchers made a “huge breakthrough” when they did an experiment “purely out of curiosity” which solves “a decades-long ...

A global team has made a significant advance in understanding how bacterial plasmids contribute to antibiotic resistance.

Fu and colleagues used Vibrio cholerae bacteria as a model for studying the plasmid defense system known as DdmDE, consisting of proteins called DdmD and DdmE, using cryo-electron microscopy to ...

Outer membrane protein TraT protects bacteria from secondary F plasmid conjugation. Here, the authors report cryo-EM structure of decameric cork-like TraT and its evolutionary history as a ...
