The bacterial flagellum is one of nature's smallest motors, rotating at up to 60,000 revolutions per minute. To function properly and propel the bacterium, the flagellum requires all of its components to fit together to exacting ...

Precut salad may encourage growth of Salmonella

A new study from the University of Leicester shows that small amounts of damage to salad leaves in bagged salads encourage the presence of Salmonella enterica. Juices released from damaged leaves also enhance the pathogen's ...

Discovery of mechanism that enables bacteria to elude antibiotics

Researchers from UAB describe for the first time, in a work published in PLOS ONE, a model of the behaviour of a bacterial colony that shows how it protects itself against toxic substances like antibiotics during the colonisation ...
