Researchers show how opportunistic bacterium defeats competitors

Researchers at the University of São Paulo (USP) in Brazil have described a system present in a species of opportunistic bacterium found in hospital environments that injects a cocktail of toxins into competing bacteria ...

Research team identifies key step in process of Shigella infection

Researchers from the Massachusetts General Hospital (MGH) Division of Infectious Diseases are investigating the mechanism by which several important pathogenic species of bacteria deliver proteins into the cells of the organisms ...

A bacterial ballistic system

Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have determined the structure of a crucial part of one of these ...
