The surfaces of Gram-negative bacteria are adorned with versatile nanomachines that include Type IV pili and associated secretion systems. These structures are crucial for a range of functions such as ...

The type III secretion system (T3SS) is a sophisticated molecular apparatus that many Gram‐negative bacterial pathogens deploy to inject effector proteins directly into host cells. This machinery ...

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 ...

With antibiotic-resistant bacteria on the rise, scientists have been searching for ways to shut down the Type IV secretion system (T4SS), a protein complex on the outer envelope of bacterial cells ...

Aquaculture is critical for global food security, yet bacterial diseases remain a persistent challenge that threatens animal welfare and farm profitability.

UPTON, NY — New details of the composition and structure of a needlelike protein complex on the surface of certain bacteria may help scientists develop new strategies to thwart infection. The research ...

You suddenly feel sick -- pathogenic bacteria have managed to colonize and spread in your body! The weapons they use for their invasion are harmful toxins that target the host's defense mechanisms and ...

Life-forms with no brain are capable of some astounding things. It might sound like sci-fi nightmare fuel, but some bacteria can wage kamikaze chemical warfare. Pathogenic bacteria make us sick by ...

Now Niederweis and colleagues at the University of Alabama at Birmingham describe the mechanism of secretion and trafficking of that toxin, TNT, which is the major cytotoxicity factor for the pathogen ...

Bacteria have complex molecular machines that help them drive disease. Scientists can now leverage these machines to treat disease instead. It is nice to deliver drugs where you exactly want them, ...

A study reveals how microscopic bacteria can physically alter your cells and wreak havoc.
