Cryo-electron microscopic reconstruction of the antigen binding region of a human antibody (yellow) to the needle tip complex (blue) of the type III secretion system of Pseudomonas aeruginosa.

UMass Amherst biochemists are mapping the molecular structure of a needle-like tool used by bacteria to invade human and mammalian cells to cause such diseases as plague and dysentery. Of particular ...

Scientists have discovered that erucamide, a plant-produced fatty acid amide, disrupts the function of the bacterial injectosome—a syringe-like nanomachine that some pathogenic bacteria use to help ...
