Microscope/Schematic (IMAGE) Princeton University Caption Princeton University researchers have identified the protein that allows <i>Vibrio cholerae</i> -- the bacteria behind the life-threatening disease cholera -- to morph into a corkscrew shape that allows them to more effectively penetrate their victims' intestines. In the image above, red-stained V. cholerae bacteria (right) exhibit the shape-changing protein (stained green), which the researchers named CrvA. The schematic models (left) highlight the bacteria's twisted shape during infection.
