Microscope Shot (IMAGE) Princeton University Caption In experiments, the researchers found that curved <i>V. cholerae</i> cells (left column) could more easily move through a thick gel. Straight rod-shaped <i>V. cholerae</i> that had the protein CrvA suppressed (right column) could not infect a host as efficiently. The researchers elongated the wild-type and CrvA-suppressed cells (bottom row) to accentuate the difference in shape the protein produces.
