These bacteria induce the assembly of actin-rich tails in the host cell cytoplasm, which enable them to move rapidly. Motile bacteria spread from cell to cell by forming membrane-enclosed protrusions that are engulfed by neighboring cells. (B) Fluorescence micrograph of the bacteria moving in a cell that has been stained to reveal both bacteria and actin filaments. Note the comet-like tail of actin filaments (green) behind each moving bacterium (red). Regions of overlap of red and green fluorescence appear yellow.
