Actin comet tails consist of branched filaments and parallel bundles. Thin-section EM of L. monocytogenes comet tails in infected PtK cells (A and B), brain cytosol that produces a comet tail consisting of branched filaments and parallel bundles (C), and brain cytosol that produces only branched filaments (D). (E) Comet tails formed initially in brain cytosol that forms branched and bundled filaments, then switched to the same cytosol containing CA. (F) Comet tails formed initially in brain cytosol that forms only branched filaments, then switched to the same cytosol containing CA. Bars: (A, B, E, and F) 1 μm; (C and D) 0.75 μm.
