Scanning electron micrograph of a murine macrophage infected with Francisella tularensis strain LVS. Macrophages were dry-fractured by touching the cell surface with cellophane tape after critical point drying to reveal intracellular bacteria. Bacteria (colorized in blue) are located either in the cytosol or within a membrane-bound vacuole.
