shigella is a nonmotile microorganism that appears to utilize host cell microfilaments to generate intra- as well as intercellular movements , since this movement was inhibited by cytochalasin d and involvement of f-actin was demonstrated by direct labeling of infected cells with the specific dye n- ( 7-nitrobenz-2-oxa-1,3-diazol-4-yl ) phallacidin .
