LtxA mediates collapse of microvilli on Jn.9 target cells. The samples were prepared for conventional scanning electron microscopy of an untreated control (Fig. 2A_1–3) and experimental groups after 30 min (Fig. 2B_1–3) and 3 h (Fig. 2C_1–3) of incubation with LtxA (1 × 10⁻⁹ M). Images are representative of the unique phenotypes observed within each group in three independent experiments. All images were acquired at × 6000 and bars equal 2.5 µm. MV, microvilli; D, depression; C, cavity.
