Fig. 2.

Serial thin-section imaging by TEM of N. gonorrhoeae-infected epithelial cells. A431 cells were mock-infected with medium (a), or infected with wt MS11 (b) or MS11pilT (c) for 3 h. Successive serial thin-section (70 nm) images from each sample are shown from left to right. Arrowheads highlight short microvilli in uninfected and pilT-infected samples, and elongated microvilli of wt-infected samples. The rightmost panels in each row are enlarged images from the boxed region in the adjacent image. Bars, 500 nm.
