Histological examination of immortalized STEC line and primary STECs cultured under Ali conditions. At D14, the cultures were fixed with 4% polyoxymethylene, then followed by histological sectioning and H&E staining. Ciliogenesis was assessed by counting the number of ciliated cells per randomly chosen microscope field (400 × magnification). Data are given as the mean +/− SD of three microscope fields per culture and three independent cultures (n = 9). (*P < 0.05, **P < 0.01)
