Figure 5From: Invasiveness as a putative additional virulence mechanism of some atypical Enteropathogenic Escherichia colistrains with different uncommon intimin typesTransmission electron microscopy of polarized and differentiated T84 cells infected via the basolateral side. A) aEPEC 1551-2. B) aEPEC 0621-6. C) prototype tEPEC E2348/69. Monolayers were infected for 6 h (aEPEC) and 3 h (tEPEC). Arrows indicate tight junction and (*) indicates a Transwell membrane pore.Back to article page
