FIG. 14.

Interaction of DAEC with epithelial cells. DAEC strain C1845 incubated with HEp-2 cells for 8 h. Note the association of the bacteria with the membrane and the formation of long finger-like projections emanating from the cell. These projections wrap around the bacterium in a phenotype termed “embedding.” Invasion is rarely seen. Reprinted from reference 133 with permission of the publisher.
