What are A/E lesions, produced by some strains of E. coli?
A) Inflammatory patches caused by the attachment of the bacteria to the intestinal lining by small suction appendages.
B) Intestinal abscesses that form after the bacteria have entered M cells, destroying them and causing bloody diarrhea.
C) Intestinal damage characterized by pedestals that form under bacterial cells as a result of induced actin rearrangement in the intestinal cell.
D) Cytoplasmic extensions induced in intestinal epithelial cells by the injection of superantigens via type III secretion systems.
E) Appendages used by E. coli strains to avoid phagocytosis and enter M cells of the intestinal epithelium.

Quizplus · Accepted Answer

A/E lesions refer to attaching and effacing lesions, which are characterized by the formation of pedestals under bacterial cells due to actin rearrangement in the intestinal cell. This type of lesion is produced by some strains of E. coli and is associated with diarrheal disease.
