How can antibiotics upset the barrier function of intestinal epithelia? Give a specific example
What will be an ideal response?
Antibiotics attack the microbiological barriers of intestinal epithelia. The normal microbiota sensitive to the antibiotics are killed off and the intestine can then be recolonized and overgrown by microorganisms that in normal circumstances are present in very small numbers and thus do not cause a problem. An example is a condition called pseudomembranous colitis caused by the overgrowth of Clostridium difficile. A membrane-like substance is produced in the large intestine, causing an obstruction that can block intestinal flow and usually requires surgical removal.
