Complications• Hemolytic Uremic Syndrome (HUS): a severe, life-

threatening complication of an E. coli infection – E. coli secretes toxins – Cells have toxin receptor sites that allow the toxins to get in

and kill the cell– Kidney, pancreas, and brain have more than other organs

• Thrombotic Thrombocytopenic Purpura (TTP) syndrome: low platelet & RBC

– Endothelial cell damage– Cascade of biochemical events– Blood clots-block the terminal arterioles and capillaries of most of

the major body organs:• Heart, brain, kidneys, pancreas and adrenals.
