Fever, leukopenia, DIC, and hypotension caused by members of the Enterobacteriaceae family are most strongly associated with which structure?
a. The lipopolysaccharide (LPS) of gram-negative cell walls consists of a complex lipid, lipid A, to which is attached a polysaccharide made up of a core and a terminal series of repeat carbohydrate units.
b. LPS is attached to the outer membrane by hydrophobic bonds and is required for the function of many outer membrane proteins.
c. All the toxicity resides in the lipid A component.
d. Endotoxin (lipid A) can activate complement, resulting in inflammation and the clinical features referred to in the question.
