Gram-negative bacteria will stain what color?

Question

Quizplus · Accepted Answer

Gram-negative cells have a thin layer of PG with a lipid layer surrounding it, producing pinkish-red stained cells when stained with Gram's stain. Gram-positive cells have a thick layer of PG with no lipid layer surrounding them, which produces deep blue/violet stained cells when stained with Gram's stain. Acid-fast cells have a thin layer of PG surrounded by a thick layer of waxlike lipids. Acid-fast bacteria do not stain well with Gram's stain; acid-fast-positive bacteria (AFB) stain pink with the acid-fast stain.
