Gram-Hücker staining is based on the same principle than the Gram-Nicolle staining. The structure of the bacterial walls and their permeability to alcohol help differentiate the Gram-negative bacteria from the Gram-positive ones. In this technique, Carbolic Gentian Violet is replaced by Crystal Violet Oxalate (that does not require filtration) and Ziehl-Carbolic Fuchsin by Safranin.
