In
bacteriology, the Gram staining allows a fast differentiation of
bacteria in Gram-positive and Gram-negative. The mureine structure of
the bacteria walls is the basis of the color affinity. Bacteria will be
stained with Gram's crystal violet solution - an aniline dye - in the
first step. After the treatment with Gram's iod solution (Lugol’s
solution), a dye-iod complex will form. During the decolorizing step,
this complex stays in the multilayer mureine structures of the
Gram-positive bacteria and they will appear blue. Gram-negative bacteria
have a monolayer mureine structure only, the dye-iod complex does not
stay bound to the cellwall, they will be decolorized . Gram-negative
bacteria will be counterstained by Gram's safranin solution and appear
orange. A 500 mL PE-bottle of Gram's Lugol's solution is sufficient for
staining up to 250 slides. Lugol’s solution is also a part of the
Gram-color stain set. It is an IVD & CE product.
