This classical staining method allows a quick differentiation of gram-positive and gram-negative bacteria. Subsequently a specific treatment with antibiotics is possible.
In the first step bacteria are stained by Carbol gentianaviolet and Lugol solution. Afterwards gram-negative bacteria are decolourised by Gram’s decolourising solution. In the last step these bacteria are counterstained by Carbol fuchsine solution.
Result: Gram-positive bacteria appear blue, gram-negative bacteria red.
