N: 1. Gram (pn): The discoverer of the stain was Hans Christian Joachim Gram, who was born in Denmark in 1853.
– stain (n): 1560s, “act of staining,” from stain (v.). Meaning “a stain mark, discoloration produced by foreign matter” is from 1580s. Meaning “dye used in staining” is from 1758.
2. A method for the differential staining of bacteria by treatment with a watery solution of iodine and the iodide of potassium after staining with a triphenylmethane dye (as crystal violet).
3. The Gram staining method … is one of the most important staining techniques in microbiology. It is almost always the first test performed for the identification of bacteria … The microorganisms that retain the crystal violet-iodine complex appear purple brown under microscopic examination (and) are commonly classified as gram positive … Others that are not stained by crystal violet are referred to as gram negative.
4. The Gram stain is a differential method of staining used to assign bacteria to one of two groups (gram-positive and gram-negative) based on the properties of their cell walls. It is also known as Gram staining or Gram’s method. The procedure is named for the person who developed the technique, Danish bacteriologist Hans Christian Gram.
