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).  6, record 2, English, - Gram%20stain

Record number: 2, Textual support number: 1 CONT

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.  7, record 2, English, - Gram%20stain

Método de tinción diferencial de bacterias; los frotis se fijan a la llama, se tiñen con una solución de violeta cristal, se trata con solución de yodo, se lavan, se decoloran y luego se colorean por contraste con safranina O. Los microorganismos grampositivos se tiñen de negro violáceo y los gramnegativos de rosado; es útil en taxonomía e identificación bacteriana y también para indicar diferencias fundamentales en la estructura de la pared celular.  3, record 2, Spanish, - coloraci%C3%B3n%20de%20Gram

leuco bases: Colourless compounds formed by reduction of triphenylmethane dyes. Generally, they are amino or hydroxy derivatives of triphenylmethane. Use of this class name, which is more or less parochial to the technology of dyes, is not endorsed. E.g. (p-Me₂NC₆H₄)₂CHPh, the leuco base of Malachite Green.
