2. Gram stain - Wikipedia

   en.wikipedia.org/wiki/Gram_stain

   Gram stain (Gram staining or Gram's method), is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. It may also be used to diagnose a fungal infection. [1] The name comes from the Danish bacteriologist Hans Christian Gram, who developed the technique in 1884. [2]

3. Calcofluor-white - Wikipedia

   The study also showed that no special techniques were needed to make the staining effective. The dye also does not interfere with PAS or Gram staining. For cytology, Pap-CFW gave a positive response 50 out of 135 times, and for histopathology, it gave a positive response 43 out of 135 for just the CFW stain. The study showed that the staining ...

4. Gram-positive bacteria - Wikipedia

   en.wikipedia.org/wiki/Gram-positive_bacteria

   In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. The Gram stain is used by microbiologists to place bacteria into two main categories, Gram-positive (+) and Gram ...

5. Crystal violet - Wikipedia

   en.wikipedia.org/wiki/Crystal_violet

   The stain proved popular and in 1884 was used by Hans Christian Gram to stain bacteria. He credited Paul Ehrlich for the aniline-gentian violet mixture. [ 32 ] Grübler's gentian violet was probably very similar, if not identical, to Lauth's methyl violet, which had been used as a stain by Victor André Cornil in 1875.

6. Deinococcus - Wikipedia

   en.wikipedia.org/wiki/Deinococcus

   These bacteria have thick cell walls that give them Gram-positive stains, but they also include a second membrane and are therefore closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation.

7. Gimenez stain - Wikipedia

   en.wikipedia.org/wiki/Gimenez_stain

   Although largely superseded by techniques like Giemsa staining, the Gimenez technique may be valuable for detecting certain slow-growing or fastidious bacteria. Basic fuchsin stain in aqueous solution with phenol and ethanol colours many bacteria (both gram positive and Gram negative) red, magenta, or pink.
