  2. Ziehl–Neelsen stain - Wikipedia

    en.wikipedia.org/wiki/Ziehl–Neelsen_stain

    These acids resist staining by ordinary methods such as a Gram stain. [9] It can also be used to stain a few other bacteria, such as Nocardia. The reagents used for Ziehl–Neelsen staining are carbol fuchsin, acid alcohol, and methylene blue. Acid-fast bacilli are bright red after staining. [citation needed]

    en.wikipedia.org/wiki/Staining

    A simple staining method for bacteria that is usually successful, even when the positive staining methods fail, is to use a negative stain. This can be achieved by smearing the sample onto the slide and then applying nigrosin (a black synthetic dye) or India ink (an aqueous suspension of carbon particles).

    Gastric signet ring cell carcinoma histopathology, PAS stain Esophageal candidiasis, PAS stain Liver in glycogen storage disease, PAS stain. PAS staining is mainly used for staining structures containing a high proportion of carbohydrate macromolecules (glycogen, glycoprotein, proteoglycans), typically found in e.g. connective tissues, mucus, the glycocalyx, and basal laminae.

    en.wikipedia.org/wiki/Warthin–Starry_stain

    The Warthin–Starry stain (WS) is a silver nitrate-based staining method (a silver stain) used in histology. It was first introduced in 1920 by American pathologists Aldred Scott Warthin (1866–1931) and Allen Chronister Starry (1890–1973), for the detection of spirochetes .

    en.wikipedia.org/wiki/Grocott's_methenamine...

    In pathology, the Grocott–Gömöri's methenamine silver stain, abbreviated GMS, is a popular staining method in histology. The stain was originally named after György Gömöri, the Hungarian physician who developed the stain. It is used widely as a screen for fungal organisms. It is particularly useful in staining carbohydrates.

  7. 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]

  8. Golgi's method - Wikipedia

    en.wikipedia.org/wiki/Golgi's_method

    Golgi's method is a silver staining technique that is used to visualize nervous tissue under light microscopy. The method was discovered by Camillo Golgi , an Italian physician and scientist , who published the first picture made with the technique in 1873. [ 1 ]

  9. Trichrome staining - Wikipedia

    en.wikipedia.org/wiki/Trichrome_staining

    In "one-step" methods, all the dyes—with or without a polyacid—are combined in a single solution. One of the oldest single-step approaches to trichrome staining is van Gieson's method, which stains muscle and cytoplasm yellow, and collagen red. Another is the Gömöri trichrome stain, which closely mimics Masson's trichrome. In "yellowsolve ...
