  2. Giemsa stain - Wikipedia

    en.wikipedia.org/wiki/Giemsa_stain

    It is also used to stain Wolbachia cells in host tissue. [3] Giemsa stain is a classic blood film stain for peripheral blood smears and bone marrow specimens. Erythrocytes stain pink, platelets show a light pale pink, lymphocyte cytoplasm stains sky blue, monocyte cytoplasm stains pale blue, and leukocyte nuclear chromatin stains magenta.

  3. Romanowsky stain - Wikipedia

    en.wikipedia.org/wiki/Romanowsky_stain

    Blood film stained with Giemsa showing Plasmodium (center of image), the parasite that causes malaria infections.. In 1891 Romanowsky [8] [9] [10] developed a stain using a mixture of eosin (typically eosin Y) and aged solutions of methylene blue that formed hues unattributable to the staining components alone: distinctive shades of purple in the chromatin of the cell nucleus and within ...

  4. Blood smear - Wikipedia

    en.wikipedia.org/wiki/Blood_smear

    The fixative is essential for good staining and presentation of cellular detail. After fixation, the slide is stained to distinguish the cells from each other. [citation needed] Routine analysis of blood in medical laboratories is usually performed on blood films stained with Romanowsky stains such as Wright's stain, Giemsa stain, or Diff-Quik ...

  5. Diff-Quik - Wikipedia

    en.wikipedia.org/wiki/Diff-Quik

    [1] [2] [3] The Diff-Quik procedure is based on a modification of the Wright-Giemsa stain pioneered by Harleco in the 1970s, [1] and has advantages over the routine Wright-Giemsa staining technique in that it reduces the 4-minute process into a much shorter operation and allows for selective increased eosinophilic or basophilic staining ...

  6. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue .

  7. Gustav Giemsa - Wikipedia

    en.wikipedia.org/wiki/Gustav_Giemsa

    In 1904 Giemsa published an essay on the staining procedure for flagellates, blood cells, and bacteria. Giemsa improved the Romanowsky stain (Eosin Y and Methylene Blue) by stabilizing this dye solution with glycerol. [2] This allowed for reproducible staining of cells for microscopy purposes.

  8. Gimenez stain - Wikipedia

    en.wikipedia.org/wiki/Gimenez_stain

    The Gimenez staining technique uses biological stains to detect and identify bacterial infections in tissue samples. Although largely superseded by techniques like Giemsa staining , the Gimenez technique may be valuable for detecting certain slow-growing or fastidious bacteria.

  9. Granuloma inguinale - Wikipedia

    en.wikipedia.org/wiki/Granuloma_inguinale

    Tissue biopsy and Wright-Giemsa stain are used to aid in the diagnosis. The presence of Donovan bodies in the tissue sample confirms donovanosis. Donovan bodies are rod-shaped, oval organisms that can be seen in the cytoplasm of mononuclear phagocytes or histiocytes in tissue samples from patients with granuloma inguinale. [9]
