Giemsa stained Trypanosoma parasites (Chagas disease pathogen) Whirling disease section stained with Giemsa stain. Giemsa stain (/ ˈ ɡ iː m z ə /), named after German chemist and bacteriologist Gustav Giemsa, is a nucleic acid stain used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
[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 ...
Pappenheimer bodies (Peripheral Blood / May-Grünwald Giemsa and Prussian blue stain) Pappenheimer bodies are abnormal basophilic granules of iron found inside red blood cells on routine blood stain. [1] They are a type of inclusion body composed of ferritin aggregates, or mitochondria or phagosomes containing aggregated ferritin. They appear ...
Polychromatic red blood cells appear bluish-gray on the blood smear. Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation ( poly - refers to many , and -chromasia means color .)
Modern complete blood count analyzers can provide an automated white blood cell differential, but they have a limited ability to differentiate immature and abnormal cells, so manual examination of the blood smear is frequently indicated. [5] [6] Blood smear examination is the preferred diagnostic method for certain parasitic infections, such as ...
The papanicolaou stain is now used in place of cytological staining in all organ types due to its increase in morphological quality, decreased staining time, and decreased cost. It is frequently used to stain Pap smear specimens. [11] It uses a combination of haematoxylin, Orange G, eosin Y, Light Green SF yellowish, and sometimes Bismarck Brown Y.
