Clusters of bacteria (arrow) shown on 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 .
[7] [8] Microbiologic agents, such as bacteria and fungi, also appear more easily in Diff-Quik. [3] This is useful for the detection of for example Helicobacter pylori from gastric and pyloric specimens. [5] Due to its short staining time, Diff-Quik stain is often used for initial screening of cytopathology specimens.
[13] [14] Although the data varies between different countries, overall about 1% to 3% of people infected with Helicobacter pylori develop gastric cancer in their lifetime compared to 0.13% of individuals who have had no H. pylori infection. [55] [32] H. pylori-induced gastric cancer is the third highest cause of worldwide cancer mortality as ...
Helicobacter heilmannii s.s. (H. heilmannii s.s.) is a species within the Helicobacter genus of Gram negative bacteria. [1] Helicobacter pylori (H. pylori) is by far the best known Helicobacter species primarily because humans infected with it may develop gastrointestinal tract diseases such as stomach inflammation, stomach ulcers, duodenal ulcers, stomach cancers of the non-lymphoma type, and ...
It is also used to find Helicobacter pylori. [1] Intestinal mucins also take up the stain although not as strongly as Campylobacter-like organisms. [2] Cresyl violet is used to stain Heinz bodies in red blood corpuscles or for staining of the neurons in the brain and spinal cord. It is used to demonstrate the Nissl substance in the neurons and ...
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.
Helicobacter heilmannii sensu lato (i.e. H. heilmanni s.l.) is a grouping of non-H. pylori Helicobacter species that take as part of their definition a similarity to H. pylori in being associated with the development of stomach inflammation, stomach ulcers, [11] duodenum ulcers, [12] stomach cancers that are not lymphomas, and extranodal ...
Carbol fuchsin, carbol-fuchsin, carbolfuchsin, or Castellani's paint is a mixture of phenol and basic fuchsin that is used in bacterial staining procedures. It is commonly used in the staining of mycobacteria because it has an affinity for the mycolic acids found in their cell membranes. It is a component of Ziehl–Neelsen stain, a ...
