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. It has been considered a standard stain for the detection of spirochetes, and is also used to stain ''Helicobacter pylori'', ''Lawsonia intracellularis'', ''Microsporidia'', and particulates. It is also important for confirmation of ''Bartonella henselae'', a causative organism in cat-scratch disease. Warthin–Starry stains organisms dark brown to black, and the background light golden brown/golden yellow. See also *Dieterle stain The Dieterle stain is a way of marking tissue for microscopic examination. The key reagent of Dieterle stain is silver nitrate. It can stain microbes like ''Treponema pallidum'' in grey or black and background in yellow. It is used to find the org ... References External l ...

Bacteria On Warthin–Starry Stain
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in mutualistic, commensal and parasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
