Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [ 2 ]
The Schaeffer–Fulton stain is a technique designed to isolate endospores by staining any present endospores green, and any other bacterial bodies red. [1] The primary stain is malachite green , and the counterstain is safranin , which dyes any other bacterial bodies red.
Moeller staining involves the use of a steamed dye reagent in order to increase the stainability of endospores. Carbol fuchsin is the primary stain used in this method. Endospores are stained red, while the counterstain methylene blue stains the vegetative bacteria blue.
The image on the right stains with Lugol's iodine, and identifies a squamous cell carcinoma, which does not pick up the stain. Chromoendoscopy is a medical procedure wherein dyes (often the same stains used in histology ) are instilled into the gastrointestinal tract at the time of visualization with fibre-optic endoscopy .
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.
As with any prescription medication, there are side effects of Wegovy to keep in mind. The most common side effects are gastrointestinal ones, like: Nausea. Vomiting. Heartburn. Diarrhea. Constipation
[1] [2] Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name acid-fast. [ 2 ] The mechanisms of acid-fastness vary by species although the most well-known example is in the genus Mycobacterium , which includes the species ...
However, research does not show whether the binding leads to the harmful side effects from the drug. A sample of the drug Singulair made by Merck & Co. is seen in New York March 9, 2009
