What is the order of reagents used in the gram stain?
The stains are applied to a smear of bacteria on a microscope slide in the following order: crystal violet, Gram's iodine, decolorizing agent, and safraninsafraninSafranin (also Safranin O or basic red 2) is a biological stain used in histology and cytology. Safranin is used as a counterstain in some staining protocols, colouring cell nuclei red. This is the classic counterstain in both Gram stains and endospore staining.https://en.wikipedia.org › wiki › SafraninSafranin – Wikipedia.

They may either be motile or nonmotile. If motile, they have a flagellum. A typical flagellum consists of a basal body, filament, and hook.https://en.wikipedia.org › wiki › EubacteriumEubacterium – Wikipedia bacteria after the application of each reagent is presented in Table I.
