Gram stain vs acid-fast stain
Did you know?
WebAcid-fastness is a physical property of certain bacterial and eukaryotic cells, as well as some sub-cellular structures, specifically their resistance to decolorization by acids during laboratory staining procedures. Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many … WebAn acid-fast stain is able to differentiate two types of gram-positive cells: those that have waxy mycolic acids in their cell walls, and those that do not. Two different methods for …
WebFeb 13, 2024 · The main difference between Gram stain and acid fast stain is that Gram stain helps differentiate bacteria with different cell wall types, while acid fast stain helps differentiate Gram positive bacteria with waxy mycolic acids in their cell walls . WebJun 1, 2024 · Acid-fast bacteria are gram-positive in terms of structure because they contain peptidoglycan in the cell wall. However, they stain poorly with Gram stain …
WebWe used Brilliant Green- this is used for the final reagent to stain previously decolorized cells. As only non-acid-fast cells undergo decolorization, they may now absorb the counterstain and take on it green color, while acid-fast cells retain the red of the primary stain Organisms used for the acid-fast WebAdd 20% sulphuric acid and leave it for 1-2 minutes.
