| has gloss | eng: The Kinyoun stain is a method of staining acid-fast microorganisms, specifically mycobacterium. The procedure for Kinyoun staining is similar to the Ziehl-Neelsen stain, but does not involve heating the slides being stained.1 The Kinyoun staining method uses carbolfuchsin as a primary stain, followed by decolorization with an acid-alcohol solution and methylene blue as a counterstain. Kinyoun carbolfuschsin has a greater concentration of phenol and basic fuchsin and does not require heating in order to stain properly.1 When viewed under a microscope, a Kinyoun stained slide will show acid-fast organisms as red and nonacid-fast organisms as blue. |
