Gram stain and lactophenol cotton blue stain are used to visualize certain fungal structures that are significant for identification. These include the germinal tube, hyphae, and spores and are especially important in clinical analyses of oral mucosal diseases.The sensitivity of KONCPA is further enhanced by staining with PAS to highlight fungal elements. We combined other fungus-enhancing stains (fluorescent stain and chlorazol black E) with the basic KONC technique to compare sensitivity of methods using these more easily applied stains (KONCFLU and KONCBE). 4,22 and other stains can be added after application of KOH.
