A method and apparatus for producing detectable intestinal parasites. The method includes obtaining an intestinal mucosa sample (e.g. feces) having intestinal parasites, such as Dientamoeba fragilis; and contacting the obtained intestinal mucosa sample with an acridine base compound (e.g. acridine orange and/or acridine yellow, etc.) such that the intestinal parasites become differentially stained and detectable by a human eye when viewed through a fluorescence microscope. The apparatus includes a kit or the like which includes at least one vessel or vial. Preferably, two vials are contained within the kit with one vial having an isotonic salt solution including a salt, sodium chloride, potassium phosphate, etc., and the other vial containing an acridine biological staining compound.
