For eosinnigrosin staining, an aliquot (5 L) of diluted semen was mixed with an equal volume of eosinnigrosin solution. On microscopic observation, cell organelles, bacteria, and parasites are distinguished based on their morphology and color; Wright-Giemsas stain is commonly used to demonstrate the cellular elements in peripheral blood and bone marrow smears.
