title: [Entamoeba histolytica stained with Warthin-Starry stain].
abstract: The Warthin-Starry stain have been used for coloring a different microorganism like spirochetas, Donovan bodies and Campylobacter and also melanin granules demonstration in soft tissues tumors. We started using the stain, as we know it, in order to stain the Histolytica amebas. We observed parasite stained black and brown as well as a good differentiation between endoplasm and ectoplasm where granular appearance, bacterial remnants and red cells were apparent. The stain was also usefull in differentiating amebas from histiocytes. We advice its use in amebiasis since is inexpensive and easy to do.
