title: Recognition of whole Cryptosporidium oocysts in feces by negative staining and electron microscopy.
abstract: Crytosporidium oocysts in feces were recognizable in the electron microscope when prepared by the negative staining technique used by virologists. Their size, shape, and surface markings were sufficiently characteristic for cryptosporidiosis to be diagnosed by this method if more suitable methods are not available.
