Abstract
Potassium dichromate and formalin reduced the viability of Cryptospori dium parvum oocysts as assessed by inclusion or exclusion of 4',6-diam idino-2-phenylindole (DAPI) and propidium iodide (PI) and excystation. Some formalin-treated oocysts containing dead sporozoites excluded PI ; that this fluorogenic assay relies not solely upon exclusion of PI b ut also upon highlighting of sporozoite nuclei by DAPI is reiterated.
