Case of the Week 478

This week's case was generously donated by our long time contributor, Florida Fan. The following were noted in the stool of a apparently healthy man with no known travel history. The eosin wet mounts were photographed using the 40x objective, while the trichrome-stained slides were photographed using 100x. We don't make eosin saline mounts in my laboratory anymore; I had forgotten how pretty they can be.





Identification?

    Entamoeba coli cysts and trophozoits. Thick walled cysts.
    Mature cysts having more than 4 nuclei with peripheral chromatine and a central karyosome.
    Trophozoit’s karyosome stains blurry in trichrome stain.

    I think they are trophozoites and cysts of Entamoeba coli too.
