title: Variation in the cyst morphology of Blastocystis hominis.
abstract: Two types of Blastocystis hominis cyst are passed in human feces, one with an outer fibrillar coat and the other without it. The outer fibrillar coat is shed as the cyst matures, but another fibrillar coat forms that is closely attached to the cyst wall and is clearly visible at high magnification in the electron microscope. The internal structure of the two cyst form is similar.
