title: Postcystic development of Blastocystis hominis.
abstract: A concentrated suspension of Blastocystis hominis cysts was inoculated into Jones' medium and removed after 24 h for study of their development at the ultrastructural level. The parasite divides in the cyst, and up to three daughter cells can be seen. During this process the cyst wall dissolves, leaving behind thin membranous remnants. Excystation occurs mostly by the emergence of the daughter cells through an aperture in the outer fibrillar coat. Before excystation the vacuolar and the granular stages form and the daughter cells develop their own fibrillar layer.
