Scanning electron microscopy of the surface coat of Blastocystis hominis

Document Type



Pathology and Laboratory Medicine


Scanning electron microscopy of Blastocystis hominis showed that its outer coat has a fibrillar structure and individual fibrils may extend up to 5 microm from the periphery of the parasite. The surface coat remains intact during cell division. Bacteria are often seen adhering to it, but for the first time a trophozoite of Chilomastix mesnili was also seen in this position. It is postulated that breakdown of attached organisms may provide nutrients for Blastocystis.
