Catalase in microsporidian spores before and during discharge.

From: The Biological Bulletin | Date: October 1, 2003| Author: | Copyright information

The noted parasitologist Horace W. Stankard characterized microsporidians as among the most widespread of parasites, possessing significant survival adaptations, a consequence of their longterm host associations (1). One of the more obvious adaptations within this group is the extrusion apparatus of the infective spore stage. This apparatus consists of an aperture, a polaroplast membrane, a polar filament, and a posterior vacuole, or swelling organelle. The energy source for the firing of this apparatus is thought to reside in the posterior vacuole (2). In an earlier report (3), ...
