A remarkable survival adaptation of microsporidians is the spore extrusion apparatus (EXA), which is equipped to explosively discharge a tube through which the infective sporoplasm is sent into a host cell. The EXA consists of a membrane-associated aperture, polaroplast, polar filament protein, and a posterior vacuole. When the spore activates, the EXA discharges a long, fine tube by an apparent eversion process. When the tube is fully formed, the sporoplasm moves down the tube and ...

Catalase in microsporidian spores before and during discharge.
The Biological Bulletin ; 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
Protein-membrane interaction is essential to normal assembly of the microsporidian spore invasion tube.
The Biological Bulletin ; Introduction Microsporidians are a large group of intracellular parasites widely distributed within many animal groups (Canning and Lom, 1986). Some species, as opportunistic parasites, have developed a significant presence in AIDS patients (Ornstein et al., 1990; Canning and Hollister, 1991; Cali

The Biological Bulletin ; Microsporeans are intracellular parasites; they are located directly in host cell cytoplasm with only a plasma membrane as an interface (1). Microsporeans have an infective spore stage that discharges the sporoplasm from a long, fine tube. The spore has but one plasma membrane which is left behind

The Biological Bulletin ; Microsporidian protozoa are intracellular parasites common in arthropods and fish. The novel feature of these parasites is the extrusion apparatus of the spore stage. The central component of the apparatus is the polar filament, which consists of a membrane-bound paracrystal coil of protein (1).
