Platysporina
Myxobolidae is a family of myxosporean parasites which typically infect freshwater fishes, and includes the economically significant species, '' Myxobolus cerebralis''. They have been shown to have a complex life cycle, involving an alternate stage in an invertebrate, typically an annelid or polychaete worm. Morphology Myxosporean spores of genera belonging to the Myxobolidae are flattened parallel to the sutural line. They typically contain two polar capsules, and have a central vacuole in which they store β-glycogen. In some genera, the spore walls are drawn out into long processes which are thought to slow sinking through the water column. Actinosporean stages which have been linked to members of the Myxobolidae have a single central "style" and three processes or "tails", around 200 micrometers long, projecting from this. A sporoplasm packet at the end of the style contains 64 germ cells surrounded by a cellular envelope. There are also three polar capsules, each of whi ...

Bivalvulida
Bivalvulida is an order of myxosporean parasites which contains a number of species which cause economically significant losses to aquaculture and fisheries, such as ''Myxobolus cerebralis'' and ''Ceratomyxa shasta''. The Myxosporean stages of members of the bivalvulida are characterised by their two spore valves (hence the name), which meet in a "suture line" which encircles the spore. They usually contain two polar capsules, but species have been reported which contain either one or four. Taxonomy and systematics The order Bivalvulida is composed of three suborders and thirteen families. *Suborder Platysporina Kudo, 1919Kudo, R. (1919). Studies on Myxosporidia.

Sporoplasm
Sporoplasm is an infectious material present in the cytoplasm of various fungi-like organisms, such as members of class ''Microsporidia''. Sporoplasm is defined as a mass of protoplasm that gives rise to or forms a spore. The protoplasmic body that is released as an infective amoebula from a cnidosporidian cyst. __TOC__ Mode of infection It is injected to host cell through a coiled polar tube which acts as a spring-like tubular extrusion mechanism. It is mainly involved in the asexual cycle of the organism. Reproduction Inside the host cell, the sporoplasm multiplies to generate meronts, cells with loosely organized organelles enclosed in a simple plasma membrane.{{Cite web, url=https://web.stanford.edu/class/humbio103/ParaSites2006/Microsporidiosis/microsporidia1.html, title=MICROSPORIDIA, website=web.stanford.edu, access-date=2019-12-31 Multiplication occurs either by merogony (binary fission) or schizogony Fission, in biology, is the division of a single entity into ...

Polar Filament
A polar filament is a structure found in the polar capsule of myxosporean organisms. It is analogous to the "penetrant" structure found in cnidocyte A cnidocyte (also known as a cnidoblast or nematocyte) is an explosive cell containing one large secretory organelle called a cnidocyst (also known as a cnida () or nematocyst) that can deliver a sting to other organisms. The presence of this c ...s. The polar filament is coiled along the inner wall of the polar capsule, and is capable of rapid extrusion, during which it everts "inside-out". When everted, it is sticky, and likely serves to hold the spore onto the intestinal wall of the prospective host, and to help separate the valves of the spore. The polar filament is important in species classification. In some species of Ceratomyxa, the polar filament forms a straight basal section, which the rest of the filament coils around, while in the genus Sphaeromyxa, the filament is folded in a zig-zag arrangement rather than being c ...
