Myxobolidae
Myxobolidae is a Family (biology), 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 suture (anatomical), sutural line. They typically contain two polar capsules, and have a central vacuole in which they store glycogen, 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. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Myxosporea
Myxosporea is a class of microscopic parasites, belonging to the Myxozoa clade within Cnidaria. They have a complex life cycle which comprises vegetative forms in two hosts, an aquatic invertebrate (generally an annelid but sometimes a bryozoan) and an ectothermic vertebrate, usually a fish. Each host releases a different type of spore. The two forms of spore are so different that until relatively recently they were treated as belonging to different classes within the Myxozoa. Taxonomic status The taxonomy of both actinosporeans and myxosporeans was originally based on spore morphology. In 1994 the phylum Myxozoa was redefined to solve the taxonomic and nomenclatural problems arising from the two-host life cycle of myxozoans. The distinction between the two previously recognised classes Actinosporea and Myxosporea disappeared and the class ''Actinosporea'' was suppressed, becoming a synonym of the class ''Myxosporea'' (Bütschli, 1881). The generic names of actinosporeans were r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myxobolus Cerebralis
''Myxobolus cerebralis'' is a myxosporean parasite of salmonids (salmon and trout species) that causes whirling disease in farmed salmon and trout and also in wild fish populations. It was first described in rainbow trout in Germany in 1893, but its range has spread and it has appeared in most of Europe (including Russia), the United States, South Africa, Canada and other countries due to the aid of humans of shipments of cultured and wild fish. In the 1980s, ''M. cerebralis'' was found to require a tubificid oligochaete (a kind of segmented worm) to complete its life cycle. The parasite infects its hosts with its cells after piercing them with polar filaments ejected from nematocyst-like capsules. This infects the cartilage and possibly the nervous tissue of salmonids, causing a potentially lethal infection. Causing the host to develop a black tail, spinal deformities, and possible more deformities in the anterior part of the fish. Whirling disease affects juvenile fish (fin ...
