Myxozoa (etymology: Greek: μύξα myxa "slime" or "mucus" [2] + thematic vowel o + ζῷον zoon "animal" [3]) is a subphylum of aquatic cnidarian animals – all obligate parasites. It contains the smallest animals ever known to have lived.
Myxosporea is a class of microscopic animals, all of whom are parasites.They belong to the Myxozoa clade within Cnidaria.They have a complex life cycle that comprises vegetative forms in two hosts—one an aquatic invertebrate (generally an annelid but sometimes a bryozoan) and the other an ectothermic vertebrate, usually a fish.
The life cycle of T. kitauei involves two hosts. Branchiura sowerbyi (Oligochaeta, Naididae, Branchiurinae) is the definitive host, in which actinosporean spores of the aurantiactinomyxon type are formed and released from the intestinal tract of the worms. These actinospores then infect the intermediate host, common carp, and after parasite ...
Kudoa is a genus of Myxozoa and the only genus recognized within the monotypic family Kudoidae. There are approximately 100 species of Kudoa all of which parasitize on marine and estuarine fish. [1] Kudoa are most commonly known and studied for the negative effects the genus has on commercial fishing and aquaculture industries. [2]
Tetracapsuloides bryosalmonae, the only representative of the group whose life cycle is well studied, causes proliferative disease of the kidneys in salmonids. Two stages of the life cycles of the two species in the genus Buddenbrockia are known. One of them is a saccular stage, similar to Tetracapsuloides.
Enteromyxum leei was formerly described as Myxidium leei, [4] and initially reported in cultured gilthead sea bream (GSB) (Sparus aurata) from southern Cyprus.The morphology of the myxospores of this parasite differ slightly from others of the family Myxiidae: the polar capsules are located terminally and are elongated rather than subspherical (as in Myxidium), but they open to one side and ...

Myxobolus is a genus of myxozoa that includes important parasites of fish [1] like Myxobolus cerebralis. The genus is polyphyletic , with members scattered throughout the myxozoa. Some stages of Myxobolus species were previously thought to be different organisms entirely, but are now united in this group.
