mi·cro·spor·id·i·a

(mī'krō-spōr-id'ē-ă),
Common name for members of the protozoan phylum Microspora. It includes some 80 genera parasitizing all classes of vertebrates and many invertebrates, especially the insects. Several genera, such as Encephalitozoon, Enterocytozoon, Nosema, Vittaforma, Pleistophora, and Trachipleistophora have been implicated in the infection of immunocompromised humans.

Microsporidia

A phylum of ubiquitous spore-forming unicellular parasites, which have been reclassified as fungi. Microsporidia have a long polar filament and a polar cap that serves as a means of extrusion. They primarily infect infects, but crustaceans, fish and humans are not immune. Of the estimated million species of Microsporidia, 1500 have been formally named.

Microsporidia genera that cause human disease
• Brachiola—B algerae, B connori, B vesicularum.
• Encephalitozoon—E cuniculi, E hellem, E intestinalis.
• Enterocytozoon—E bieneusi (prolonged production of intra- and extracellular spores by Enterocytozoon bieneusi is not always associated with systemic disease).
• Microsporidium—M ceylonensis, M africanum.
• Nosema—N ocularum.
• Pleistophora species.
• Trachipleistophora—T hominis, T anthropophthera.
• Vittaforma species—V corneae.

Microsporidia

Parasitology A phylum of ubiquitous unicellular obligate intracellular protozoans–eg, Enterocytozoon, which infect insects and vertebrates, and humans. See Encephalitozoon species.

Microsporidia

an order of the subphylum Sporozoa characterized by having small spores and one polar capsule. Common occurrence is as parasites of arthropods and fish. Includes nosema. In finfish may cause xenomas, in crustaceans cause 'cotton flesh'.
