The Plasmodiidae are a family of apicomplexan parasites, including the type genus Plasmodium, which is responsible for malaria. This genus was created in 1903 by Mesnil. They are one of the four families in the order Haemospororida. The latest addition to the family was made in 2011, with the extinct genus Vetufebrus (also with the extinct species Vetufebrus ovatus).[1]
[edit] Diagnostic criteria
The diagnostic criteria of the Plasmodiidae are:
- macrogametes and microgamonts develop independently
- syzygy absent
- microgametocyte produces 8 flagellated microgametes
- zygote is motile (known as an ookinete)
- conoid present in ookinete stage only
- sporozoites naked in oocyst (that is without a sporocyst)
- sporozoites have three walls.
- heteroxenous: merogony and gamogony occur in vertebrate host and fertilization and sporogony in definitive host (a blood sucking insect)
- hemozoin pigment is produced
