Diagnostic criteria

The diagnostic criteria of the Plasmodiidae are:
  • macrogametes and microgamonts develop independently
  • syzygy absent
  • microgametocyte produces 8 flagellated microgametes
  • zygote
    Zygote
    A zygote , or zygocyte, is the initial cell formed when two gamete cells are joined by means of sexual reproduction. In multicellular organisms, it is the earliest developmental stage of the embryo...

  • hemozoin pigment is produced

Taxonomy

The order has four families: the Garniidae, the Haemoproteidae, the Leucocytozoidae and the Plasmodiidae.

The Haemoproteidae and the Plasmodiidae both produce pigment. These families have been placed in the order Laveraniina.

Neither the Haemoproteidae or the Leucocytozoidae have an asexual cycle in the peripheral blood.

The Garniidae do not produce pigment but do have an asexual cycle in the blood.

The genus Mesnilium is the only group that infects fish. The genus has a single species and has been reported only once. It may be that this genus has been mistakenly placed in this genus. DNA studies are likely to be needed to clarify this point.
