The Plasmodiidae are a family of apicomplexan parasites, including the type genus Plasmodium, which is responsible for malaria. This family was erected in 1903 by Mesnil and is one of the four families in the order Haemospororida.

Taxonomy

[edit]

The family Plasmodiidae has three sister taxa in the order Haemospororida: the families Garniidae, Haemoproteidae, and Leucocytozoidae.

The Haemoproteidae and the Plasmodiidae both produce pigment, and these have been placed in the suborder Laveraniina.

Neither the Haemoproteidae nor 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. They appear to be the earliest diverging clade in this group.

The Plasmodiidae contain these genera:

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