Garniidae
Encyclopedia
Garniidae is a family
of parasitic protozoa
in the phylum
Apicomplexia.
Like many species in the Apicomplexia all species
in this family have two host
s in their life cycle – one in a vertebrate
and one invertebrate
. The vertebrate hosts are reptile
s or bird
s but the invertebrate hosts are not known for many of the species.
Species in this family are parasites of erythrocytes and diverse white blood cells. They do not produce pigment but do have an asexual cycle in the blood
.
The type genus is Garnia

Taxonomy
There are currently three genera recognised in this family- FallisiaFallisiaFallisia is a genus of the family PlasmodiidaeThe genus was created by Lainson, Landau and Shaw in 1974. A revision of the genus Plasmodium by Levine in 1985 considered this subgenus to be a synonom of Plasmodium. The description of a new species Plasmodium siamense by Telford in 1986 lead to a...
