[edit] Description
The parasite was first described by Lainson et al in 2001. [1]
Young asexual stages are initially polar in the erythrocyte but with matuation, move to a lateral position. The larger meronts may slightly enlarge the erythrocyte but most asexual stages do not. Conspicuous greenish-black pigment granules are located in a distinct vacuole.
The largest schizonts contain 30-40 nuclei.
The gametocytes are at first polar in the erythrocyte but gradually move to a lateral position. They eventually assume a smooth, curved cylindrical shape with evenly rounded ends. Pigment is scattered or concentrated around a conspicuous vacuole which is slowly developed as the gametocytes mature. The mature gametocytes occasionally enlarge the erythrocyte.
Mature male parasites measured 11.8 x 4.0 micrometres (range: 9.6 x 4.2 - 13.2 x 3.6 micrometres) and females 13.5 x 4.5 micrometres (range: 12.0 x 4.5 - 15.0 x 4.8 micrometres).
[edit] Geographical occurrence
This species is found in Brazil and Surinam, South America.
[edit] Clinical features and host pathology
The only known host is the teiid lizard Kentropyx calcarata.
