Plasmodium pifanoi is a parasite of the genus Plasmodium subgenus Paraplasmodium. As in all Plasmodium species, P. pifanoi has both vertebrate and insect hosts. The vertebrate hosts for this parasite are lizards.

Taxonomy

[edit]

This species was first described by Scorza and Dagert in 1956. It was redescribed in 2003 by Telford.[1]

Description

[edit]

The asexual stages are irregular in shape and do not have a vacuole.

Schizonts measure 6.2 × 4.5 micrometres (range: 4 – 8 × 3 – 6) and produce on average 11.9 (range: 7 – 16) merozoites.

Gametocytes average 12.4 × 6.0 micrometres (range: 8 – 16 × 4 – 10). The average length × width product is 72.9 (range: 52 – 112) and the average length / width ratio is 2.18 (range: 1.1 – 3.3). The gametocytes always contain 1 – 5 prominent vacuoles.

Macrogametocytes during active infection are longer than microgametocytes with a greater length-width product. Gametocytes in chronic infection are slightly smaller and are not sexually dimorphic in their dimensions.

Distribution

[edit]

Found in Venezuela, South America.

Hosts

[edit]

Known hosts are the lizards Ameiva ameiva and Kentropyx calcarata.
