schizogony

[ski′zäg·ə·nē]
(invertebrate zoology)
Asexual reproduction by multiple fission of a trophozoite; a characteristic of certain Sporozoa.

Schizogony

 

multiple asexual reproduction in protozoans, including foraminiferans, trypanosomes, and sporozoans, as well as in some algae. In schizogony, the nucleus of the maternal individual undergoes a succession of rapid divisions into several nuclei and breaks down into the corresponding number of mononuclear cells (merozoites). The sexual process begins after several asexual generations. Sporozoan merozoites penetrate the host cells and give rise to gametocytes, from which gametes are formed.

This would negatively affect the erythrocytic schizogony. Decreased clearance rate by macrophages would only guarantee successful multiplication of the merozoites through the erythrocytic schizogonic cycle.
Two types of schizonts are produced by schizogony; the first small schizonts are produced in the Kupffer cells.
Schizogony inhibition (%) = schizonts in control schizonts with extract x 100/ schizonts in control.
Microscopic examination of the cytospin preparations revealed the highest rates of parasite schizogony between 15[degrees]C and 25[degrees]C, and no schizogony between 30[degrees]C and 35[degrees]C, in both isolates.
In these cells, the parasites undergo asexual multiplication (schizogony or merogony) and then sexual multiplication (gametogony) producing microgamonts (male) and macrogamonts (female).

Most parasitized red cells are then destroyed, either by rupture at schizogony or by premature phagocytosis by monocytes and macrophages.
