A stage in the life cycle of sporozoans in which multiple asexual fission (schizogony) occurs, resulting in production of merozoites.

It has been suggested that malarial parasites contain a toxin that is released at meront rupture, which results in the genesis of fever and other manifestations (46) and results in release and activation of cytokines, such as tumour necrosis factor-alpha (TNF-[alpha]) and interleukin-1 (IL-1) from macrophages and monocytes.
Multiple fission (schizogony) occurs; resulting in the formation of eight merozoites within the meront (referred to as type I meronts).
During 24-h incubations in vitro, meront stages remained within the colony matrix of intermediate filaments and showed evidence of motor activity, including some endocytosis.
1, mature oocyst surrounded by outer layer (OL) and inner layer (IL) membrane and containing four sporocysts (SPC); 2, mature oocysts containing sporocysts (SPC) and free sporozoites (SP); 3, uninucleated (UN) and premature meront (PM); 4, infection of epithelial cell by two parasites, meront (M) and macrogamont (Ma), the host cell is displaced into the lumen but still attached to the underlying epithelium via a stalk- like structure.

The acyl elongation reaction in the meront (trophozoite) stage of this parasite is catalyzed by a FAE like ketoacyl-CoA synthase class of condensing enzyme previously only reported in higher plants and algae (Venegas-Caleron et al.
