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

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.
Viability, infectivity and fatty acid synthetic activity of Perkinsus marinus meront cells incubated in estuarine and artificial seawater.
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.
In artificial seawater, Quinine HCl had a significant effect on LM-TX meront viability (P < 0.
Histologic analysis revealed the presence of a meront stage of an unidentified coccidian parasite in the epithelium of the middle intestine of 3 of the 14 clams examined.
include binary fission; diplokaryotic nuclei; lack of a parasitophorous vacuole, with the thickened plasmalemma of meronts and sporonts in direct contact with host cytoplasm; and vesiculotubular appendages projecting from the plasmalemma (Figure 2, panel A) (5,23).
Renal meronts and gametocytes were confined to the distal convoluted tubules and collecting ducts, and were associated with renal tubular necrosis and tubular obstruction.
In addition, Acroeimeria was reported to have endogenous stages, meronts, and gamonts developing at the microvillus zone of the host cell and enclosed within the microvillus boundary, extending above the intestinal mucosal surface.
The intestinal MLO parasites in geoducks had a plasmodium-like morphology, which may represent meronts, whereas the siphon muscle MLO contained spore-like stages.
