Eimeria bovis-induced modulation of the host cell proteome at the meront

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.
Viability, infectivity and fatty acid synthetic activity of Perkinsus marinus meront
cells incubated in estuarine and artificial seawater.
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.
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.
Sporozoites originated meronts
which, upon maturation, release merozoites that penetrate endothelial cells to originate secondary merozoites.
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).
