Static magnetic field (SMF) is generated in vicinity of moving charge or current passing through conductor. In this study, we aimed to investigate the effect of SMF on the growth of the cultured Entamoeba histolytica (E. histolytica) trophozoites. Different SMF strengths with maximum value equals 30 mT (mT) was applied on the E.histolytica for different periods of times: 0 h, 24 h, 48 h, and 72 h. A modified diphasic liver infusion agar medium was used for culturing E. histolytica in vitro. The results showed the successful stabilization of culture of E. histolytica trophozoites. If we kept the sample for longer time, e. g. 14 days, the growth rate decreases to zero. When applying 10 mT and 15 mT SMF on the sample, it is found that the cultivated E. histolytica trophozoites dies after 4 and 2 days respectively. The experiments suggested that the SMF inhibited the growth and the propagation of E. histolytica cells. In addition, it completely killed all the cells in a short time interval which depend on the SMF strength. It is concluded that the SMFs inhibits the growth of E. histolytica and change the morphology of these cells. Thus, we recommend to use SMF as treatment to mitigate the growth of E. histolytica.

The retromer is a highly conserved eukaryotic complex formed by the cargo selective complex (CSC) and the sorting nexin (SNX) dimer subcomplexes. Its function is protein recycling and recovery from the endosomes to conduct the target molecules to the trans-Golgi network or the plasma membrane. The protozoan responsible for human amoebiasis, , exhibits an active membrane movement and voracious phagocytosis, events in which the retromer may be fully involved.

Protein arginine methyltransferase 5 (PRMT5) is an enzyme that produces monomethyl arginine (MMA) and symmetric dimethyl arginine (sDMA), post-translational modifications that regulate several cellular processes, including stage conversion in parasitic protozoans. , the etiologic agent of human amebiasis, has two stages in its life cycle, the trophozoite, which is the replicative form, and the cyst, corresponding to the infective phase. The study of the molecular mechanisms that regulate differentiation in this parasite has been overdue because of a lack of efficient protocols for in vitro encystment.

Article Synopsis
- The study focused on the prevalence of intestinal protozoan infections among children in Duhok Province, Iraq, from October 2022 to May 2023, involving 740 pediatric patients.
- A total of 205 children (27.7%) tested positive for infections, with the highest rates found in the 5-9 age group, and significant variations in prevalence noted among different age categories.
- The findings indicate that amoebiasis and cryptosporidiosis are more common than previously reported in Iraq, while giardiasis occurred at lower rates, highlighting the need for improved public health measures.

Intestinal protozoan parasitic infections are considered one of the most frequent types of infection caused by these parasites and remain a major health problem for communities. This study aims to detect the frequency of intestinal protozoan infections infection among Zakho general population from October 2018 to June 2022. This cross-sectional study was performed on 2,118 patients referring to private medical diagnostic laboratories in Zakho, Kurdistan Region, Iraq.

During intestinal and liver invasion by the protozoan parasite , extensive tissue destruction linked to large neutrophil infiltrates is observed. It has been proposed that microbicidal components of neutrophils are responsible for the damage, however, the mechanism by which they are released and act in the extracellular space remains unknown. In previous studies, we have shown that trophozoites induce NET formation, leading to the release of neutrophil granule content into extruded DNA.
