Oct 31, 2022 · Generally, the docking of membrane proteins for vaccination involves five key stages: (1) the selection and antigenic evaluation of proteins, (2) the prediction of B-cell epitopes and T-cell epitopes, (3) the non-allergenicity and non-toxicity prediction of selected T-cell epitopes, (4) structural modeling and molecular docking, and finally, (5 ...

Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease. Entamoeba histolytica is well recognized as a pathogenic ameba, associated with intestinal and extraintestinal infections. The other species are important because they may be confused with E. histolyticain diagnostic investigations.
Cysts and trophozoites are passed in feces . Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. Infection by Entamoeba histolytica occurs by ingestion of mature cysts in fecally contaminated food, water, or hands. Excystation occurs in the small intestine and trophozoites are released, which migr...

Mature Entamoeba histolytica/Entamoeba dispar cysts have 4 nuclei that characteristically have centrally located karyosomes and fine, uniformly distributed peripheral chromatin. Cysts usually measure 12 to 15 µm.
May 21, 2021 · Membrane proteins can be found on the cell surface, reticulum endoplasm (ER), Golgi apparatus, endomembrane, mitochondria and nucleus. In E. histolytica , host–parasite interactions occur on the membrane surface, which is the outer layer of the trophozoites, and the adherence process is initiated by Gal/GalNAc lectin membrane protein, which ...

Entamoeba cells are small, with a single nucleus and typically a single lobose pseudopod taking the form of a clear anterior bulge. They have a simple life cycle. The trophozoite (feeding-dividing form) is approximately 10-20 μm in diameter and feeds primarily on bacteria. It divides by simple binary fission to form two smaller daughter cells.

Oct 5, 2016 · Abstract. The ultrastructure of the trophozoite of Entamoeba histolytica cultivated in vitro on artificial media is described from electron-microscope studies made by the authors and from other published accounts. The authors point out that the description does not present a complete picture of the trophozoite of this species of amoeba since no ...
Dec 5, 2006 · Entamoeba histolytica cells, the cause of amoebic dysentery, are highly motile, and this motility is an essential feature of the pathogenesis and morbidity of amoebiasis. However, the control of E. histolytica motility within the gut and during invasion is poorly understood. We have used an improved …
