Learn about Entamoeba histolytica, a pathogenic ameba that causes intestinal and extraintestinal infections. Find out how to identify trophozoites and cysts, and how to diagnose amebiasis in the laboratory.
Apr 17, 2023 · There are two forms E. histolytica can take: the cyst form, which can survive in the environment for a prolonged period, and the trophozoite stage, which is the active and invasive form. After the ingestion of the cyst form, trophozoites can be formed, which can invade and penetrate intestinal mucosa destroying epithelial cells and inflammatory ...

E. histolytica induces tissue damage by three main events: direct host cell death, inflammation, and parasite invasion. Once the trophozoites are excysted in the terminal ileum region, they colonize the large bowel, remaining on the surface of the mucus layer and feeding on bacteria and food particles.
Dec 2, 2018 · Entamoeba histolytica is the responsible parasite of amoebiasis and remains one of the top three parasitic causes of mortality worldwide. With increased travel and emigration to developed countries, infection is becoming more common in nonendemic areas.

Nov 22, 2023 · Learn about the causes, transmission, and diagnosis of intestinal amebiasis, a parasitic infection caused by E. histolytica. The trophozoite stage of the parasite is the form that causes invasive disease and can be seen on microscopy.
Oct 6, 2022 · Learn about the trophozoite stage of E. histolytica, a parasite that causes amoebic dysentery and liver abscess. Find out how trophozoites are transmitted, invade, and produce lesions in the intestine and other organs.
Aug 19, 2019 · This review article summarizes the recent advances in understanding the biology and pathology of E. histolytica trophozoites through transcriptome-level studies. It covers topics such as gene expression patterns, regulation, virulence factors, stress responses, and encystation.
