Feb 13, 2017 · Entamoeba histolytica occurs in the following forms, the trophozoites, precyst, cyst, metacyst, and metacystic trophozoite. The trophozoite is about 10–60 μm in size with a clear finely granular cytoplasm and a spherical nucleus that shows aggregation of chromatin beads at the nuclear membrane and a centrally located karyosome.

Fact 1: Rodent models do not mimic the entire life cycle of E. histolytica. Entamoeba histolytica is an extracellular enteric eukaryotic parasite. Globally, an average of 50 million cases and 55,000 to 100,000 deaths are due to E. histolytica infection each year, primar-ily impacting the developing world [1,2].

Entamoeba histolytica is a protozoan parasite of humans, and causative agent of amoebiasis. The parasite exists in two forms; an infective, non-dividing cyst stage and an actively dividing, invasive trophozoite. The dormant, non-motile cyst, upon ingestion by the host, gets converted to the actively dividing trophozoite in the colon.

Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba. [1] Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide. [1] E. histolytica infection is estimated to kill more than 55,000 people each year. [2]

Jan 1, 2014 · The life cycle of E. histolytica has been described by Dobell (1928) and comprises an infective cyst form, metacystic trophozoite, invasive motile feeding trophozoite, precyst and metacyst stages. Infection occurs following ingestion of mature cysts (10–16 μm) which contain up to four nuclei, in faecally contaminated food, water, on hands or ...
The stage conversion process remains poorly understood despite being central to amoebic biology. In this review, we will highlight recent progress in our understanding of Entamoeba stage conversion including dissecting transcriptome analysis in development, characterization of transcriptional networks, demonstration of epigenetic regulation ...
