Entamoeba is a genus of Amoebozoa found as internal parasites or commensals of animals. In 1875, Fedor Lösch described the first proven case of amoebic dysentery in St. Petersburg, Russia. He referred to the amoeba he observed microscopically as Amoeba coli; however, it is not clear whether he was using this as a descriptive term or intended ...
Entamoeba hartmanni. (Show more) Entamoeba, protozoan genus of the rhizopodian order Amoebida. Most species are parasitic in the intestines of many vertebrates, including humans; E. histolytica is the cause of human amebic dysentery. The cell nucleus, which is distinctive for the genus, contains a central body, the endosome, and a ring of ...

genus Entamoeba on the basis of nuclear appearance alone. It is the taxonomic ranks below that of genus that cause the majority of problems in the nomenclature and taxonomy of Entamoeba . The simplicity of the cell struc-ture and lack of a Þ xed shape undermine the use of morphological features in spe-
Dec 16, 2010 · Abstract. Entamoeba histolytica is a human pathogen that causes amoebic dysentery and leads to significant morbidity and mortality worldwide. Understanding the genome and evolution of the parasite will help explain how, when and why it causes disease. Here we review current knowledge about the evolutionary genomics of Entamoeba: how differences ...

Nov 1, 2019 · Entamoeba in humans. A total of 110 studies from 47 countries were used to calculate epidemiological figures. The overall molecular prevalence of Entamoeba infection was 3.55% (3817/107396) in humans worldwide. Globally, the prevalence ranged from 1.72% (Oceania) to 21.58% (North America) ( Fig. 1 ).

Nov 18, 2014 · 1 Background. Amebae of the genus Entamoeba are easily recognized by their distinctive nucleus, which is usually described as being a “ring and dot” in appearance. The ring describes “peripheral chromatin” that lines the inside of the nuclear membrane, and the dot is generally referred to as the karyosome.

Nov 18, 2014 · The diversity seen within some Entamoeba species, such as within Entamoeba coli or Entamoeba moshkovskii , may indicate that in fact two or more species have been classified under the same name. Figure 3.1b illustrates the phylogenetic relationships among a small sample of Entamoeba species.
