   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.

   Where does Entamoeba histolytica live?

   • Habitat: Trophozoites of E. histolytica live in the mucosal and submucosal layers of the large intestine of man . Life cycle of Entamoeba histolytica has two-stage: motile trophozoite and non-motile cyst. Trophozoites are found in intestinal lesions, extra-intestinal lesions, and diarrheal stools whereas cyst predominates in non-diarrheal stools.

   How does Entamoeba histolytica spread?

   • Infection with Entamoeba histolytica (and E.dispar) occurs via ingestion of mature cysts from fecally contaminated food, water, or hands. Exposure to infectious cysts and trophozoites in fecal matter during sexual contact may also occur. Excystation occurs in the small intestine and trophozoites are released, which migrate to the large intestine.

   When was Entamoeba histolytica discovered?

   • Councilman and Luffleur identified amoebae from hepatic abscesses in 1889. They mentioned the presence of red blood cells (RBCs) inside the trophozoites and called them E. dysenteriae. However, Fritz Schaudinn gave the Latin name Entamoeba histolytica, in the year 1903 . He suggested its pathogenic effect on tissue. This name “E. histolytica was

   Pathogenic Entamoeba species must be differentiated from other intestinal protozoa such as the nonpathogenic amebae (Entamoeba coli, E. hartmanni, E. gingivalis, Endolimax nana, Iodamoeba buetschlii) and the flagellate Dientamoeba fragilis. Morphologic differentiation among these is possible, but potentially complicated, based on morphologic ...

   Nov 22, 2023 · Intestinal amebiasis is caused by the protozoan Entamoeba histolytica. There are four species of intestinal amebae with identical morphologic characteristics: E. histolytica, E. dispar, E. moshkovskii, and E. bangladeshi [ 1,2 ]. Most symptomatic disease is caused by E. histolytica; E. dispar is generally considered nonpathogenic.
