Apr 17, 2023 · Those infected by Entamoeba are mostly colonized by either E. histolytica or E. dispar. E. histolytica is the pathogenic form and can cause amoebic colitis and extraintestinal amoebiasis. E. dispar is considered to be nonpathogenic and causes no signs of disease.
Dec 2, 2018 · Finally, the assumption that E. histolytica is the only pathogenic species capable of causing disease should be reconsidered. New evidence demonstrates that E. dispar is a potential pathogen capable of causing disease [17–19]. Therefore, new treatment guidelines may be warranted.

Feb 16, 2022 · Most Entamoeba infections in humans appear to be caused by non-pathogenic species (e.g. Entamoeba dispar and Entamoeba coli ), the only amoebic species that could become virulent and harm the host is Entamoeba histolytica, the causative agent of amoebiasis, responsible for dysentery and liver abscesses [ 7 ].

E. histolytica, as its name suggests ( histo – lytic = tissue destroying), is pathogenic; infection can be asymptomatic, or it can lead to amoebic dysentery or amoebic liver abscess. [6] [7] Symptoms can include fulminating dysentery, bloody diarrhea, weight loss, fatigue, abdominal pain, and amoeboma.

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.
Several species are found in humans and animals. Entamoeba histolytica is the pathogen responsible for invasive ' amoebiasis ' (which includes amoebic dysentery and amoebic liver abscesses ). Others such as Entamoeba coli (not to be confused with Escherichia coli) and Entamoeba dispar [3] are harmless.
Nov 1, 2019 · Entamoeba histolytica is classified as a category B priority biodefense pathogen by the National Institute of Allergy and Infectious Diseases (NIAID) ( Shirley et al., 2018 ). To date, there is no vaccine to prevent amebiasis.
