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.

阿米巴原虫（学名：Amoeba）单细胞真核生物，主要指肉足鞭毛门、肉足亚门、根足超纲的叶足纲生物 [1-2]。 别称变形虫，源自希腊语“amoibe”，意思是“变化”。 阿米巴原虫通过伸长或收缩伪足不断改变自身形状，借此进行运动及进食，这种运动方式称为阿米巴样运动。 因此，阿米巴原虫没有固定形状，其伪足的形态和内部结构作为分类的依据之一。 [3-4] 阿米巴原虫的大小差异较大，最小的仅2~3微米，较大可达肉眼可见的5毫米。 [4] 根据生活环境的不同，可分为内阿米巴 …

溶组织内阿米巴（學名： Entamoeba histolytica ）又稱痢疾阿米巴、赤痢變形蟲，是一种厌氧的原生动物，属于内阿米巴属 [1] 。溶组织内阿米巴主要感染人类和其他灵长类动物，估计感染全球总人数约为50万人。

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.

溶组织内阿米巴(Entamoeba histolytica Schaudinn, 1903)属内阿米巴科的内阿米巴属。 过去认为，溶组织内阿米巴一般在宿主结肠内共栖，只是在一定条件下侵入肠壁或由血流带到其他器官并引起疾病。

2023年4月17日 · Entamoeba histolytica is a protozoan that causes intestinal amebiasis as well as extraintestinal manifestations. Although 90 percent of E. histolytica infections are asymptomatic, nearly 50 million people become symptomatic, with about 100,000 deaths yearly. Amebic infections are more prevalent in countries with lower socioeconomic conditions.

2024年5月2日 · Amebiasis is a disease caused by the parasite Entamoeba histolytica. Amebiasis is more common in people living in tropical areas with poor sanitary conditions or people traveling to these areas. Antibiotics are effective in treating amebiasis.

The genus Entamoeba covers several amoebae that reside mainly in the human gastrointestinal tract, of which Entamoeba histolytica is responsible for causing intestinal amebiasis (IA) and amoebic liver abscess (ALA) in humans, leading to annual deaths of 100,000 worldwide.

Several species of amebae are capable of colonizing the human gastrointestinal tract but, in contrast to Entamoeba histolytica, are not considered pathogenic. The nonpathogenic intestinal amebae include several Entamoeba species (E. coli, E. hartmanni, and E. polecki), Endolimax nana, and Iodamoeba buetschlii (=I. bütschlii).

2023年7月10日 · Entamoeba histolytica is an anaerobic, protozoan parasite that infects humans and other primates. 1 Infection can occur when a person ingests water or food that has been contaminated with fecal material containing mature E histolytica cysts — the infective stage of the parasite — or ingests E histolytica cysts present on their fingers or on ...
