Amebiasis can be considered the most aggressive disease of the human intestine, responsible in its invasive form for clinical syndromes, ranging from the classic dysentery of acute colitis to extra-intestinal disease, with emphasis on hepatic amebiasis, unsuitably named amebic liver abscess. Found worldwide, with a high incidence in India, tropical regions of Africa, Mexico and other areas of C...

Amebiasis is the third leading parasitic cause of death worldwide, and it is not known whether immunity is acquired from a previous infection. An investigation was done to determine whether protection from intestinal infection correlated with mucosal or systemic antibody responses to the Entamoeba histolytica GalNAc adherence lectin. E. histolytica colonization was present in 0% (0/64) of child...

Amebiasis is an infection caused by the intestinal protozoan Entamoeba histolytica (E. histolytica). About 90% of infections are asymptomatic, and the remaining 10%of infections produce a spectrum of clinical syndromes ranging from dysentery to abscesses of the liver or other organs. Most asymptomatic carriers harbor nonpathogenic strains {E. dispar) which do not cause invasive disease. Some pa...

Amebiasis is common in tropical and developing countries with variable symptoms. Ameboma of the colon occurs rarely due to the annular growth of granulation tissue and can present as mass lesion simulating colonic carcinoma in elderly individuals. Due to diagnostic dilemma or in case of complications, for example, acute intestinal obstruction, perforation, or bleeding per rectum, the patient re...

Amebiasis is a relatively common disease in the tropical region of the world especially in the Indian subcontinent. Extra-intestinal dissemination happens through the portal route and hence the liver is the most common site for the same. Other sites can be also involved albeit less commonly. Pericardial involvement is mostly due to extension of the infection of the left lobe of liver due to ana...

The protozoan parasite Entamoeba histolytica is responsible for invasive intestinal and extraintestinal amebiasis. The virulence of Entamoeba histolytica is strongly correlated with the parasite's capacity to effectively kill and phagocytose host cells. The process by which host cells are killed and phagocytosed follows a sequential model of adherence, cell killing, initiation of phagocytosis, ...

We are concerned in this article with six intestinal parasitoses-the four main soiltransmitted helminthiases (ascariasis, trichuriasis, hookworm infection, and strongyloidiasis) and the two leading intestinal protozoan infections (amebiasis and giardiasis). These two groups of parasitoses depend on fecal contamination, but there is a significant epidemiologic difference between them. That is, t...

Background: Entamoeba (E.) histolytica, is a protozoan parasite that causes intestinal and extraintestinal amebiasis, leading to significant morbidity mortality in developing nations. E. dispar, moshkovskii, members of E.histolytica complex species, are all morphologically similar. Aim the study: The current work aimed utilize molecular techniques for identifying exact prevalence histolytica sp...

Entamoeba histolytica (Eh) is an extracellular protozoan parasite of humans that invades the colon to cause life-threatening intestinal and extra-intestinal amebiasis. Colonized Eh is asymptomatic, however, when trophozoites adhere to host cells there is a considerable inflammatory response that is critical in the pathogenesis of amebiasis. The host and/or parasite factors that trigger the infl...
