Amoebic liver abscess production by Entamoeba dispar

Amoebic liver abscess production by Entamoeba dispar.

Although Entamoeba dispar displays a similar morphology to Entamoeba histolytica, cellular and molecular studies have revealed significant differences between these two amoebae, including the former being characterized as non-pathogenic and the later as pathogenic. However, recent in vivo and in vitro experiments have shown that E. dispar strains of different origin are capable of...

A Brazilian species of Entamoeba dispar (ADO) produces amoebic liver abscess in hamsters.

Amoebic liver abscess.

Sonography is a major advance in the diagnosis of ALA. Identification of amoebic antigen in the pus is a specific immunodiagnostic test. Medical therapy with a single drug (metronidazole) is adequate in most instances. Routine needle aspiration or surgical drainage are not indicated. The abscess cavity may take up to 18 months for resolution and demonstration of such a lesion does not warrant r...

Amoebic Liver Abscess: Revisited

Amoebiasis is common in Asia, Africa, and South America, and is endemic in many regions of the Philippines1-4. Hepatic involvement is a frequent extra-intestinal complication which is encountered in 3 to 9% of the cases of amoebiasis. In Africa, over a period of 20 years, the King Edward VIII Hospital reported 2,074 cases of hepatic abscess, while in New York City at the Mt. Sinai Hospital only...

Fate of Entamoeba histolytica during establishment of amoebic liver abscess analyzed by quantitative radioimaging and histology.

The protozoan parasite Entamoeba histolytica is the causative agent of amoebiasis, a human disease characterized by dysentery and liver abscess. The physiopathology of hepatic lesions can be satisfactorily reproduced in the hamster animal model by the administration of trophozoites through the portal vein route. Hamsters were infected with radioactively labeled amoebas for analysis of liver abs...
