We report a case of amoebic appendicitis without colitis symptoms. Acute appendicitis is commonly encountered by gastroenterologists in their daily practice. The number of cases of amoebiasis increases annually in Japan, and is thought to be associated with an increase in sexually transmitted disease or travel to endemic areas. However, acute amoebic appendicitis is rare and the prognosis is ve...

The demonstration of antibodies in syphilitic sera that will immobilize Treponema pallidum (Nelson and Mayer, 1949) led Cole and Kent (1953) to investigate and demonstrate that immune rabbit sera were capable of immobilizing Entamoeba histolytica, and to suggest that sera from human cases of amoebiasis might show the same phenomenon. Their rabbit sera did not show immobilizing activity to a hig...

Patients ranged from those with no prior diagnosis of or suspected exposure to Entamoeba histolytica to those with proven amoebic liver abscesses (extraintestinal disease). A comparison of serologies from patients with proven and suspected amoebiasis or possible past exposure revealed good correlation between the indirect fluorescent antibody (IFA) procedure and the other methods used, counteri...

A comparison is made of enzyme-immunoassay and radio-immunoassay for the detection of antibody in Chagas's disease, sleeping sickness, malaria, schistosomiasis ans invasive amoebiasis. Both assays were sensitive and reproductible and gave comparable results.

It is now well established that Entamoeba moshkovskii and Entamoeba dispar are two distinct nonpathogenic species, but microscopically indistinguishable from the pathogenic species E. histolytica, the causative organism of amoebiasis. Traditionally diagnosis of E. histolytica infection has relied upon microscopic examination of cyst or trophozoite stage in fresh or fixed stool specimens which h...

Amoebiasis continues to be a major cause of morbidity and mortality in children in developing countries. Entamoeba histolytica infections are commonly observed in tropical and subtropical regions of the world including Iran. In developed countries Entamoeba histolytica infections are commonly seen in travelers, recent immigrants, homosexual men, and inmates of institutions. The disease is more ...

Metronidazole has many unique properties such as possessing antibacterial well anti-protozoal activity, very minimal resistance rate, acceptable safety profile and market longevity. remained the recommended drug in treatment of any form amoebiasis caused by Entamoeba histolytica since its inception almost half a c entury ago. Anaphylaxis which limits use agents is hardly reported with metronida...
