Entamoeba histolytica was first cultured in vitro in 1925 (Boeck and Drbohlav, 1925) but has not yet been grown in the absence of living bacteria. Experimentally the dependence of E. histolytica on living bacteria in the intestine is well illustrated by the inability of E. histolytica to survive and invade the bowel wall of germ-free guinea-pigs (Phillips, Wolfe, Rees, Gordon, Wright, and Reyni...

Introduction Amoebiasis, which is caused by the intestinal protozoan Entamoeba histolytica, is a ubiquitous parasitic infection affecting approximately 10% of the world's population and causing more deaths every year (100,000 deaths) than any other parasitic infection, with the exception of malaria and schistosomiasis [1–3]. Most individuals with an E. histolytica infection are asymptomatic, bu...

Radiological abnormalities were observed in 88-3% of patients with the syndrome of hepatic amoebiasis. While this figure is higher than those reported in previous studies, it appears that it is due to the large number of patients who showed an elevation of the diaphragm in the right lateral views ofthe chest. It was observed that a proportion of the patients with an elevation of the right dome ...

Entamoeba histolytica is the pathogenic species of Entamoeba that causes amoebic dysentery and other invasive disease. The morphologically similar species, E. dispar, is non-pathogenic and accounts for about 90% of the previously estimated 500 million E. histolytica infections world-wide. Because of the recent redefinition of E. histolytica and E. dispar, and the limited number of drugs availab...
