Special remarks:
INTRODUCTION
Entamoeba histolytica is an anaerobe parasite forming cysts which have four small nuclei and measure 10-15 µm in diameter. The cysts  are  sturdy  and resist  adverse  environmental  conditions.  After  ingestion  by  a  susceptible  host  (invertebrates  and  vertebrates including humans), its wall is disrupted by the formation of a small opening through which an amoeba emerges. The amoeba divides serially through three cycles giving rise to eight uninucleate trophozoites from one cyst which are motile and measure 20-30 µm in diameter. Some of the trophozoites then invade the tissues of the large intestine and may erode them so extensively that they gain entrance into the bloodstream. Thus, amoebae can reach all parts of the body. Infection with Entamoeba histolytica has worldwide distribution. It is the causative agent of amoebiasis and amoebic dysentery and inhabits the lumen and mucosa of the large intestine, predominantly the transverse colon and cecum. Extra intestinal amoebiasis can afflict any organ or tissue. The majority of infected individuals  are  free  of  symptoms;  this  high  incidence  of  asymptomatic  carriers  complicates matters.  Those  who  are  symptomatic experience a wide range of manifestations. Members of all age groups and both sexes are infected. The risk of infection increases with inadequate  sanitary  conditions.  An  increased prevalence  of  amoebiasis  is  found  among  people,  who  have  an  increased  risk of exposure in the agricultural occupations and in male homosexuals.
