Amebiasis in schistosomiasis endemic and non-endemic areas in Egypt

ABSTRACT

Stool and blood specimens were collected from each of 404 and 576 individuals at Sindbis Village [Qalyoubia Governorate] in the Nile Delta, where schistosomiasis is endemic, and El-Rashda Village [New Valley Governorate] in the Western Desert of Egypt where there is no schistosomiasis, respectively. The prevalence of infection with entamoeba [E. histolytica and/or E. dispar] was higher at Sindbis than at El-Rashda Village. Serum antibodies developed only against E. histolytica. Only 16 - 17% of those who were positive microscopically can be considered infected with E. histolytica as determined serologically. At Sindbis, the prevalence of E. histolytica infection was lower in S. mansoni negative than in S. mansoni positive individuals
