Abstract
OBJECTIVE
Humans may be infected with three morphologically identical Entamoeba species; pathogenic E. histolytica, commensal E. moshkowskii and E. dispar. The aim of the present study was to determine the true prevalence of the E. histolytica using native lugol, trichrome staining and a monoclonal antigen detection kit (ELISA kit E. histolytica-II; Techlab, Inc., Blacksburg, VA) among primary school children living in the rural areas around Sivas.
METHODS
A total of 1449 stool samples were examined by native lugol and Trichrome staining, and 312 (22%) samples were positive for one or more parasite species. Additionally, 22 (1.5%) stool samples were found to be positive for the presence of E. histolytica/dispar cysts, and these samples were further examined by E. histolytica specific antigen based ELISA.
RESULTS
As a result, ELISA test gave negative reactions for all the samples. Also, there was no cross reaction with other luminal protozoa such as E. coli, G. intestinalis, B. hominis and I. butschlii.
CONCLUSION
The data reveals that E. histolytica prevalence may be lower than estimated.
