Objective:

Entamoeba histolytica is indistinguishable from Entamoeba dispar in direct microscopic examination. A definitive diagnosis of E. histolytica is important in terms of the treatment of the patient and to avoid unnecessary costs. This study’s aim is to determine the prevalence of E. histolytica and to make a comparison of the different diagnostic tests in the patients specimens defined as E. histolytica/E. dispar infection.

Materials and Methods:

Faecal and serum specimens of 90 patients defined as E. histolytica/E. dispar with microscopy (wet mount examination with 0.85% saline and Lugol’s iodine) were examined. Stool samples were examined by trichrome staining for trophozoites and cysts and by immunoassay methods for specific adhesin antigens (Wampole® E. histolytica II antigen testing) and for specific serine-rich 30 kD membrane protein (Serazym® E. histolytica antigen testing). Anti-E. histolytica …
