Abstract

Objective: In this study, we aimed to research the frequency of intestinal amebiasis in patients who applied with diarrhea retrospectively for a year and compare direct microscopic analysis and ELISA adhesin antigen test for Entamoeba histolytica procedures.

 

Methods: The fecal matter sample of 259 patients with diarrhea who applied to the Sivas Numune Hospital Microbiology Laboratory between February 2012 and March 2013 were studied. Samples were evaluated with direct microscopic analysis and Entamoeba histolytica adhesin antigen test (E. histolytica II, Techlab,  Blacksburg, USA).

 

Results: In the patients who applied to our laboratory with an amebiasis diagnosis, the mean age was detected as 40.12±19, and the positivity range of the Entamoeba histolytica adhesin antigen test was detected as 25.1% (n=65). In ELISA adhesin test-positive patients 24.6% (n=16) trophozoites, cyst, abundant leukocytes and erythrocytes were detected, and in 6 patients (3.1%), ELISA adhesin antigen test was negative. There was no difference between males and females (p>0.05), but between-season difference was detected (p<0.05).

 

Conclusion: Direct microscopic analysis may be inadequate in the differential diagnosis of E. histolytica/ and E. dispar and discrimination of Entamoeba cyst and/or trophozoites from other cellular elements (esp. leukocytes). Furthermore, we thought that the E. histolytica monoclonal ELISA adhesin test is useful for the differential diagnosis of pathogenic E. histolytica and nonpathogenic E. dispar.
