Comparison of use of enzyme-linked immunosorbent assay-based kits and PCR amplification of rRNA genes for simultaneous detection of Entamoeba histolytica and E. dispar

Abstract

A comparison of the use of three commercially available enzyme-linked immunosorbent assay-based kits and PCR amplification of rRNA genes to detect and differentiate Entamoeba histolytica from E. dispar was carried out. Only the Techlab kit did not cross-react with E. dispar antigens, but it was 100 times less sensitive than PCR in detection of and differentiation between the two types of Entamoeba.
