Characterization of YS-27, an axenic Korean strain of Entamoeba histolytica

Abstract

Characterization of YS-27, an axenic Entamoeba strain, was performed by three different laboratory methods. Zymodeme analysis using starch gel electrophoresis and PCR with species-specific primers showed that YS-27 is a pathogenic Entamoeba which belongs to the group II zymodeme. Pathogenicity of YS-27 was further confirmed by observing the formation of liver abscess in Mongolian gerbils. These results showed that YS-27 is E. hisolytica.
