Research Abstract |
Intermediate subunit of Gal/GalNAc lectin (Igl) located on the surface of Entamoeba histolytica trophozoites is involved in amebic adherence to host cells. When genetic diversity of two Igl genes was analyzed in 22 isolates of E. histolytica, Igl1 and Igl2 genes were divided into 5 and 2 types, respectively. Since seven types of combination between Igl1 and Igl2 were observed, occurrence of recombination between the two loci was suggested. Polymorphism of two Igl genes was also observed in E. dispar and E. nuttalli isolates.
