- Virulence pattern of E. histolytica could be linked with the genotype of a strain.
- SINE1/2 elements can provide a simple PCR-based tool to genotype clinical isolates.
- Locus 17 of EhSINE1as a potential geographical marker for distinguishing Indian isolates from non Indian isolates.
Entamoeba histolytica is an intestinal parasite causing significant morbidity and mortality in the developing world. More tools are needed to understand the epidemiology and molecular pathogenesis of amebiasis. Virulence pattern of E. histolytica could be linked with the genotype of a strain. Several loci showing insertion polymorphism of retrotransposable short interspersed nuclear elements EhSINE1 and EhSINE2 have been reported among laboratory strains of E. histolytica. The present study was undertaken to validate this observation in clinical isolates from north India. Our results indicate that the Indian samples show a different propensity of SINE retention or loss at two of the polymorphic loci compared with non-Indian samples. Statistical analysis of different loci revealed Locus 17 of EhSINE1as a potential geographical marker for distinguishing Indian isolates from non Indian isolates.
