Host - Parasite Relationships Between Schistosoma Mansoni and Echinostoma liei and their Intermediate Host Biomphalaria Alexandrina using RAPD - PCR Analysis

ABSTRACT

The aim of this study was to use RAPD-PCR assay offering an alternative approach to host-parasite relationships. This was performed by investigating the genetic variation and compatibility among S. mansoni, E. liei and their intermediate host B. Alexandrina with a special emphasis on the variations occurring in snails infected with S. mansoni and/or E. Liei. Six primers were screened for DNA analysis and gave total patterns from 28-37 reproducible bands for each species. All specimens analyzed by the RAPD-PCR gave interpretable electrophoretic banding patterns that were polymorphic and compatible in the amplified products of these primers within each species
