Fasciolosis is caused by Fasciola hepatica with Lymnaea spp. as intermediate hosts.  Lymnaea arabica, as a possible snail host collected from the Kingdom of Saudi Arabia, was investigated by Random Amplified Polymorphic DNA polymerase chain reaction (RAPD-PCR) technique. Polymorphic bands from L. arabica were sought for fingerprinting (typing) and identification of this species. The resultant electrophoretic patterns  would be used as molecular bio-markers for thesemolluscas. This will help in the identification of the snails at a molecular level for the first time in the country that, in turn, will help in disease control. This technique was proved to be an accurate, appropriate, efficient and valuable alternative to traditional identification tools of Lymnea spp.
