Nigeria, Molecular, Radix, Characterization


Radix (Lymnaea) natalensis (Krauss, 1848) is an essential host in the completion of the life cycle of Fasciola gigantica especially in large areas of Africa, where it is reputed to serve as the main, if not the only intermediate of Fasciola. In this study, 18S rDNA gene was employed for the molecular characterization of morphologically identified Radix natalensis collected from Nigerian Northern cities of Gombe and Jos. The obtained result revealed that the amplification of the 18SrDNA gene at 450bp identified and confirmed the collected species as Radix natalensis. BLASTn search showed that sequences of Nigerian isolates of Radix natalensis had high (99-100%) degree of similarities with each other and with other sequence deposits in the NCBI GenBank. The Nigerian sequences on phylogenetic analysis formed a separate clade distinct from other sequences of Radix natalensis from other parts of Africa and the rest of the world, suggestive of clustering based on geographical location. Thus, the availability and confirmation of Radix (Lymnaea) natalensis from the study locations as evidenced by the results of this study further justifies the assertion of Lymnaea natalensis, being a putative intermediate host of Fasciola spp. in Nigeria.
