Parasite ( Schistosoma mansoni ) and host ( Biomphalaria glabrata ) genetic diversity: population structure in a fragmented landscape
Random amplified polymorphic DNA (RAPD) markers were used to quantify genetic diversity within and between 5 populations of Schistosoma mansoni within its definitive host ( Rattus rattus ) and the 5 corresponding populations of the snail intermediate host ( Biomphalaria glabrata ) from a limited end...

Random amplified polymorphic DNA (RAPD) markers were used to quantify genetic diversity within and between 5 populations of Schistosoma mansoni within its definitive host ( Rattus rattus ) and the 5 corresponding populations of the snail intermediate host ( Biomphalaria glabrata ) from a limited endemic area of murine schistosomiasis on the island of Guadeloupe.

Geographical localities accounted for 20.5% (CCA) of the total diversity for B. glabrata populations. The genetic distances between pairs of parasite populations were not correlated with the genetic distances between the corresponding pairs of snail host populations. Such strong patterns of local differentiation of both parasite and snail populations are consistent with predictions based on metapopulation dynamics and may have implications on host–parasite susceptibility relationship through local adaptation processes. |
