Abstract
The evolutionary spread of schistosomes infection was reportedly prominent more in Africa
and Asia continents. This study therefore examined the evolutionary trend of this parasite
while limiting the investigation to Schistosoma species peculiar to this region of the world.
The evolutionary history of this species group was inferred using DNA sequences from
NCBI Genbank database and Maximum likelihood, Ancestral inference; Neighbor-Joining
method analysis was employed in this study. All members of this species complex were AT
rich, with S. mekongi and S. malayensis having the highest AT nucleotide composition. The
smallest evolutionary divergence was also observed in S. curassoni and S. bovis. The
finding of this study slightly contradict previous report on ancestral prediction of
Schistosomes.
