Misleading inference of schistosome epidemiology from ribosomal internal transcribed spacer (ITS) and mitochondrial DNA

E.E. Enabuele, Roy N. Platt, Ehizogie Egbeobauwaye Adeyemi…·Tim Anderson

Whole-genome SNVs from Nigerian schistosomes show cox1/ITS genotyping wrongly flags human-derived parasites as recent hybrids or zoonotic infections; they are S. haematobium with low livestock introgression.

Genomic data reveal a north-south split and introgression history of blood fluke (Schistosoma haematobium) populations from across Africa

Roy N. Platt, Egie Elisha Enabulele, Ehizogie Egbeobauwaye Adeyemi…·Timothy J. C. Anderson

The paper analyzes genomic data from Schistosoma haematobium populations across Africa, revealing a north-south genetic split and ancient introgression events with S. bovis, with some genes approaching fixation and sex chromosomes showing introgression resistance.
