Table 1.
Total number (n) and percentage (%) of the six possible cox1-ITS2 genetic profiles identified using the haploid mitochondrial cox1 gene (first two letters) and the diploid nuclear ITS2 region (last four letters), i.e. “pure” Schistosoma haematobium (S. haematobium cox1 × S. haematobium ITS2: Sh × ShSh), S. bovis genetic signature (S. bovis cox1 × S. bovis ITS2: Sb × SbSb) and four types of hybrid (S. bovis cox1 × S. haematobium ITS2_S. bovis ITS2: Sb × ShSb; S. bovis cox1 × S. haematobium ITS2: Sb × ShSh; S. haematobium cox1 × S. bovis ITS2: Sh × SbSb; S. haematobium cox1 × S. bovis ITS2_ S. haematobium ITS2: Sh × ShSb) per area. Total number (percentage in parentheses) of S. bovis (Sb) and S. haematobium (Sh) cox1 haplotype and ITS2 alleles per site.
