The internal transcribed sequence and 18S single nucleotide polymorphisms discriminating the three Schistosoma species and the hybrid forms
| SNP and Schistosoma species | DNA region | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| ITS | 18S | |||||||||
| SNP position | 51 | 703 | 758 | 808 | 878 | 225 | 250 | 297 | 685 | 1184 |
| S. haematobium | A | G | C | G | C | T | C | T | T | A |
| S. bovis | G | A | T | A | T | C | T | C | C | G |
| S. curassoni | A | A | T | A | T | T | T | T | T | G |
Hybrids can be observed to have alleles from both species in the combination, but this depends on the hybrid generation and the DNA marker being used
The SNPs targeted by the ITS and 18S T-ARMS-PCRs are shown in italics
