| Sumario: | The I S. haematobium cox1 i data from all samples matched the common H1 haplotypes found across mainland Africa.[7] The I cox1 i data from the bladder biopsy identified both I S. bovis i and I S. haematobium i mitochondrial DNA. Keywords: ITS2; cox1; Schistosoma hybrid; phylogenetic analysis EN ITS2 cox1 Schistosoma hybrid phylogenetic analysis 1 3 3 11/09/22 20221001 NES 221001 Schistosomiasis is a neglected tropical disease affecting up to 90% of people living in Africa.[1] The emergence of natural inter I Schistosoma i species hybrids clearly highlights potential risks of mixing between human and animal infections, enhancing transmission and the spread of new strains.[2] In particular, I Schistosoma haematobium i and I Schistosoma bovis i are closely related, are known to hybridize and also share snail intermediate hosts of the genus I Bulinus i .[3] The I S. haematobium-bovis i hybrid diagnosis in patients plays an important role in explaining unusual morbidities and disease outcomes together with the potential risk of introduction into non-endemic areas I . i [2],[4] Herein, to identify the potential presence of I S. haematobium-bovis i hybrids, we molecularly characterized typical and atypical eggs, presumed to be I S. haematobium i , collected from young African migrants.
