Hybridisation between the digeneans Schistosoma haematobium and S. mattheei : viability of hybrids and their development in sheep
The F1 and F2 hybrids of Schistosoma haematobium male × S. mattheei female were studied with regard to infectivity to intermediate and definitive hosts, isoenzymes (phosphoglucomutase) of individual
Enzyme analysis of Schistosoma haematobium.
TLDR
Results are reported of enzyme analyses, by isoelectric focusing in polyacrylamide gels, of adult Schistosoma haematobium worms derived from 22 isolates originating from 13 countries, suggesting human population movements resulting in mixing of parasite strains.
Frequency and possible consequences of hybridization between Schistosoma haematobium and S. mattheei in the Eastern Transvaal Lowveld
TLDR
It is highly unlikely that the two species of Schistosoma mattheei and S. haematobium will evolve into a single species, and it seems that the virulence of the parental species will be influenced.
Enzyme polymorphism in Schistosoma mattheei from cattle in the Eastern Transvaal Lowveld
TLDR
Enzyme electrophoresis was conducted on 10 Schistosoma mattheei adult worm samples, comprising 270 individuals, collected from cattle in the Eastern Transvaal Lowveld, finding that PGM was monomorphic in all the populations studied and MDH-1 exhibited two alleles that were not in equilibrium.
Natural Interactions between S. haematobium and S. guineensis in the Republic of Benin
TLDR
The results provide the first evidence of introgression of S. guineensis genes in S. haematobium in Benin and any natural interaction between these two species of schistosomes is detected.
Isozyme patterns of Schistosoma japonicum and S. mansoni
TLDR
Results suggest that S. japonicum is clearly distinguishable from S. mansoni at the molecular level, indicating that electrophoretic patterns from parasite extracts are most probably of parasite origin.
Biological and biochemical comparative studies on Schistosoma mansoni from two localities in Egypt where S. haematobium is endemic.
TLDR
Observations about the changing pattern of Schistosoma mansoni and S. haematobium distribution in Egypt are better explained by the phenomenon of parthenogenesis than by the production of true genetic hybrids.
Bidirectional Introgressive Hybridization between a Cattle and Human Schistosome Species
Schistosomiasis is a disease of great medical and veterinary importance in tropical and subtropical regions, caused by parasitic flatworms of the genus Schistosoma (subclass Digenea). Following major
On Schistosoma curassoni, S. haematobium and S. bovis from Senegal: development in Mesocricetus auratus, compatibility with species of Bulinus and their enzymes
A comparative study on the development of Senegalese isolates of Schistosoma curassoni, S. haematobium and S. bovis in hamsters is reported, together with the compatibility of these parasites with
Cattle schistosomiasis in Zambia
TLDR
W worms collected from 104 infected individuals was examined for glucose-6-phosphate dehydrogenase and phosphoglucomutase using isoelectric focusing and showed one of two distinct heterozygote patterns, identical to that of a laboratory-produced Fl S. mattheei × S. leiperi hybrid.

Hybridisation Experiments on Five Species of African Schistosomes
TLDR
There are clear biological differences in definitive and intermediate host specificity and in parasitic site within the host, and these criteria serve to strengthen a classification based on egg morphology.

TLDR
The safety and efficacy of oxamniquine against Schistosoma mansoni at an oral dose of 15mg/kg twice a day for 2 days (total dose 60 mg/kg), were confirmed and no detectable effect was noted against S. haematobium or S. mattheei.
