Fig 1.
Egg morphologies of the pure parental species and the European S. haematobium-bovis hybrids.
Eggs 1 and 2 show typical morphologies of S. haematobium (elliptical with a terminal spine) and S. bovis (spindle shape with a terminal spine), respectively from laboratory isolates. Eggs 3–9 show the egg morphology of the European S. haematobium-bovis hybrid schistosome. While most eggs were of a typical S. haematobium morphotype (3–7), there was a high variability in the morphologies and near 10% (4/44) of eggs were non-typical (8–9).
