Schistosoma haematobium?

While I agree with the previous comment considering the site of the infection the geographic location and curled leaf cross section, my other question is that the colorless ovoid objects are they the calcified eggs of the fluke?

Agree with the first comment - S. haematobium. Urogenital infection and geographic location would support this species as well.

Pretty sure I can spot a few eggs - judging by size and location. Perhaps if this is S haematobium Bobbi can show us in the reveal if eggs are present.

I also agree with Schistosoma. Looking at site of infection and geography, most probably S. haematobium. Section shows adult fluke and numerous non-calcified viable eggs (because I can see the cephalic gland, surrounded by nerve cells - a bautifull bullseye). In some eggs I seem to discern a small terminal spine, which supports S. haematobium.
