Life cycle of S. haematobium. S. haematobium completes its life cycle in humans, as definitive hosts, and freshwater snails, as intermediate hosts, just like other schistosomes. But unlike other schistosomes that release eggs in the intestine, it releases its eggs in the urinary tract, which are excreted along with the urine. [15]
Individuals infected with Schistosoma release eggs into water via their feces or urine. A collection of stool samples under a microscope will show the eggs of S. intercalatum, S. mansori, and S. japonicum. Looking at a urine sample under a microscope would reveal the eggs of S. haematobium and rarely, the eggs of S. mansori. [38]
