The life cycle stages: [43] The excretion of schistosome eggs in urine or feces depending on the species; The hatching of the eggs leads to the release of the free-swimming, ciliated larvae called miracidia; Miracidia find and penetrate the snails, which are the intermediate hosts (specific species of snails are dependent on the species of ...
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 ]

Schistosoma is a genus of trematodes, commonly known as blood flukes. They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis , which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria ), infecting ...
It has also shown that the spirorchiids are the closest relations of the schistosoma. An outline of the evolution of the schistosoma is now possible. The ancestral species infected freshwater turtles and the life cycle included gastropod hosts. Some of these species in their turn infected the marine turtles. [3]
Schistosoma life cycle. Schistosoma bovis infects two hosts, namely ruminants (cattle, goats, sheep, horses and camels) and freshwater snails (Bulinus sp. and Planorbarius sp.). [15]: 392 Experimental infections have been proven in Planorbarius metidjensis snails, which are native to Northwestern Africa and the Iberian peninsula. [citation needed]
A paired couple of Schistosoma mansoni. Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels (mesenteric veins) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum, S. mekongi, S. guineensis, and S. intercalatum ...
Schistosoma hippopotami is a species of digenetic trematode that belongs to the genus of blood flukes (Schistosoma) that is found in sub-Saharan Africa. [1] It primarily infects African hippopotamuses ( Hippopotamus anphibius ) and has a more limited host range compared to other Schistosoma species.
