Liver function test can be ordered if hepatosplenic schistosomiasis is suspected, and a subsequent hepatitis test panel can be ordered if liver function test is abnormal. [ 19 ] Like most parasitic infections, schistosomiasis will usually cause significant eosinophilia that can be identified on a complete blood count with differential.
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 ...

Schistosoma intercalatum's life cycle is very similar to that of S. haematobium, except for some key differences. To start the life cycle, the human host releases eggs with its feces. In water, the eggs hatch to become miracidia, which penetrate the freshwater snail intermediate host. [5]
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]
The life cycle begins with parasitic eggs growing in freshwater. Larvae called miracidia hatch from the parasitic eggs and go seek out the intermediate host, the freshwater snail. [ 13 ] For each of the different species of Schistosoma , the intermediate and primary hosts are different.
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 ...
