Introduction. Schistosomiasis is a parasitic infection caused by trematode worms that are known to cause either acute infection (known as Katayama syndrome) or chronic infection, which primarily results from the host's immune response to schistosome eggs and the granulomatous reaction provoked by their antigens [1, 2].Schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH) is a. Schistosomiasis. Schistosoma mansoni is a fluke that can colonize pelvic veins. Adult organisms within abdominopelvic veins can involve surrounding visceral or cutaneous tissue with a granulomatous reaction. Eggs are typically conducted to the bladder lumen and are excreted during micturition. Sinuses, fistulas, and masses may be present BAKGRUND Schistosomiasis, snäckfeber, kallas ibland bilharzios efter den tyske parasitologen Bilharz, som upptäckte och beskrev S. haematobium-infektionen i Kairo 1851.
