(pathology) Schistosomiasis that is particularly caused by Schistosoma mansoni infestation that affects mainly the bowel, spleen, and liver, and is endemic in Africa, the Middle East, South America, and the Caribbean
Schistosomiasis is a disease that results from schistosome infestation. Schistosomes are trematode worms and are parasites that inhabit the urinary or mesenteric blood vessels of their definitive hosts. The signs and symptoms include poor growth, bloody stool or urine, abdominal pain, and diarrhea. The possible complications of the disease include infertility, kidney failure, liver damage, squamous cell carcinoma, etc. There are many forms of schistosomiasis based on the species causing the disease: schistosomiasis japonicum, schistosomiasis haematobium, schistosomiasis intercalatum, schistosomiasis mansoni, and schistosomiasis mekongi.
Schsitosomiasis mansoni is a schistosomiasis caused particularly by Schistosoma mansoni. It is endemic in Africa and South America, particularly Brazil, Venezuela, Surinam, and Guyana. The infestation with this schistosome species may lead to rashes, fever, muscle aches, bladder cancer, damaged organs, etc.1 The eggs of the schistosomes may incite an immune reaction that could lead to liver inflammation and enlargement. Katayama fever is a form of fever associated with the onset of egg laying of schistosomes.
