Schistosomiasis haematobium



(pathology) Schistosomiasis that is particularly caused by Schistosoma haemotobium infestation, and afflicts mainly the urinary tract of the definitive host, and endemic in Africa, parts of the Middle East, and the southern Europe


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 haematobium is a schistosomiasis caused particularly by Schistosoma haematobium. It makes use of Bulinus spp. And Physopsis spp. (snail species) as its intermediate host. Upon reaching the cercaria stage, the worm leaves the snail to enter the skin of the definitive host, such as mammals (including humans). It transforms into a schistosomulum and spread via the bloodstream. It feeds on the host's blood and grows into adult form. From the liver, the worms travel to the bladder (venus plexus) where the female begins to produce eggs.1
