Schistosoma Haematobium and Urogenital Disorders: (OAJRSD)- Lupine Publishers

Schistosoma Haematobium and Urogenital Disorders by Maria Amélia A Grácio in Open Access Journal of Reproductive System and Sexual Disorders in Lupine Publishers

Concerning Europe, we are in the presence of a re-introduction of this disease, since it had been recorded in Portugal, where several foci had occurred in Algarve-Southern Portugal [2,3] Still in Europe, the record of new localization of intermediate hosts of S. haematobium can be a risk of expansion of this parasite in European continent [4,5]. S. haematobium is a blood fluke and part of its development occurs within freshwater snails (intermediate hosts) and the diseases is contracted when cercariae larvae (infectant stage for humans) are liberated from the snails and penetrate the skin of anyone that is in contact with infected water (bath, domestic activities, fishing, etc.,). The cercariae, after penetration are known as schistosomulae. These migrate and develop into mature adult schistosoma worms, their habitat being inside blood vessels. Then, the adults inhabit the veins of the vesical plexus, although some parasites may live in the portal vein and its mesenteric branches. Oviposition normally occurs in the small terminal venules of the vesical plexus, but occasionally in the rectal venules, the mesenteric portal system and ectopic sites. Ectopic migration of the S. haematobium adults and Oviposition can occur anywhere in the body, resulting in a variety of lesions.
