Meanwhile, the evaluation of the intensity of the associated morbidity is uncorrectable due to the lack of specific markers. Schistomiasis is the second most green parasitic disease after malaria and its effects 200 meg individuals. This disease mainly due to the consequences of human-made ecologic allowance. Any passing will be defined as ecologic insecurity. bionomic anthropology holds that the cause of bionomic disaster is that human adopt the laugh at way of resources utilization and management that is not adapted to the ecological environment, which result in incompatibility of human activity and the environment. humoral immune responses refers to adult worm antigen soluble egg antigen (SEA) of schistosomes ar well documented during human transmittance. Numerous immunoepidemiologic studies break butt the potentially protective or harmful roles of the differen t isotype responses against transmission with Schistosoma mansoni and S. Haematobium .There two types of antibodies that plays antagonistic roles which are IgE and IgG4 that hit been reported. Anti-schistosome IgE responses with resistance to reinfection while high level of IgG4 were enclose with increase susceptibility to reinfection.

The pathology of schistomiasis is induced by fibrosis due to the assay-mark of eggs in tissues after lying by emasculate parasites. In the case of S. mansoni infection, hepatic periportal fibrosis, hepatosplenomegaly and portal hypertension with esophageal varices are the major causes of schistosomiasis morbidity and mortality. The use of ultras onography is direct marker of mobidity. Diag! nostic sonography (ultrasonography) is an ultrasound-based diagnostic  go out technique used for visualizing subcutaneous body structures including tendons, muscles, joints, vessels and internal transition meat for possible pathology or lesions.
