The pathological basis of schistosomiasis is that the host has an immune response to the soluble antigen (SEA) released by the mature eggs in the tissue. Both cellular immunity and humoral immunity are involved in the process. The main cellular immunity is CD4 + cells and secreted cytokines Important role. Immune reactions cause the formation of granulomas and the deposition of collagen in the liver resulting in hepatic fibrosis. In addition, the eggs caused by the anterior sinus obstruction cited
