Cellular immune response and pathology in schistosomiasis.
In the present review, some aspects of the cellular response following the murine Schistosoma mansoni infection are described. Due to the peculiar route used by the schistosome to infect its definitive host, the skin appears as a critical site in which the initial events of the host/parasite relationship occur and where the immune response is initiated. Moreover, the induction and the modulatio...

By A.D. 1969 the world incidence of schistosomiasis was at least 150 mi...
متن کاملImmunology of human schistosomiasis
There is a wealth of immunologic studies that have been carried out in experimental and human schistosomiasis that can be classified into three main areas: immunopathogenesis, resistance to reinfection and diagnostics. It is clear that the bulk of, if not all, morbidity due to human schistosomiasis results from immune-response-based inflammation against eggs lodged in the body, either as regula...
متن کاملThe impact of schistosomiasis on the pathology of bladder carcinoma.
In a series of 1095 Egyptian patients with carcinoma of the bladder treated by radical cystectomy, 902 cases (82.4%) contained schistosome eggs in the specimens, and 193 (17.6%) were egg-negative. The different tumor parameters were compared in these subgroups to explore any differences that could be related to schistosomal infestation. In egg-positive cases, the tumor developed at a younger ag...
