一般说来,在寄生虫病,免疫产生很慢,而且须伴有活虫的持续存在。这与许多细菌性和病毒性疾病获得的免疫不同。由于这种原因,在寄生虫病,包括血吸虫病,免疫预防方法的可能建立有赖于详细研究宿主的免疫反应。在实际可行的方法能够找到以前,如免疫预防,减轻免疫病理的病变,以及改进免疫诊断,需要做很多基础研究。 In general, in the case of parasitic diseases, the immune system is very slow and must be accompanied by the persistence of living insects. This is different from the immunity acquired by many bacterial and viral diseases. For this reason, the possible establishment of immunoprophylaxis in parasitic diseases, including schistosomiasis, depends on a detailed study of the host’s immune response. Much basic research needs to be done before practical approaches can be found, such as immunoprophylaxis, lessening the pathology of immunopathology, and improving immunodiagnosis.
