蓝氏贾第鞭毛虫（简称贾第虫）感染呈世界性分布，为腹泻和营养不良的重要原因。近年来关于宿主对该虫的保护性免疫反应提示，免疫反应在贾第虫感染与发病过程中起着重要作用。因此，研究虫体抗原的组分、作用、变异性及基因调控，对进一步认识保护性免疫机制，建立免疫诊... Giardia lamblia (referred to as Giardia) infection was worldwide distribution of diarrhea and malnutrition, an important reason. In recent years, the host’s protective immune response to the insect suggests that the immune response plays an important role in Giardia infection and pathogenesis. Therefore, the study of the components of parasitic antigen, role, variability and gene regulation, to further understand the protective immune mechanism, the establishment of immunodiagnosis ...
