蓝氏贾第鞭毛虫可引起小肠功能紊乱和组织病变,但其发病机理不明。为此,将鼠小肠粘膜刮落物与感染人体的贾第鞭毛虫滋养体共同孵育,观察其损伤作用。取体重20～25g的4周龄鼠,禁食24小时后剖杀,分段剪开其小肠,以冷生理盐水冲洗后,平铺于冷 Giardia lamblia can cause intestinal dysfunction and histological lesions, but its pathogenesis is unknown. To this end, mouse intestinal mucosal scrapings were incubated with Giardia trophozoites that infect humans to observe their damaging effects. Take a 4-week old rat weighing 20-25 g, fasten it after 24 hours fasting, cut it in small pieces, rinse with cold saline, and spread it on cold
