摘要: 目的研究结核分枝杆菌Ag85A/B嵌合DNA疫苗治疗小鼠敏感结核病的效果。方法用结核分枝杆菌标准株H37Rv尾静脉注射50只雌性BALB/c小鼠后,将小鼠随机均匀地分为5组,感染后第3 d开始,分别用生理盐水(A组)、pVAX1载体(B组)、利福平(C组)、草分枝杆菌F.U.36注射液(D组)、Ag85A/B嵌合DNA疫苗(E组)治疗,每2周肌肉注射1次DNA疫苗,共3次。在治疗结束后2周,杀鼠,取小鼠肺和脾观察病理改变、称取重量、做菌落计数。结果与A组比较,D组、E组肺脏病变有不同程度减轻,病变局限,3/5区域肺泡结构完整,清晰,细胞分布均匀。与A组相比,C、D、E组肺脏菌落数依次减少2.11 log、0.76 log、0.81 log|肝脏菌落数依次减少2.11 log、0.74 log、1.11 logs(P<0.01)。结论 Ag85A/B嵌合DNA对小鼠敏感结核病具有较好的治疗效果。

Abstract: Objective To evaluate the therapeutic effect of Ag85A/B chimeric plasmid DNA vaccine in the mouse model infected by M.tuberculosis to establish a new immunotherapeutic agent against the tuberculosis.Methods 50 female BALB/c mice were infected intravenously via the tail vein with 68000 CFU of M.tuberculosis H37Rv,then randomly divided into 5 groups,and treated as follow at the third day after infection:group A,saline|group B,plasmid vector|group C,rifampin|group D,Mycobacterium phlei F.U.36 injection|group E...
