Methods The clpE-deficient strain was constructed by LFH-PCR and identified by PCR and sequencing. The impact of clpE mutant on the virulence of S. pneumoniae was evaluated in a mouse model. In addition, we also studied the effect of clpE mutant on adherence and invasion of host cells. Real time RT-PCR was used to measure the mRNA expression levels of autolysin A, pneumococcal surface adhesion A, pneumolysin, pneumococcal surface protein A and neuraminidase The clpE gene was replaced completely by erm cassette.
用长臂同源多聚酶链式反应方法失活clpE基因,用PCR、测序鉴定缺失菌株,通过动物实验观察clpE基因缺失株毒力改变情况,同时用细胞实验比较clpE基因缺失株和野生菌对宿主细胞的粘附和侵袭能力,最后用实时荧光定量PCR分析自溶素(major autolysin A,lytA)、表面黏附素A(pneumococcal surface adhesion A,psaA)、溶血素(pneumolysin,ply)、肺炎球菌表面蛋白A(pneumococcal surface protein A, pspA和神经氨酸酶(neuraminidase, nanA)的表达。
