This work might lead to develop many better methods or means of preventing and controlling dysenteric diarrhea.To elucidate the role of H-NS protein in bacterial physiology, the hns gene insertion and deletion mutants were constructed with RecA and Red recombination system. Then, growth curve and invasion ability of wild strain and deletion mutant were studied.

为了更深入的了解hns基因在细菌生命活动中所起的作用，我们首先利用RecA重组系统构建了痢疾杆菌2457T hns基因的插入突变体；随后，对基于Red重组系统的痢疾杆菌2457T缺失突变体的构建方法进行了摸索并成功地敲除了hns、hdeA、hdeB、yhiE和yhiF 5个基因，研究表明延长同源臂的长度可以明显提高同源重组的效率，缩短构建缺失突变体所需的时间。
