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。

On the other hand, the protein also showed selective bactericidal activity. Among the tested strains, Escherichia coli is the most sensitive to the protein, Klebsiella pneumoniae is the second, and Bacillus subtilis is the least sensitive to the putative endolysin.

另外，此蛋白质的杀菌效力具有选择性，受测菌株中，对於大肠杆菌的杀菌效力最佳，其次为克雷伯氏肺炎杆菌，对於枯草杆菌效果较差。

But Streptococcus suis type 2 often combined infectionwith some other etiological agents as Actinobacillus suis, Bacillus erysipelatous andPRRS virus, It results in tremendous difficulty by clinical diagnosis and antibodiesdetection.

但猪链球菌经常与其他一些病原如猪放线杆菌、猪丹毒杆菌和猪蓝耳病病毒等发生混合感染，给临床诊断和抗体水平的检测造成了很大困难。

A bacteriocin-like substance producing strain T12 was screened from 212 lactic acid bacteria isolated from intestine of healthy pigs by paper disk test and was identified as Lactobacillus. The supernatant of T12 exhibited strong inhibitory activity against the gram-positive bacteria, including Micrococcus lysodeikticus, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. A strong activity was also observed against the gram–negative bacteria and some eumycete, such as Escherichia coli, Salmonella typhimurium and Fusarium graminearum.

通过滤纸片法从健康肉猪猪大肠、小肠中分离得到212株抗生物质产生菌，以杯碟法复筛，得到1株对溶壁微球菌、金黄色葡萄球菌、枯草芽孢杆菌、蜡状芽孢杆菌等革兰氏阳性菌和大肠杆菌、鼠伤寒沙门氏菌等革兰氏阴性菌以及部分真菌如禾谷镰刀霉均有强烈抑制作用的乳酸菌。

To study the effecacy of heat clearing and Qi regulating prescriptionfor helicobacter felis gastritis in Balb/c mice,sixty model Balb/c mice were randomly allocated to five groups:three HCQRP groups(in 26.6g/kg,13.3g/kg and 6.65g/kg respectively) and triple therapy control group(with metronidazole,tetracycline and bismuth)and saline control group.

为检验清热理气方(蒲公英60g、黄连10g、黄芩10g、枳壳10g、佛手12g、炙甘草6g)对实验性猫胃螺杆菌胃炎的治疗作用。采用复制Balb/c猫胃螺杆菌胃炎模型，以清热理气方大、中、小剂量(分别为26.6g/kg、13.3g/kg、6.65g/kg)给药，以三联疗法(灭滴灵2.6mg、四环素1.3mg、丽珠得乐1.3mg)为阳性对照组，以生理盐水为阴性对照。

The mixture of 50% non-fat milk power and 50% starch is the more effective and cheaper carrier. The concentration of Lactobacillus fermentum and Lactobacillus plantrum is 1. 21 X 1010 cfu/g , 9. 84 X 109 cfu/g in powder starter with glycerol added and the cell survival is still 65.2% and 69. 1%.respectively, after 90 days storage.

对用于制备干粉发酵剂的载体和保护剂进行了筛选，结果显示用含脱脂奶粉和淀粉各半的混合物作载体、用甘油作保护剂制备乳酸菌干粉发酵剂效果较好，发酵乳杆菌和植物乳杆菌的活细胞数分别可以达到1.21×10~(10)cfu·g~(-1)、9.84×10~9cfu·g~(-1)，保藏90天后，细胞存活率为65.2％、69.1％。
