Mixed saliva and pooled plaque samples from the smooth surfaces of teeth were collected for microbiologic analysis before administration (baseline~ day 0).. during treatment (days 7.. 14 and 21) and after withdrawal of the agents (days 28~ 42 and 56) and plaque index were recorded. Microbial cultivation were performed by serially diluting the samples with PBS solution and cultivating the aiquots on Mitis Salivarius Agar and MS supplemented with bacitracin for Oral streptococci and Mutans streptococci respectively. The plates were incubated at 37~C under microaerophilic condition(90%N2,10%CO.,) for 48 hot:rs. The number of colony-forming unit per plate was counted and the percentage of Mutans Streptococci per Oral streptococci in dental plaque were determined.

Losing competence might affect their β-lactam resistance, and the consequences were different in different strains.4. To further understanding when and where pneumococci formed transformation in vivo so as to study the influence of pneumococcal transformation to its virulence, we constructed a pneumococcus 22G itstransformation forming could be reported by EGFP.

肺炎链球菌的感受态形成可诱导ciaH和cpoA的表达增加，其感受态缺陷影响到其对β-内酰胺类抗生素的敏感性，但不同菌株影响的结果不同。4、为进一步了解肺炎链球菌在宿主体内转化发生的情况，便于深入研究体内细菌转化对其毒力形成的影响，本研究构建了绿色荧光报告细菌转化发生的肺炎链球菌菌株22G。

Results The percentages of the four targeted bacteria in high-caries group were significantly higher than those in caries-free group (P.01), and there was good linear correlation between dmfs index and the sum of the percentages of Streptococcus mutans and Streptococcus sobrinus.

对各组所获数据进行统计学分析。结果高龋组中4种致龋菌所占总菌的比例均高于无龋组(P.01)，其中变异链球菌和无缘链球菌的数量之和所占有总菌的比例与dmfs指数具有良好的线性关系。

MBC value was 0.61, 0.304, and 0.00475 μgmL^(-1) respectively. Sterilization rate of ceftiofur suspension was the fastest to Actinobacillus, followed by Streptococcus. PAE of ceftiofur suspension was relatively short to E. coli, which illustrated that it was nonconcentration dependent. PAE was obvious longer to Actinobacillus, which showed that it was concentration dependent, however, it revealed part concentration dependent to streptococcus.

头孢噻呋混悬剂对大肠杆菌、放线杆菌及猪兽疫链球菌的MIC值分别为：0.076、0.304、0.00475μgmL^(-1)；MBC值分别为：0.61、0.304、0.00475μgmL^(-1)；头孢噻呋混悬剂对放线杆菌的杀菌速率最快，对链球菌次之；头孢噻呋混悬剂对大肠杆菌PAE较短，呈现非浓度依赖性，对放线杆菌的PAE较长，呈明显的浓度依赖性，而对猪兽疫链球菌呈现部分浓度依赖性。

The minimal bactericidal concentration of PTKE on Escherichia coli, Staphylococcus aureus, Salmonella, Pasteurella multocida and Streptococcus agalactiae were 100, 25, 50, 25 and 50 mg/mL respectively. The isolation of EA, EB and EC had no antibacterial effect on Escherichia coli and Pasteurella multocida. MBC of EA on Staphylococcus aureus and Salmonella were 2.5 and 5 mg/mL, and MBC of EB on Staphylococcus aureus, Salmonella and Streptococcus agalactiae were 1.25, 5 and 2.5 mg/mL respectively, while MBC of EC on Staphylococcus aureus was 2.5 mg/mL. Polygonum taibaishanense Kung.

PTKE对大肠埃希菌、金黄色葡萄球菌、沙门氏菌、多杀性巴氏杆菌和无乳链球菌的最低杀菌浓度分别为100，25，50，25和50 mg/mL；而PTKE的分离物EA、EB和EC对大肠埃希菌和巴氏杆菌无抑菌作用，EA对金黄色葡萄球菌、沙门氏菌的MBC分别为2.5和5.0 mg/mL，EB对金黄色葡萄球菌、沙门氏菌和无乳链球菌的MBC分别为1.25，5.0和2.5 mg/mL，EC对金黄色葡萄球菌的MBC为2.5 mg/mL。
