These authors examined, in mice, the role of colonization with the human commensal bacterium Bacteroides fragilis on the immune response to challenge with Helicobacter hepaticus.

这些结果表明菌群分子可调解健康与疾病之间的重要平衡。基于全新的生物界原则，利用共生因子如PSA的免疫调节能力可能将为人类炎症疾病的治疗提供方法。

We gained the Buchnera groEL gene of Schizaphis graminum, and Rhopalosiphummaize biotype through this study , and have done a primary study of expression. Based on this study, we can further probe the role during aphid transmission of Buchnera GroEL and utilize them through the ways of genetic engineering.

蚜虫内共生菌Buchnera groEL基因的获得、初步的原核表达研究以及GroEL蛋白抗血清的制备，为进一步研究GroEL蛋白在蚜虫传毒中的作用方式和位点以及在基因工程途径的利用打下了基础。

The relationship between aphid arid Buchnera is a typical mutualism.

蚜虫-巴克纳氏菌之间是一种典型的互利共生关系，两者相互依存，缺少一方，另一方便不能生存。

To further explore the phylogenetic relationships between the aphid Myzus persicae and its endosymbiotic bacterium Buchnera, COⅠ/COⅡ, 12S/16S rRNA and EF-l alpha genes in four populations of M. persicae were amplified. Through phylogenetic trees constructed by the COⅠ/COⅡ, 12S/16S rRNA and EF-l alpha genes in M.

为进一步明确桃蚜与其内共生菌Buchnera之间系统进化关系，参照前人研究蚜虫系统进化所用的COⅠ/COⅡ、12S/16S rRNA、EF-1 alpha的3对引物，对桃蚜的COⅠ/COⅡ、12S/16S rRNA、EF-1 alpha基因进行了扩增，并构建了桃蚜COⅠ/COⅡ、12S/16S rRNA、EF-1 alpha基因序列系统进化树。
