冷应激对雏鹌鹑十二指肠肠道菌群的影响

Effects of cold stress on the intestinal flora in quail duodenum

为探索促进动物冷适应的方法,使动物在寒冷环境中能够保持正常生理机能,在建立雏鹌鹑急、慢性冷应激模型的基础上,应用变性凝胶电泳技术(PCR-DGGE),检测急、慢性冷应激对十二指肠组织肠道菌群的影响.结果表明,急、慢性冷应激均可以导致雏鹌鹑十二指肠内肠道微生物数量和种类的改变.冷应激会引起雏鹌鹑肠道生物屏障功能受损.

In order to explore the method of promoting animal cold adaptation,and enable animals can maintain normal physiology in cold environment,this study was built cold stress model of quails,using the PCR-DGGE method to detect the change of intestinal microflora in quail duodenum which induced by acute and chronic cold stress groups. The results showed that both acute and chronic cold stress could cause changes in the number and types of intestinal microbiota in the duodenum. It concluded that cold stress could lead to impaire intestinal biologic barrier function.
