| Objective:To analyze the distribution diversity of intestinal flora and detect the dominant bacteria in normal Savda
Hilits people of Uighur nationality.Methods:Healthy savda hilit were chosen by Uighur medicine and stool samples were collected from
these groups. Then the total DNA was extracted, a pair of universal primers were designed to amplify the 16S rDNA V6 to V8 variable
regions. Denaturing gradient gel electrophoresis (DGGE) of amplified sequences was performed, then the DGGE bands and sequencing
was cloned.Results:The DNA fingerprinting reflecting the structural features of intestinal flora was obtained, some specific band sequencing
were selected and cut from fingerprinting, the detected gene sequence was compared with the Genebank database on the Blast
program, and make the evolutionary tree understanding of the relationship between intestinal microflora.Conclusion:Normal savda Hilit
gut microbial gene sequence showed savda Hilit intestinal bacteria had rich diversity and the savda hilit gut microbial Lactobacillus
(GU269544.1) had a height advantage. |
