Embodiment Construction

[0113] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the present invention is not limited to the following embodiments. The materials used in the examples are the feces of a group of patients confirmed to be positive for Clostridium difficile AB toxin provided by the General Hospital of Guangzhou Military Region.

[0114] The specific steps of the experimental process for establishing the library of the present invention are as follows.

[0115] 1. Extract the total genomic DNA of fecal flora:

[0116]The total genomic DNA of the fecal flora was extracted strictly according to the operation manual of the TIANamp Stool DNA Kit (TIANGEN DP328), and the conditions were optimized for intestinal bacteria: the lysis temperature of the sample pretreatment was adjusted to 95°C and incubated for 10 minutes, so that the comparative Difficult-to-break Gram-positive ba...

Abstract

An establishment method of a gene library of fecal flora based on high-throughput gene sequencing employs a ''nested PCR'' method for enrichment amplification on 16S rDNA, so as to reduce the host and food residue genome pollution by the maximum; and V3 and V6 are combined for specific amplification and massive parallel sequencing, so as to obtain the a target gene sequence database of the flora. The library can increase the identification of the bacterial flora from Genus level to Species level. The method can maximally avoid the interference of host cell nucleic acid, and completely and efficiently detect 16SrDNA tag sequence of all bacteria varieties, so as to accurately determine the ecological structure of the intestinal flora.

Description

technical field [0001] The invention belongs to the technical field of molecular biology detection methods for bacteria in the field of biotechnology, and in particular relates to a method for establishing a fecal flora gene library based on high-throughput gene sequencing. Background technique [0002] In recent years, the relationship between gut microbes, diet and health has been increasingly explained, largely due to the rapid development of gut microbiome research technology. The research on gut microbes has generally gone through three stages: culture-dependent methods, culture-independent traditional molecular biology methods, and sequencing-based high-throughput omics methods. [0003] By comparing the characteristics and applications of the research methods in the three stages, people can find that the culture-dependent method can obtain the corresponding strains while identifying the strains, which is convenient for subsequent research, but the culture method itsel...
