The 16S sequencing of cecal contents from Kunming mice
16S sequencing of cecal contents from Kunming mice is a core technology for analyzing their intestinal microbial communities. This technology involves extracting bacterial genomic DNA from cecal content samples, designing primers for the variable regions of the 16S rRNA gene to perform PCR amplification, enriching bacterial taxonomic characteristic fragments, and then using high-throughput sequencing to obtain massive sequence data. Through bioinformatics analysis, the sequencing data can be compared with known bacterial databases to identify the species, relative abundances, and community diversity of bacteria in the cecal contents. This process requires strict adherence to aseptic sampling procedures to ensure that samples are not contaminated by external sources, and quality control steps are implemented to guarantee the quality of DNA extraction and amplification. Using this technology, researchers can systematically analyze the dynamic changes in the cecal microbiota of Kunming mice under scenarios such as disease models, drug interventions, or dietary adjustments, revealing the association between microbiota composition and host health. This provides critical data support for research on intestinal microecological mechanisms, disease diagnosis, and the development of targeted intervention strategies.
