Microbiome analysis of control, radiation enteritis model, and treatment groups in rat stool samples using 16S rRNA sequencing

This study investigates the gut microbiome composition and diversity in three groups of rats: control, radiation enteritis model, and treatment (TG) groups. Total DNA was extracted from stool samples, PCR-amplified targeting 16S rRNA gene variable regions, and sequenced using Illumina MiSeq or NovaSeq platforms. Downstream bioinformatics analyses included sequence quality control, denoising (DADA2/OTU clustering), taxonomic classification, alpha and beta diversity evaluation, differential species abundance analysis, and functional prediction. The processed data include ASV/OTU tables, taxonomy assignments, and sample metadata.
