Project description:We report the use of high-throughput sequencing technology to detect the microbial composition and abundance of human feces after in vitro co-fermentation with citrus peel flavonoid extracts. The genomic DNA was obtained by the QIAamp PowerFecal DNA Kit. Then, the DNA samples were sent to Biomarker Bio-Tech (Beijing, China) for V3-V4 region of the 16S rDNA gene high-throughput sequencing with an Illumina MiSeq platform. DNA samples were sequenced using primers 338F (forward primer sequence ACTCCTACGGGAGGCAGCAG)-806R (reverse primer sequence GGACTACHVGGGTWTCTAAT). A total of 8,816,250 pairs of Reads were obtained from the 112 samples sequenced, and 8,721,112 Clean Reads were generated from the double-ended Reads after quality control and splicing. The sequencing analyses were carried out using the SILVA database as a reference for the assignation of operational taxonomic units (OTUs) with 97% of identity.
Project description:We used 16S V3/V4 region amplification to evaluate the composition of bacteria species in mouse fecal pellets after vehicle or ABX treatment and before and after fecal matter transplant.
Project description:We examined 36 biopsies taken from digital dermatitis lesions of Holstein cows. The target was the V3 -V4 variable region of 16S rRNA using Treponema specific primers. We identified 20 different taxa of Treponema using this approach.
