Metagenomic Profile of Fecal Samples Generated From Mouse Model Simulating Features of Post-Traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is an anxiety disorder that can arise due to exposure to a potentially traumatic event (PTE). Using "cage-within-cage resident-intruder" protocol, subject C57BL/6J mice were exposed to aggressor mice for 10 days with 24 hours rest prior to harvesting. The symbiotic influence of microbiota on the nervous system and behavior has been receiving profound interest. In this longitudinal study, we are focusing on the effect of social stress on the microbiome by sequencing for 16S ribosomal RNA (16S rRNA) amplicon on the Illumina MiSeq platform. Fecal samples were collected at 2 day intervals during the 10 day protocol from control as well as subject mice. DNA was isolated using a kit from MO BIO followed by amplification of variable V3 and V4 region of the 16S rRNA amplicon using the Illumina 16S Metagenomics Library Preparation Protocol. The samples were barcoded using Nextera index primers and pooled in preparation for MiSeq sequencing. We will be able to characterize the ...
