title: mouse-3-Vehicle-baseline
design: Bacterial DNA was extracted from stool using a MoBio fecal DNA extraction kit (Mo Bio Laboratories, Carlsbad, CA, USA) after bead beating and prepared for sequencing using the Nextera XT Library Prep Kit (Illumina, Inc., San Diego, CA, USA ).  All samples were sequenced together in paired-end mode on an Illumina MiSeq instrument.
