      <DESIGN_DESCRIPTION>Stool total bacterial DNA extraction was performed using the Spin stool DNA kit (Stratec Molecular, Berlin, Germany), according to the manufacturer's instructions. 16S rRNA gene amplicon libraries were performed with a two-step barcoding approach according to Illumina 16S Metagenomic Sequencing Library Preparation (Illumina, San Diego, CA, USA). Library concentration and exact product size were measured using a KAPA Library Quantification Kit (Kapa Biosystems,Woburn, MA, USA) and an Agilent 2100 Bioanalyzer System (Agilent, Santa Clara, CA, USA), respectively. A pooled library (20 nM) and a PhiX control v3 (20 nM) (Illumina) were mixed with 0.2 N fresh NaOH and hybridization buffer HT1 (Illumina) to produce the final concentration at 12 pM each. The resulting library was mixed with the PhiX control v3 (5%, v/v) (Illumina) and 600  L loaded on a MiSeq  v2 (500 cycle) Reagent cartridge for obtaining a paired-end 2   272 bp sequencing.</DESIGN_DESCRIPTION>

      <DESIGN_DESCRIPTION>Stool total bacterial DNA extraction was performed using the Spin stool DNA kit (Stratec Molecular, Berlin, Germany), according to the manufacturer's instructions. 16S rRNA gene amplicon libraries were performed with a two-step barcoding approach according to Illumina 16S Metagenomic Sequencing Library Preparation (Illumina, San Diego, CA, USA). Library concentration and exact product size were measured using a KAPA Library Quantification Kit (Kapa Biosystems,Woburn, MA, USA) and an Agilent 2100 Bioanalyzer System (Agilent, Santa Clara, CA, USA), respectively. A pooled library (20 nM) and a PhiX control v3 (20 nM) (Illumina) were mixed with 0.2 N fresh NaOH and hybridization buffer HT1 (Illumina) to produce the final concentration at 12 pM each. The resulting library was mixed with the PhiX control v3 (5%, v/v) (Illumina) and 600  L loaded on a MiSeq  v2 (500 cycle) Reagent cartridge for obtaining a paired-end 2   279 bp sequencing.</DESIGN_DESCRIPTION>

The resulting library was mixed with the PhiX control v3 (5%, v/v) (Illumina) and 600  L loaded on a MiSeq  v2 (500 cycle) Reagent cartridge for obtaining a paired-end 2   261 bp sequencing.</DESIGN_DESCRIPTION>

      <DESIGN_DESCRIPTION>Stool total bacterial DNA extraction was performed using the Spin stool DNA kit (Stratec Molecular, Berlin, Germany), according to the manufacturer's instructions. 16S rRNA gene amplicon libraries were performed with a two-step barcoding approach according to Illumina 16S Metagenomic Sequencing Library Preparation (Illumina, San Diego, CA, USA). Library concentration and exact product size were measured using a KAPA Library Quantification Kit (Kapa Biosystems,Woburn, MA, USA) and an Agilent 2100 Bioanalyzer System (Agilent, Santa Clara, CA, USA), respectively. A pooled library (20 nM) and a PhiX control v3 (20 nM) (Illumina) were mixed with 0.2 N fresh NaOH and hybridization buffer HT1 (Illumina) to produce the final concentration at 12 pM each. The resulting library was mixed with the PhiX control v3 (5%, v/v) (Illumina) and 600  L loaded on a MiSeq  v2 (500 cycle) Reagent cartridge for obtaining a paired-end 2   258 bp sequencing.</DESIGN_DESCRIPTION>
