Data of "A workflow to study the microbiota profile of piglet's umbilical cord blood: from sampling to data analysis".

The present study proposes a workflow – from the sampling method to DNA extraction, bioinformatics and data analysis – that characterises the bacterial profile of umbilical cord blood samples, taking into account the contaminants found throughout the procedure of bacterial DNA extraction and amplification. Ps_umbilical.rds: A phyloseq object file of data containing the amplicon sequences variants (ASVs) of thirteen umbilical cord samples and two negative control samples, created by DADA2. R-script.doc: A word document containing the scripts used to characterize the taxonomical composition of the fifteen umbilical cord samples and two negative control samples before and after the application of Decontam R-package (Davis et al., 2018). data_description.xlsx: meta data for R-script.doc
