Whole genome sequencing of Bacteroides fragilis group isolates
gDNA was extracted using the the QIAamp/MoBio BiOstic Bacteremia DNA Kit. 0.5 ng gDNA was used to prepare Illumina sequencing libraries using the Nextera kit (Illumina, San Diego, CA, USA). All libraries were pooled at equal concentrations and sequenced at a target depth of 2 million reads per sample.
