Fragmented Giardia DNA (2 μg, 550 bp insert size) from the trophozoites was first prepared and indexed using Illumina TruSeq DNA PCR-Free Sample Prep Kit (Cat. Nr 20015962 and 20015960S). Library size distribution was validated using the Agilent Technologies 2100 BioAnalyzer, High Sensitivity DNA chip, and quantification was done using the KAPA Library Quantification Kit for Illumina sequencing platforms. Normalized whole genome Giardia DNA-libraries were sequenced using the Illumina MiSeq paired-end technology (2×300 bp). FASTQ-files from the sequencing were assembled and aligned to the corresponding reference genomes of Giardia assemblage A2 and B (v.26) using Bowtie 2-2.2.3.51 (link) The reference genomes were obtained from Giardia DB in January 2016 versions 2013-11-25.52 (link)
