摘要：We compared commercial kits for extraction of genomic DNA from the Gram-negative bacterium Klebsiella pneumoniae for subsequent Miseq sequencing. Purification of DNA was based on matrix binding (silica or anion exchange resin) or differential precipitation (salting out), respectively. The choice of extraction kit had little effect on sequencing quality and coverage across drastically different replicons, except for an apparent depletion of small plasmids (<5 kb) during precipitation-based extractions. Sequencing coverage provided copy-number estimates for small plasmids that were consistently higher than those from quantitative real-time PCR.
