The Perils of Pathogen Discovery: Origin of a Novel Parvovirus-Like Hybrid Genome Traced to Nucleic Acid Extraction Spin Columns
Samia N. Naccache et al.
A followup to the discovery of likely the same virus by Baoyan Xu et al. (http://www.pnas.org/content/110/25/10264.full), but the authors of the current paper find the virus not from patient samples, but in silica-based spin columns from Qiagen.
It's a frustrating but important reminder of the extreme importance of controls in highly-sensitive NGS experiments. Even with reagents that have always been reliable in the past.
