Recovery and mass yield from mock skin and swab samples with phage T4. Bacterial (a) and phage T4 (b) DNA recoveries were determined by qPCR for a single sample load (1.0 × 108 virions and 1.0 × 107 cells). Negative controls for qPCR containing no template were not quantifiable after 40 cycles of PCR. DNA composition (c) and phage:cell ratios (d) as determined by qPCR characterize T4 enrichment in the VLP fraction. Error bars indicate standard deviation among biological triplicates
