Fig. 4From: Improved single-swab sample preparation for recovering bacterial and phage DNA from human skin and wound microbiomesRecovery 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 triplicatesBack to article page
