Fig 3 — Calculated DNA quantity (DNA copies per reaction) in samples collected by FLOQ and Catch-All swabs using the (A) SSR5 and (B) SSR6 assays. Standard curves constructed from assays dilution series were used to determine quantity of genomic DNA, represented as DNA copies per reaction. Each data point represents DNA recovery from one pig ear. The calculated quantity of target DNA recovered using FLOQ swabs was higher than using the Catch-All swabs in both assays. (All DNA copies reported are the mean values of triplicate reaction tested).
