Differential estimates of deposition (in CFU/g) of strain M175 mcr-1 positive E. coli when assessed at different scales. Arrows represent progression from smaller (individuals) to larger scales (flocks and the environment). Estimates represent total accumulations within the flock and environment categories based on the area under the modeled growth curves (see Figs. 2 and 3). Individual estimates are shown for comparison but represent amounts measured every 2–3 days and do not accurately represent total amounts shed by individuals. Images were drawn by Vanessa Sorensen of Sorensen Designs.
