Figure 6From: Evolution of foot-and-mouth disease virus intra-sample sequence diversity during serial transmission in bovine hostsMutation spectra of samples collected from the cattle. Plots (for each animal) represent the abundance of mutations at frequencies above 0.5% across the different samples: in some cases (typically probangs and sera) the mutation spectrum smoothly decreases in abundance as the frequency of mutations increases. However, in some samples (typically feet), the intermediate frequency region is depleted, suggesting narrow bottlenecks.Back to article page
