Figure 7From: Evolution of foot-and-mouth disease virus intra-sample sequence diversity during serial transmission in bovine hostsShannon entropy (left panel) and dn/ds (right panel), across all samples. Validated mutations at frequencies above 0.5% were included in these analyses. The complexity of viral populations fluctuates across samples, with lower values often found in correspondence of foot lesions. dn/ds ratios show a clear decreasing trend along the transmission chain.Back to article page
