Evolutionary interactions between haemagglutinin and neuraminidase in avian influenza

Table 6 Average d _N / d _S across H7 avian influenza HA1 for lineages corresponding to different avian host orders

Avian host order	Mean d_N/d_S	Lower 90% HPD limit for d_N/d_S	Upper 90% HPD limit for d_N/d_S
Anseriformes	0.113	0.065	0.158
Galliformes	0.135	0.091	0.177
Other	0.100	0.057	0.141

Stochastic mutational mapping was used to calculate d_N/d_S along lineages corresponding to viruses from different avian host orders (Anseriformes, Galliformes and others) for 1000 MCMC tree samples, in an analogous manner to that described for comparisons by background NA subtype.
