Reassortment Patterns in Swine Influenza Viruses
Figure 3
Diversity measurements in swine influenza viruses and the corresponding 95% bootstrap percentile confidence intervals.
Left: Considering the 150 strains in the dataset, NA, HA, and PB1 present a higher diversity than the rest. Right: When the dataset is limited to the classical H1N1 strains isolated in the 70's, 80's, and 90's, which fixes the HA and NA variations in the population, shows a higher diversity in PB1 than the rest of the segments.
