Summary of the main virulence and lethality characteristics of the studied strains. Observations are mostly for the period between days 14 and 56 p.i. The cumulative average index was based on lethality, lung weight coefficient, and lung damage of survived mice at 196 dpi within the survival series. In addition, the high, intermediate, and low values are marked by color (red, orange, and blue, respectively).
