^aData are derived from day 2 nasal washes of guinea pigs 11 to 15 shown in Fig. 2 (1:1 group) and the guinea pigs shown in Fig. 3. A Student t test was used to compare guinea pigs inoculated with 1:1 and 1:7 mixtures at the 2 × 10⁶ PFU dose. The P values are indicated in the respective column headings.

^bThe number of var parental isolates, divided by the sum of wt + var parental isolates, is shown.

^cThe number of var gene segments included in reassortant genomes, divided by the sum of wt + var gene segments in reassortant genomes, is shown.
