The number of rears during 20 min in the open field was recorded in the immunized group (a) and non-immune control (b) mice. The differences of rears (F(1,10) = 4.514, p = .0596) and unsupported rears (F(1,10) = 4.233, p = .0667) between C57BL/6J non-immune control and immunized groups approached, but did not achieve, statistical significance. Statistically significant differences were not observed in the other genetic strains of mice.
