Effects of streptococcal exposure on (a) food manipulation, (b) beam walking, (c)
grooming, and (d) activity. (a) Food manipulation was impaired in GAS-exposed rats. The
mean and SE of food manipulation score of GAS rats (n=19) and control
rats (n=16). (b) Beam walking was impaired in GAS-exposed rats on the
narrow beam only. The mean and SE of the time spent on the wide and narrow beams of GAS
rats (n=9) and control rats (n=10). (c) Induced-grooming
was enhanced by GAS exposure. The mean and SE of the duration of induced-grooming on
three sessions of GAS (n=8) and control (n=8) rats. (d)
Activity tended to increase following GAS exposure. The mean and SE of activity counts,
in 5 min blocks, of GAS (n=20) and control (n=17)
rats during a 30-min activity session. *Significantly different from the
control group, P<0.05.
