Table 2. Pregnancy events and fetal outcomes after oral infection.
Distribution of pregnancies, number of fetuses and resorptions were significantly different among groups (P<0.01, Chi square). Fetuses from infected mice were smaller and lighter on average, but fetal lengths were not different among all groups (P=0.08, ANOVA). CMC=carboxymethylcellulose; CFU=colony forming units.
