a
Mice were intragastrically infected with 2 × 106 CFU of strain SMrN-9. At each time point, three mice randomly selected from each group were sacrificed by extracting blood. Each group consisted of 24 mice. Data were obtained from two different experiments, and results are expressed as the mean ± standard deviation for six samples.
b
ND, not detectable.
