^a 1 mL of 10⁸ CFU were inoculated intravenous per kg of body weight and 1 control pig was injected with and equal volume of sterile isotonic saline (mock)
^b PI, after inoculation
^c "-2" indicates that blood was collected 2 min before inoculation
^d Blood was collected 2 min PI
^e Numbers indicate viable counts per ml of blood
^f NT, not tested
^g Result missing
