Data for the number of CFU and amount of PA present in the blood of guinea pigs at different times after exposure to a mean dose of 2 × 107 spores.

For the guinea pigs that died before the time point at which they were scheduled to be sacrificed, we assume that if they had survived then their CFU and PA measurements would have been greater than the highest measurements observed for a surviving animal, which were 2.5 × 1010 CFU and 1.5 × 106 ng of PA. These data have been obtained from [23, Fig 3] and converted to the amounts in the whole blood compartment by assuming a volume of 57 ml of blood in a guinea pig.
