Data for the number of CFU present in the tracheobronchial lymph nodes (TBLN) and blood of rabbits at different times after exposure to a mean inhaled dose of 4.428 × 107 spores.

The number of CFU in the TBLN could not be quantified for all rabbits at 24h and 36h, due to the CFU being too numerous to count after plating. This is why we only have a lower bound for the number of CFU for some of the rabbits at these times. For the rabbits that died before the time point at which they were scheduled to be sacrificed, we assume that if they had survived then their CFU measurement would have been greater than the highest measurement observed for a surviving animal, which was CFU in the TBLN and CFU in the blood. These data were obtained during the study published by Gutting et al. [22]
