A New Experimental Infection Model in Ferrets Based on Aerosolised Mycobacterium bovis

Figure 1

The mean postmortem scores for each group of ferrets infected with either 0.8×10² or 1.1×10³ CFU M. bovis and examined postmortem at either 8 or 20 weeks post infection. Differences between the 10² and 10³ CFU infection groups at 8 weeks post infection were significant at the 𝑃<.001 level, while differences at week 20 post infection were significant at the 𝑃<.01 level.
