Figure 6. Bacillary load in the lungs of rats following immunosuppression.
Rats were infected with 102 CFU of M. tuberculosis strain W4 and either left untreated or treated with dexamethasone for one month starting at 100 days post- infection. Lung bacillary load was quantified at 130 days post-infection (* Pā=ā0.025 and 0.036 for exp 1 and 2, respectively).
