CFU counts at extrapulmonary locations at necropsy. Single-animal CFU counts for the spleen (S), liver (L), kidney (K), abdominal lymph node (AN), adrenal gland (Ad), ovary (Ov), bone marrow (BM), feces (F), colon (Cn), cecum (Cm), and appendix (Ap) are shown. Results for rabbits infected with M. bovis Ravenel (R) and AF2122 (AF) are shown because these strains were most likely to result in extrapulmonary dissemination.
