Successive Intramuscular Boosting with IFN-Alpha Protects Mycobacterium bovis BCG-Vaccinated Mice against M. lepraemurium Infection

Figure 2

Histopathological appearance of the lesions (representative results) in the skin of BCG-primed/IFN-alpha boosted and infected mice with M. lepraemurium ((a) right panel), or BCG-vaccinated/PBS-boosted and infected mice with M. lepraemurium ((a) left panel). Sections were stained with Ziehl-Neelsen and Harris’-Hematoxylin (blue) (×40) (a). Graphics of the skin lesion size in MLML infected mice (b). A difference of was considered statistically significant.
