Effects of in vivo depletion of IFN-γ on SGE-3X-inoculated mice. BALB/c mice inoculated i.d. three times (SGE-3X) with Lutzomyia longipalpis SGE were challenged with 105L. braziliensis stationary phase promastigote forms. Animals were treated with normal rat IgG or rat anti-IFN-γ. The course of infection was monitored weekly by measuring the ear lesion size with a metric caliper. In A, the lesion size was determined by the difference between the infected ear and the opposite uninfected ear in millimeters (mm) of at least five mice per group. Data represent the mean ± SEM and are representative of two independent experiments. *P < 0.05 compared with IgG control group. Ear (B) parasite burdens were determined at the 4th week post-infection via a limiting-dilution assay. The data shown are the mean ± SEM of two independent experiments, each performed with five mice per group. #P < 0.05 compared with PBS. *P < 0.05 compared with the SGE-1X group.
