FIG. 1.
Anti-IL-5 MAb treatment of IFN-γR−/− mice eliminates BCG infection-induced blood eosinophilia. IFN-γR−/− age- and sex-matched mice were infected intranasally with 5 × 105 BCG strain Pasteur organisms and were treated with anti-IL-5 MAb or with control rat IgG. Blood samples were taken at the time points indicated after BCG infection. Differential counts were made by staining blood smears with Diff-Quik. Data points represent the mean number (± standard error) of eosinophils per milliliter of blood from five mice.
