Figure 4

Ratio of IFN 𝛾 to IL-4 spots in the mice depicted in Figure 3. Ratios were calculated as the mean number of antigen-specific IFN 𝛾 spots/the mean number of IL-4 spots within each group of mice. Open circles and filled circles represent BCG- and 𝛽 gal-specific IFN 𝛾  : IL-4 ratios, respectively.
