Determination of CD45+ mononuclear cells infiltrating tumors derived from λ3 phage vaccinated mice. Numerous CD45+ mononuclear cells had infiltrated tumors derived from λ3 phage vaccinated animals (right panel) as compared to the control (left panel). There was a significant difference in the quantity of CD45+ cells between the two representative tumors (**p < 0.01). The bar graphs depicted the quantitative data obtained from multiple sections derived from three control and three λ3 phage vaccinated mice with respect to CD45+ cell infiltration into the tumor parenchyma. The total number of CD45+ cells were determined at 1000× from 10 high powered fields in each tumor section.
