FIG. 1.

B cells are not required for resistance to L. major. Wild-type and μMT mice from the C57BL background were infected with L. major in the hind footpads, and average footpad diameters over time are depicted. Data for infected mice from the genetically susceptible BALB/c background are shown for comparison. Error bars, standard deviations. Results are representative of six experiments, in which a total of 10 wild-type and 15 μMT mice were analyzed.
