FIG. 1.

(A and D) Disease patterns in BALB/c (triangles), C3H/HeN (circles), and C57BL/6J (squares) mice infected intradermally in the ear (A) or tail (D) with 10⁴ L. major Friedlin metacyclic promastigotes. The means and standard deviations of the lesion scores are shown as a function of time. (B and E) Parasite burden per 10⁶ lymph node cells in individual mice tested at 5, 10, and 15 weeks after infection with 10⁴ L. major Friedlin metacyclic promastigotes in the ear (B) or tail (E). (C and F) Ratios of IFN-γ to IL-4 in individual mice tested at 0, 5, 10, and 15 weeks post infection with 10⁴ L. major Friedlin metacyclic promastigotes in the ear (C) or tail (F).
