Lesion progression in control BALB/c mice after challenge with 10⁶ L. major metacyclic enriched promastigotes. Each experiment is repeated three times. Results of the 3 experiments (10 mice per group) pooled together are expressed as increases in footpad thickness (in millimetres) and are means + S.D. PBS-F2 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F2); PBS-F3 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F3); PBS-F4 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F4); PBS-F5 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F5); PBS-F6 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F6); PBS-F14 (control group): mice pre-immunized with PBS only and challenged with L. major co-inoculated with SGH of female P. papatasi (F14);
