Cutaneous leishmaniasis is typically characterized by localized skin lesions, but the extent to which Leishmania amazonensis disseminates beyond the primary site of infection remains incompletely defined. In this study, BALB/c mouse footpads were infected subcutaneously with L. amazonensis promastigotes at doses ranging from 105 to 108, and infection was evaluated over time up to 120 days. All infected groups developed local footpad infection, and amastigotes were detectable at the infection site early after challenge. Footpad swelling and parasite burden increased progressively, with more pronounced local lesion development observed at higher infective doses. At an infective dose of 1 × 106, viable parasites were recovered predominantly from the footpad and bone marrow, with only limited detection in the spleen at later time points. In contrast, infection with 1 × 108 promastigotes resulted in broader dissemination, with viable parasites detected in the bone marrow and spleen and, at later stages of infection, in the liver and peripheral blood. Parasite-specific IgG, IgG1, and IgG2a antibody responses were also higher in the 1 × 108 infection group than in the 1 × 106 group. These findings show that experimental L. amazonensis infection is not uniformly restricted to the skin and that viable parasite dissemination to non-cutaneous tissues is influenced by inoculum size and infection duration.
