Mechanisms of Immune Evasion, Dissemination, and Persistence in Leishmania amazonensis Infection
Parasite Immunology, Volume 48, Issue 1, January 2026.ABSTRACT Leishmania amazonensis is one of the etiological agents of cutaneous leishmaniasis in its localised form. Moreover, this parasite can cause more severe disease conditions, such as diffuse and disseminated cutaneous leishmaniasis. The development of more severe clinical manifestations is associated with the parasite's ability to establish a ...
