BACKGROUND Leishmania (Viannia) parasites present particular challenges, as human and murine immune responses to infection are distinct from other Leishmania species, indicating a unique interaction with the host. Further, vaccination studies utilizing small animal models indicate that modalities and antigens that prevent infection by other Leishmania(More)
BACKGROUND Previous findings indicate that susceptibility to Leishmania (Viannia) panamensis infection of monocyte-derived macrophages from patients and asymptomatically infected individuals were associated with the adaptive immune response and clinical outcome. METHODOLOGY/PRINCIPAL FINDINGS To understand the basis for this difference we examined(More)
The genomic organisation of the gene encoding Leishmania (Leishmania) amazonensis arginase as well as its flanking regions were characterised. The size of the transcribed RNA was determined, allowing us to map the genomic sites signalling for RNA trans-splicing and putative polyadenylation regions. The general organisation was compared with genes encoding(More)
