caraya suggests the possible importance of these monkeys in the sylvatic and periurban transmission. in free-ranging howler monkeys gives rise to questions about the actual prevalence of the parasite in the wild, as well as if the number of infected wild monkeys detected may present a risk of leishmaniasis emergence in surronding human populations. amazonensis in the northeastern region of Argentina. Further, we report the first observation of Le. The results also suggest a case of co-infection between Le. Sequence variation of control region mitochondrial DNA, phylogenetic reconstruction, and analysis of molecular variance (AMOVA) were used to determine the degree of genetic structure of Yellow Warblers (Dendroica petechia) in the Galápagos Archipelago. Nine howler monkeys (8.3%) were infected with Le. External ear tissue samples were subjected to PCR amplification for the Leishmania ribosomal internal transcribed spacer (ITS-1) and a RFLP assay with the Hae III restriction enzyme, and finally confirmed by sequencing. in 109 howler monkeys of different ages captured between July and August 2010. caraya serve as potential hosts in the Leishmania cycle, we used molecular methods to examine infection by Leishmania spp. Our study area, in northeastern Argentina, can be considered a southern marginal region for the presence of leishmaniases and includes the habitat of black and gold howler monkeys, Alouatta caraya. Parasitological surveys of non-human primates provides an important opportunity to better understand the epidemiology, transmission dynamics and emergence risk of anthropozoonoses such as leishmaniasis, which affect human populations in several regions accross South America.
