Abstract
A remarkable characteristic of infectious diseases classified as Neglected Tropical Diseases (NTDs) is the fact that they are mostly transmitted in tropical and subtropical regions with poor conditions of sanitation and low access to healthcare, which makes transmission areas more likely to overlap. Two of the most important NTDs, schistosomiasis and leishmaniasis, despite being caused by very different etiological agents, have their pathogenesis heavily associated with immune-mediated mechanisms, and Schistosoma spp. and Leishmania spp. have been shown to simultaneously infect humans. Still, the consequences of Schistosoma-Leishmania coinfections remain underexplored. As the inflammatory processes elicited by each one of these parasites can influence the other, several changes have been observed due to this coinfection in naturally infected humans, experimental models, and in vitro cell assays, including modifications in susceptibility to infection, pathogenesis, prognostic, and response to treatment. Herein, we review the current knowledge in Schistosoma-Leishmania coinfections in both human populations and experimental models, with special regard to how schistosomiasis affects tegumentary leishmaniasis, discuss future perspectives, and suggest a few steps to further improve our understanding in this model of parasite-host-parasite interaction.

Abstract
In the context of infectious diseases, non-human primates (NHP) provide the best animal models of human diseases due to the close phylogenetic relationship and the similar physiology and anatomical systems. Herein, we summarized the contribution of NHP models for understanding the immunity to leishmaniases, which are a group of diseases caused by infection with protozoan parasites of the genus Leishmania and classified as one of the neglected tropical diseases.

Abstract
Parasitic diseases affect more than one billion people worldwide, and most of them are chronic conditions in which the treatment and prevention are difficult. The appearance of granulomas, defined as organized and compact structures of macrophages and other immune cells, during various parasitic diseases is frequent, since these structures will only form when individual immune cells do not control the invading agent. Th2-typering various parasitic diseases are frequent, since these structures will only form when individual immune cells do not control the invading agent. The characterization of granulomas in different parasitic diseases, as well as recent findings in this field, is discussed in this review, in order to understand the significance of the granuloma and its modulation in the host-parasite interaction and in the immune, pathological, and parasitological aspects of this interaction. The parasitic granulomatous diseases granulomatous amebic encephalitis, toxoplasmosis, leishmaniasis, neurocysticercosis, and schistosomiasis mansoni are discussed as well as the mechanistic and dynamical aspects of the infectious granulomas.

Abstract
We have recently introduced a macaque (Macaca mulatta) model of Leishmania braziliensis-induced chronic granulomatous cutaneous lesions affecting the nasal mucosa. Using an L. braziliensis strain that produces self-healing dermal lesions in macaques, here we characterises the systemic and local cell-mediated immune responses that led to controlled growth of granulomas in the infected host. As detected using flow cytometry, more cytokine-producing T-cell subsets were observed in granuloma-derived leukocytes that were analysed directly ex vivo than in the in vitro-restimulated cells from the peripheral blood and skin-draining lymph nodes (dLNs). We demonstrate that antigen-specific interferon-gamma (IFN-gamma)- or tumour necrosis factor alpha (TNF-alpha)-producing CD4(+) and CD8(+) cells are likely important for the immunological effectiveness of granulomas. However, their resolution can be ascribed to the concomitant recruitment of interleukin (IL)-10-producing CD4(+)CD25(+) regulatory T (Treg) cells that suppress the effector T-cell-mediated inflammatory response. The findings confirm that the macaque model can be used to fully elucidate the regulatory mechanisms that may render granulomas inadequate for fighting intracellular pathogens, which will need to be considered in the development of any therapeutic strategy designed to prevent immune pathology.

Abstract
The aim of this study was to evaluate the histopathological features in tissues of mice infected by human isolates (I, II, and III) or the reference M2903 strain of Leishmania braziliensis complex. BALB/c and C57Bl/6 mice were infected in the hind footpad with 10(6) stationary-phase promastigotes of L. braziliensis complex. The evolution of lesions was observed for 10 weeks and the animals were then euthanized and liver, spleen and popliteal lymph nodes were collected. Tissues were stained with hematoxylin and eosin and analyzed by immunohistochemistry assay. Increased thickness of infected footpads was observed in all animals, lesions were nodular and non-ulcerated. Mice infected with isolate I presented inflammatory infiltrates consisting predominantly of mononuclear cells in all tissues examined, and also a great number of megakaryocytes, compared with other isolates. Infection with isolate II led to an infected footpad enlargement not seen in other isolates. In addition, mononuclear infiltrates in the liver and hemosiderin in spleen were noted. Conversely, mice infected with either isolate III or M2903 strain only showed an increased number of megakaryocytes in spleen. All tissues examined had detectable amastigote forms of Leishmania by immunohistochemistry in all groups. Taking together, our results showed an unforeseen behavior of different isolates of L. braziliensis complex that led to diverse pathological findings.

Abstract
Leishmaniasis causes significant morbidity and mortality, constituting an important global health problem for which there are few effective drugs. Given the urgent need to identify a safe and effective Leishmania vaccine to help prevent the two million new cases of human leishmaniasis worldwide each year, all reasonable efforts to achieve this goal should be made. This includes the use of animal models that are as close to leishmanial infection in humans as is practical and feasible. Old world monkey species (macaques, baboons, mandrills etc.) have the closest evolutionary relatedness to humans among the approachable animal models. The Asian rhesus macaques (Macaca mulatta) are quite susceptible to leishmanial infection, develop a human-like disease, exhibit antibodies to Leishmania and parasite-specific T-cell mediated immune responses both in vivo and in vitro, and can be protected effectively by vaccination. Results from macaque vaccine studies could also prove useful in guiding the design of human vaccine trials. This review summarizes our current knowledge on this topic and proposes potential approaches that may result in the more effective use of the macaque model to maximize its potential to help the development of an effective vaccine for human leishmaniasis.

Abstract
Visceral leishmaniasis (VL) was experimentally induced in rhesus macaques (Macaca mulatta) by intravenously inoculating 2 x 10(7)amastigotes/kg of body weight of Leishmania infantum. The macaques developed a systemic disease showing characteristic features of human VL such as fever, diarrhoea, body weight loss, anaemia, hypergammaglobulinaemia and transient lymphocytosis, as well as lymph node, liver and/or spleen enlargement. Nine weeks after infection, one primate showed pronounced weight loss, became moribund and was euthanized. The necropsy findings included granulomas composed of parasite-containing macrophages, lymphocytes and plasma cells in the liver, spleen and lymph nodes. The remaining macaques had a sustained course of infection but developed a mild-to-moderate illness that subsequently showed evidence of self-cure. Of note, pathological findings included a typical cell-mediated immunity-induced granulomatous reaction that had an effect on the control of parasite replication. All infected monkeys responded with increased production of anti-Leishmania-specific IgG antibodies. Despite the fact that clinical resistance to L. infantum was not consistently associated with a parasite-specific cell-mediated immune response, drug-cured macaques from the primary infection acquired immunity to homologous re-infection. These findings point to the feasibility of using the L. infantum macaque model for pre-clinical evaluation of novel chemotherapeutics or vaccine candidates for human VL.

Abstract
The antileishmanial efficacy of the reference drug N-methylglucamine antimoniate (Glucantime) was evaluated in groups of rhesus monkeys with acute and chronic Leishmania (Viannia) braziliensis cutaneous infection. The therapeutic responses in experimental animals to either a low dose (5 mg/kg body wt/day for 28 days) or a routine dose (20 mg/kg/day for 28 days) of pentavalent antimony were similar to those reported in the human disease. Primates were cured of their lesions after treatment, but with cryptic parasitism and/or relapse. The rhesus model of L. (V.) braziliensis cutaneous leishmaniasis therefore provides an additional resource for preclinical trials with newer drugs.

Abstract
Ten pairs of Leishmania (Viannia) strains isolated from mucosal and cutaneous lesions of the same patient were analyzed genotypically in order to determine whether populations that had metastasized to mucosal sites differed from those in the cutaneous lesion. The strains were previously characterized by multi locus enzyme electrophoresis and/or monoclonal antibodies reactivity, and, for this study, only isolates from the same patient which were identified as the same species were employed. PCR-RFLP of internal transcribed spacer (ITS) rDNA, random amplified polymorphic DNA (RAPD), and schizodeme analyses were conducted. All genotyping methods revealed microheterogeneity between cutaneous and mucosal isolates from the same patient. The PCR-RFLP of the ITS rDNA and RAPD analysis were numerically analyzed through similarity coefficients and dendrograms were generated. All phenograms clustered cutaneous and mucosal strains of the same patient in one branch with a high degree of similarity, and phenetic analysis matched between them. Schizodeme analysis revealed differences between strains that composed some pairs. Genetic analyses indicate that some populations that metastasize to mucosal sites are distinguishable from the population in cutaneous lesions, however, other approaches will be required to associate genetic polymorphisms with the cutaneous or mucosal phenotype of strains.
