Background: The recent geographic expansion of Leishmania infantum vectors in the triple border area of Argentina, Brazil, and Paraguay has highlighted the need to know the seasonality, parasite infection rate, and the factors that contribute the dispersal and handling of this parasite.
Methods: Entomological, quantitative longitudinal studies were...

Context 1
... abiotic variables selected for this study are shown in Fig. 2, including the mean of the minimum and maximum temperatures and the relative humidity of each night. The maximum (max) and minimum (min) temperatures (T) and the relative humidity (RH) were recorded during the sampling period with digital thermo-hygrometers (TFA, Germany) in each domestic unit. Rainfall and wind velocity data were ...

... a count component that assumes that the predicted abundance values are drawn from a negative binomial distribution [41,42]. The analyses were made separately for three species (Lu. Longipalpis, Nyssomyia whitmani, and Ny. Neivai) and in the intradomicile and peridomicile traps. Since there was a high degree of multicollinearity between variables (Fig. 2), we applied a bidirectional stepwise regression to select which predictors were included in the model [43]. Firstly, we created a correlation matrix between all pairs of environmental factors to test their collinearity. Then, each variable was tested individually with ZINB to predict its inuence on the presence and abundance of ...

Protein-energy malnutrition (PEM) is a risk factor for developing visceral leishmaniasis (VL). While nutrient deficiency can impair immunity, its mechanistic impact on protective adaptive immune responses following Leishmania infection remains unknown. To determine the potential negative impacts of malnutrition on anti-parasitic responses in chroni...
Leishmaniasis is a neglected tropical infectious disease with thousands of cases annually; it is of great concern to global health, particularly the most severe form, visceral leishmaniasis. Visceral leishmaniasis treatments are minimal and have severe adverse effects. As guanidine-bearing compounds have shown antimicrobial activity, we analyzed th...

Background
Immunosuppression is a major risk factor for the development of visceral leishmaniasis (VL). The number of patients receiving immunosuppressant drugs such as TNF antagonist (anti-TNF) and methotrexate (MTX) is increasing. In these patients, VL is more severe, their response to treatment poorer, and they are at higher risk of relapse, a c...
Leishmania infantum is an hemopathogen of importance for the health of domestic dogs (Canis lupus familiaris), causing canine leishmaniasis (CanL), as well as it is the etiological agent of human visceral leishmaniasis (HVL). This parasite was not reported in southern Brazil until the early 2000s, but CanL and HVL were increasingly reported in the...
