Ecological Niche Modelling Predicts Southward Expansion of Lutzomyia (Nyssomyia) flaviscutellata (Diptera: Psychodidae: Phlebotominae), Vector of Leishmania (Leishmania) amazonensis in South America, under Climate Change

Vector borne diseases are susceptible to climate change because distributions and densities of many vectors are climate driven. The Amazon region is endemic for cutaneous leishmaniasis and is predicted to be severely impacted by climate change. Recent records suggest that the distributions of Lutzomyia (Nyssomyia) flaviscutellata and the parasite it transmits, Leishmania (Leishmania) amazonensis, are expanding southward, possibly due to climate change, and sometimes associated with new human infection cases. We define the vector’s climatic niche and explore future projections under climate change scenarios. Vector occurrence records were compiled from the literature, museum collections and Brazilian Health Departments. Six bioclimatic variables were used as predictors in six ecological niche model algorithms (BIOCLIM, DOMAIN, MaxEnt, GARP, logistic regression and Random Forest). Projections for 2050 used 17 general circulation models in two greenhouse gas representative concentration pathways: “stabilization” and “high increase”. Ensemble models and consensus maps were produced by overlapping binary predictions. Final model outputs showed good performance and significance. The use of species absence data substantially improved model performance. Currently, L. flaviscutellata is widely distributed in the Amazon region, with records in the Atlantic Forest and savannah regions of Central Brazil. Future projections indicate expansion of the climatically suitable area for the vector in both scenarios, towards higher latitudes and elevations. L. flaviscutellata is likely to find increasingly suitable conditions for its expansion into areas where human population size and density are much larger than they are in its current locations. If environmental conditions change as predicted, the range of the vector is likely to expand to southeastern and central-southern Brazil, eastern Paraguay and further into the Amazonian areas of Bolivia, Peru, Ecuador, Colombia and Venezuela. These areas will only become endemic for L. amazonensis, however, if they have competent reservoir hosts and transmission dynamics matching those in the Amazon region.

“…Other studies have identified the presence of phlebotomines responsible for the leishmaniasis transmission on the banks of Araguari river basin (LEMOS;LIMA, 2005;PAULA et al, 2013), in the urban area of Uberlândia (PAULA et al, 2008) and in the Sabiá Park, in Uberlândia. (RODRIGUES et al, 2011). Since 1992 there is no record of human leishmaniasis cases occurred in Triângulo Mineiro region and it is essential to know the epidemiological profile of the disease, as it makes possible to identify needs and propose solutions to problems, leading to health actions.…”

ABSTRACT:The purpose of this study was to describe clinic-epidemiological characteristics of leishmaniasis cases attended at the Clinical Hospital of Federal University of Uberlândia (CHU), state of Minas Gerais, from January 2000 to December 2013. This is a descriptive and retrospective review of medical records of patients diagnosed with leishmaniasis and treated at the CHU. 168 cases of leishmaniasis were analyzed and most patients were male, aged 23 to 60 years. For cutaneous and mucosal leishmaniasis, single lesions, located mainly in lower limbs and head (CL) and nasal mucosa (ML), were the most common clinical presentation. Regarding the diagnosis, the most performed methods for CL and ML were biopsy plus histopathology and biopsy plus immunohistochemistry; biopsy plus direct parasitological examination methods were the most frequent for VL. Most patients (84%) received treatment, mainly glucantime for both CL and ML; VL treatment was based on amphotericin B or glucantime. According to data from Sistema de Informações de Agravos de Notificação (SINAN), the Brazilian information system to notify and investigate cases of diseases and their aggravations, no case has been confirmed as autochthonous. It is noteworthy the underreporting of cases and the lack of complete information in medical records. Our results may contribute to a better understanding of the real situation in Uberlândia region concerning to leishmaniasis.

SUMMARYWe analyzed the sandflies around houses and domestic animal shelters located in residences close to forests in localities on the banks of the Araguari River, Uberlândia, MG, from February 2003 to November 2004. The phlebotomines were captured in the peridomiciliary area, where Shannon traps were utilized in the peridomicile and CDC traps in animal shelters. 2,783 specimens of sandflies were captured, 2,140 females (76.9%) and 643 males (23.1%), distributed between 17 species. The most abundant species was Nyssomyia neivai (88.1%), followed by Nyssomyia whitmani (3.1%). The presence of Lutzomyia longipalpis was also confirmed, it is the main vector of Leishmania (L.) infantum chagasi which causes visceral leishmaniasis. The presence of species involved in the transmission of leishmaniases in the municipality of Uberlândia is cause for concern. The presence of L. longipalpis indicates that its urbanization may not have been aleatory and instead occurred through the destruction of wild ecotopes. More studies of their occupation in anthropic environments need to be made.
