The goal of the present study was to evaluate the spatial distribution of American cutaneous leishmaniasis (ACL) in Seropédica, Rio de Janeiro State, Brazil according to the favorability of occurrence. The Vista-SAGA Geo-environmental Analysis System (Sistema de Análise Geoambiental Vista-SAGA) was used to create a database (theme maps) and perform environmental analyses, signatures and combinations. The degrees of likelihood were obtained by evaluating soil use and plant cover; soil type and geomorphology (geo-environmental factors); and altitude and slope (topographic factors). The factors used in the analyses were selected based on results from the literature and according to the technical feasibility of their inclusion in the databases. Weights and grades were attributed to the factors and their categories, respectively, according to their relevance to the life cycle of parasites from genus Leishmania and parasite vectors. Based on the results of the environmental analyses, areas were classified and grouped to represent the spatial distribution of favorability. Areas were classified as very unfavorable, unfavorable, somewhat favorable, favorable and very favorable for ACL occurrence. The results of the signature analyses showed that the municipality included 6.81% very favorable areas, 65.14% favorable areas, 17.98% somewhat favorable areas, 2.39% unfavorable areas and 0.07% very unfavorable areas for ACL occurrence. The signature analyses of the results and theme maps were able to locate and characterize the ecosystem profiles in terms of risk of ACL occurrence, indicating that rural, peri-urban and urban areas of the municipality of Seropédica may be classified as favorable for the occurrence of this disease. The results of the present study may be used to support management decisions made by authorities responsible for ACL control and prevention in Seropédica. In addition, geoprocessing was found to be a low-cost alternative for data integration in areas where it is difficult to perform surveys. Análise Geoambiental Vista-SAGA foi utilizado na preparação das bases de dados (mapas temáticos), análise ambiental, assinaturas e combinação. Os graus de favorabilidade foram obtidos por avaliações procedidas sobre os fatores uso do solo e cobertura vegetal, tipo de solo e geomorfologia (fatores geoambientais) e altitude e declividade (fatores topográficos). Os fatores utilizados nas análises foram selecionados com base na literatura e na viabilidade técnica para a preparação das bases de dados. Pesos e notas foram atribuídos aos fatores e suas categorias, respectivamente, conforme a relevância para o ciclo de vida de parasitos do gênero Leishmania e de seus vetores. Os resultados das análises ambientais foram categorizados para representarem a distribuição espacial da favorabilidade, classificada como áreas pouquíssimo favorável, pouco favorável, favorável, muito favorável e muitíssimo favorável para ocorrência de LTA. Os resultados das assinaturas evidenciam que o município apresenta 6,81% da área class...

“…Among the three municipalities where the animals lived, the highest seropositivity was found in Seropedica, followed by Itaguai and Mangaratiba. In a study performed by Cardoso et al (2009) in Seropedica, species of sandflies vectors of cutaneous leishmaniasis were captured, suggesting that these species are potential vectors of leishmaniasis in the municipality and that dogs should be considered potential reservoirs of this parasite due to the high frequency of seropositivity detected. Souza et al (2009) and Aguiar et al (1996), analyzing sandflies in the green coast of the State of Rio de Janeiro, found some species of great epidemiological importance.…”

This study evaluated factors associated with the frequency of Leishmania spp. antibodies in dogs residing in the Itaguai micro-region, State of Rio de Janeiro, Brazil. Blood samples were collected from 524 dogs. The serum samples were submitted to indirect fluorescent antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA) for Leishmania spp. The frequency of seropositive dogs was 28.24% (n = 148) in the micro-region, and among the three municipalities within that region, the highest frequency (p < 0.05) was observed in Seropedica (59.46%), followed by Itaguai (29.05%) and Mangaratiba (11.49%). Regarding factors associated with the host, mongrel dogs and those over the age of two presented higher frequency of antibodies to Leishmania spp. (p < 0.05). Concerning factors related to the environment and habits of the animal, dogs residing in rural areas (FR = 1.67, p = 0.0002), living outside the residence (FR = 1.42, p = 0.0197), with access to forest, streams and pastures (FR = 2.81, p = 0.0007), remaining loose (FR = 1.66, p = 0.0073), and those that had no shelter (FR = 2.16, p < 0.0001) were more likely to be seropositive. Canine leishmaniasis is a disease with high occurrence in the Itaguai micro-region, and aspects such as the definition of breed, age, habits and care by owners showed significant association in this micro-region.

“…(N.) whitmani, which is incriminated as one of the vectors of Leishmania (Viannia) braziliensis, the most prevalent parasite infecting humans and one of the main species involved in American cutaneous leishmaniasis (ACL) in Brazil, is also associated with the presence of domestic animals 6,11,13 . Studies carried out in areas of ACL transmission in Minas Gerais have found L. (N.) whitmani displaying great behavioral flexibility, anthropophilic activity in surrounding woods and around human dwellings, where it may be developing hematophagous habits involving humans and domestic animals 14,17 .…”

SUMMARYBetween April 2003 and May 2009 phlebotomine sandflies were collected in Parque do Sabiá complex, Uberlândia municipality, Minas Gerais State, Brazil, using CDC and Shannon traps. The objective was to associate the sandfly species captured to the risk of the transmission of leishmaniasis in the municipality. The 126 captured specimens belonging to six species of phlebotomine, among which Lutzomyia (Psychodopygus) davisi (Root, 1934) predominated with 113 specimens (89.7%). The remaining captured species were Lutzomyia (Pintomyia) mamedei Oliveira, Afonso, Dias & Brazil, 1994 -five specimens (3.9%); Lutzomyia (Nyssomyia) flaviscutellata (Mangabeira, 1942) -four specimens (3.2%); Lutzomyia lenti (Mangabeira, 1938) -two specimens (1.6%); Brumptomyia avellari (Costa Lima, 1932) -one specimen (0.8%); and Lutzomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1939) -one specimen (0.8%). The collection of species that may be involved in the transmission of Leishmania reveals the need for continuous entomological surveillance.
