2. The role of gallery forests in maintaining Phlebotominae populations: potential Leishmania spp. vectors in the Brazilian savanna
BACKGROUND Knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence. OBJECTIVE To analyse the occurrence of Phlebotominae in gallery forests and household units (HUs) in the city of Palmas and to determine the rate of natural infection by trypanos

3. PREVALENCE OF AMERICAN TRYPANOSOMIASIS AND LEISHMANIASES IN DOMESTIC DOGS IN A RURAL AREA OF THE MUNICIPALITY OF SÃO JOÃO DO PIAUÍ, PIAUÍ STATE, BRAZIL
SUMMARY Chagas disease and the leishmaniases are endemic zoonoses of great importance to public health in the state of Piauí, Brazil. The domestic dog (Canis familiaris) is a major reservoir, host of Trypanosoma cruzi and Leishmania spp. in both urban and rural areas, playing an important role in the transmission of these parasites. The present study evalua

4. Phlebotomine sandfly (Diptera: Psychodidae) diversity and their Leishmania DNA in a hot spot of American Cutaneous Leishmaniasis human cases along the Brazilian border with Peru and Bolivia
In this study, we identified the phlebotomine sandfly vectors involved in the transmission of American Cutaneous Leishmaniasis (ACL) in Assis Brasil, Acre, Brazil, which is located on the Brazil-Peru-Bolivia frontier. The genotyping of Leishmania in phlebotomines was performed using polymerase chain reaction (PCR) and PCR-restriction fragment length polymorp

5. Molecular detection of Trypanosoma sp. and Blastocrithidia sp. (Trypanosomatidae) in phlebotomine sand flies (Psychodidae) in the Federal District of Brazil
Abstract: INTRODUCTION : This study describes the occurrence of trypanosomatids in phlebotomines in Brasília, Brazil. METHODS : Two hundred and ten females of 13 sand fly species were analyzed by polymerase chain reaction (PCR) using different molecular markers (D7 24Sα rRNA, kDNA, and ITS1) and sequencing. RESULTS : PCR revealed trypanosomatid-positive

6. Natural infection of phlebotomines (Diptera: Psychodidae) by Leishmania (Leishmania) amazonensis in an area of ecotourism in Central-Western Brazil
AbstractBackground Bonito municipality, known as an area of ecoturism, in Mato Grosso do Sul state, Brazil, is also a focus of visceral and cutaneous leishmaniases, with cases registered in both human and canine populations. This study sought to investigate natural infection by flagellate forms of Leishmania in phlebotomines of the urban area of Bonito.Findi

7. Phlebotomine fauna, natural infection rate and feeding habits of Lutzomyia cruzi in Jaciara, state of Mato Grosso, Brazil
Visceral leishmaniasis (VL) in Brazil is transmitted by the phlebotomine Lutzomyia longipalpis and in some midwestern regions by Lutzomyia cruzi. Studies of the phlebotomine fauna, feeding habits and natural infection rate by Leishmania contribute to increased understanding of the epidemiological chain of leishmaniases and their vectorial capacity.

8. Lutzomyia whitmani is the main vector of American Cutaneous Leishmaniasis in the Brazilian Federal District and the most prevalent species in residential areas of the Administrative Region of Sobradinho
Although cases of cutaneous Leishmaniasis have been reported in Brasilia - DF, its mode of transmission is still unknown. Center of Disease Control traps (CDC trap) placed around Sobradinho, a periurban area in the Brazilian Federal District, were able to capture a sample of phlebotomines composed of 89% Lutzomyia whitmani, 7% Lu. bacula, and 3% Lu. davisi s

9. Estudo da capacidade vetorial de Migonemya migonei (França) e de Pintomya fischeri (Pinto) (Diptera: Psychodidae) para Leishmania (Leishmania) infantum chagasi Cunha &Chagas / Study of the vectorial capacity of Migonemyia migonei (França) and of Pintomyia fischeri (Pinto) (Diptera: Psychodidae) as regards Leishmania (Leishmania) infantum chagasi Cunha &Chagas
Introduction - Visceral leishmaniasis has been affecting canine and human populations in various urban centers in São Paulo state and the area of its distribution has been growing steadily. Since its introduction into the state, the infection has been identified in canine and feline populations of Greater São Paulo. Differently from other areas, where the

10. Diversity of sandflies (Psychodidae: Phlebotominae) captured in sandstone caves from Central Amazonia, Brazil
In the present paper we describe the diversity of phlebotomine sandflies collected in three sandstone caves in the municipality of Presidente Figueiredo, state of Amazonas, Brazil. The phlebotomines were captured during 2006 with CDC light traps. Guano samples from inside the Gruta Refúgio do Maruaga were collected to investigate the presence of immature sp

11. The effect of fragmentation on phlebotomine communities (Diptera: Psychodidae) in areas of ombrophilous forest in São Luís, state of Maranhão, Brazil
The aim of this study was to determine whether an edge effect could be observed in the structure and composition of phlebotomine assemblages in five forest fragments on São Luís Island. The study also investigated whether there were any differences in species along the forest edge-to-interior gradient and in species richness and abundance between the fragm

12. Pesquisa de Leishmania sp. em flebótomos e mamíferos silvestres de fragmentos florestais na região do Pontal do Paranapanema, SP / Survey of Leishmania sp in sandflies and mammals in forest fragments in the Pontal of Paranapanema region, SP
As alterações ambientais antrópicas são os principais fatores de emergência ou reemergência de doenças infecciosas. A leishmaniose cutânea é uma doença que está relacionada, em caráter epidêmico, com episódios de desmatamento. No entanto, o caráter endêmico da doença ocorre quando o homem se encontra próximo de áreas florestais já coloniz
