1. Clinical aspects and diagnosis of leishmaniasis in equids: a systematic review and meta-analysis
Resumo As leishmanioses são um grupo de doenças de importância zoonótica causadas por mais de 20 espécies de protozoários do gênero Leishmania, sendo o cão doméstico considerado o principal reservatório da doença. No entanto, diversas pesquisas têm investigado o envolvimento de outros vertebrados como reservatórios do parasita. Portanto, o objet

2. Molecular detection of Leishmania spp. in cattle from Brazil by means of PCR using internal transcribed spacer 1
Resumo Leishmania spp. são agentes causadores das leishmanioses em humanos e em animais, gerando grande impacto à saúde pública. Este estudo objetivou detectar a circulação de Leishmania spp. em área não endêmica para leishmaniose visceral de São Paulo, Brasil. Foram extraídas amostras de DNA de 100 novilhas da cidade de Pirassununga. Estas amostr

3. Development of Leishmania mexicana in Lutzomyia longipalpis in the absence of sugar feeding
The leishmaniases are caused by Leishmania parasites and transmitted through the bites of phlebotomine sand flies. During parasite development inside the vector’s midgut, promastigotes move towards the stomodeal valve, a mechanism that is crucial for transmission. It has been reported that the sugar meal acquired by sand flies during feeding between bloodm

4. Chicken eggs as a surveillance tool for malaria and leishmaniasis vector presence
Abstract INTRODUCTION: Malaria and leishmaniases are transmitted by vectors during blood-feeding. Vector-infected animals develop antibodies against the vector’s saliva. This study evaluated IgY antibody detection in the chicken eggs exposed to bites from Migonemyia migonei, Lutzomyia longipalpis and Anopheles aquasalis. METHODS: We used ELISA to quant

5. Standardization and evaluation of a duplex real-time quantitative PCR for the detection of Leishmania infantum DNA: a sample quality control approach
Abstract INTRODUCTION: Molecular techniques have been shown to be alternative methods for the accurate detection of infectious and parasitic diseases, such as the leishmaniases. The present study describes the optimization and evaluation of a duplex real-time quantitative PCR (qPCR) protocol developed for the simultaneous detection of Leishmania infantum DN

6. Seasonality of sand flies (Diptera: Psychodidae) and Leishmania DNA detection in vector species in an area with endemic visceral leishmaniasis
BACKGROUND Leishmaniases are a serious health problem in southeast Brazil, including the city of Belo Horizonte (BH), Minas Gerais state (MG), where there are high rates of incidence and mortality due to visceral leishmaniases. BH is divided into nine sanitary districts (SD) of which one, the Venda Nova SD, was selected for this study because it has high r

7. 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

8. EVOLUTION OF AMERICAN TEGUMENTARY LEISHMANIASIS CASES REPORTED IN PARANÁ STATE, BRAZIL
SUMMARY Leishmaniases are infectious diseases caused by protozoa of the genus Leishmania. They are widely distributed worldwide and endemic in 88 countries in four continents. The present study analyzed the reported cases of American Tegumentary Leishmaniasis (ATL) in Paraná State (Brazil) from January 2007 to December 2013. The data were grouped according

9. 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

10. Studies on Phlebotominae (Diptera: Psychodidae) in the Campus FIOCRUZ Mata Atlântica, Jacarepaguá, in the City of Rio de Janeiro, Brazil
INTRODUCTION: The presence of American cutaneous leishmaniasis (ACL) in the communities of the Campus FIOCRUZ Mata Atlântica (CFMA) in the City of Rio de Janeiro initiated the investigation of the Phlebotominae fauna in the Atlantic Forest to determine the occurrence of putative ACL vectors associated with the enzootic cycle. METHODS: For 24 consecutive mo

11. 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.

12. Tissue distribution of residual antimony in rats treated with multiple doses of meglumine antimoniate
Meglumine antimoniate (MA) and sodium stibogluconate are pentavalent antimony (SbV) drugs used since the mid-1940s. Notwithstanding the fact that they are first-choice drugs for the treatment of leishmaniases, there are gaps in our knowledge of their toxicological profile, mode of action and kinetics. Little is known about the distribution of antimony in tis
