25. Isolation and Structural Characterization of Two New Furanoditerpenes from Pterodon emarginatus (Fabaceae)
A furanoditerpene-enriched fraction was obtained from the fruits of Pterodon emarginatus and submitted to semipreparative high performance liquid chromatography (HPLC). Two new furanoditerpenes, 6α,19β-diacetoxy-7β,14β-dihydroxyvouacapan and 6α-acetoxy-7β,14β-dihydroxyvouacapan, in addition to the known compound methyl 6α-acetoxy-7β-hydroxyvouacapan

26. Structural insights into leishmanolysins encoded on chromosome 10 of Leishmania (Viannia) braziliensis
BACKGROUND Leishmanolysins have been described as important parasite virulence factors because of their roles in the infection of promastigotes and resistance to host’s defenses. Leishmania (Viannia) braziliensis contains several leishmanolysin genes in its genome, especially in chromosome 10. However, the functional impact of such diversity is not under

27. Disseminated cutaneous leishmaniasis caused by Leishmania braziliensis in Southern Brazil
ABSTRACT The authors report a case of disseminated cutaneous leishmaniasis caused by Leishmania (Viannia) braziliensis, in a 55 years old patient with 1,119 lesions distributed throughout the body. The patient resides in Sabáudia municipality, North of Paraná State, Southern Brazil, where there was no previous report of this form of leishmaniasis. Treatmen

28. Sporotrichoid leishmaniasis: a cross-sectional clinical, epidemiological and laboratory study in Rio de Janeiro State, Brazil
ABSTRACT Background Atypical presentations of cutaneous leishmaniasis include sporotrichoid leishmaniasis (SL), which is clinically described as a primary ulcer combined with lymphangitis and nodules and/or ulcerated lesions along its pathway. Aims To assess the differences between patients with sporotrichoid leishmaniasis and typical cutaneous leishmani

29. 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

30. Achievement of constitutive fluorescent pLEXSY-egfp Leishmania braziliensis and its application as an alternative method for drug screening in vitro
BACKGROUND Gene reporter-fluorescent cells have emerged as alternative method for drug screening. OBJECTIVE Achievement of constitutive expression of fluorescent protein GFP by Leishmania braziliensis as alternative method for drug screening. METHODS L. braziliensis-GFP was generated using Leishmania tarentolae pLEXSY-egfp for constitutive expression of

31. First description of Leishmania (Viannia) infection in Evandromyia saulensis, Pressatia sp. and Trichophoromyia auraensis (Psychodidae: Phlebotominae) in a transmission area of cutaneous leishmaniasis in Acre state, Amazon Basin, Brazil
Studies on the sandfly fauna to evaluate natural infection indexes are still limited in the Brazilian Amazon, a region with an increasing incidence of cutaneous leishmaniasis. Here, by using a multiplex polymerase chain reaction directed to Leishmania kDNA and hybridisation, we were able to identify L. (Viannia) subgenus in 12 out of 173 sandflies captured i

32. Coinfecção com Hepatozoon canis e Leishmania spp. em cães diagnosticados com leishmaniose visceral
Resumo O presente estudo descreve a ocorrência de coinfecção com Hepatozoon canis e duas espécies de Leishmania (L. infantum ou L. braziliensis) em cães. Quatro cães sorologicamente diagnosticados com leishmaniose visceral foram eutanasiados. Amostras do baço e fígado foram submetidas à histopatologia e extração de DNA. Merontes de H. canis foram

33. Genomic and phylogenetic evidence of VIPER retrotransposon domestication in trypanosomatids
Transposable elements are important residents of eukaryotic genomes and eventually the host can domesticate them to serve cellular functions. We reported here a possible domestication event of the vestigial interposed retroelement (VIPER) in trypanosomatids. We found a large gene in a syntenic location in Leishmania braziliensis, L. panamensis, Leptomanas py

34. Evaluation of the antiplasmodial and leishmanicidal potential of Myrciaria dubia (Myrtaceae) extract
Abstract INTRODUCTION: Malaria and leishmaniasis are prevalent in tropical regions, which have environmental characteristics that are highly favorable to protozoa and vectors of these diseases; the transmission of these infections in sub-tropical regions, although recognized, represents only a small fraction of cases. Plants are constantly being used in the

36. 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
