[distribution of vectors of visceral leishmaniasis in the province of corrientes, 2008].visceral leishmaniasis (vl) is a relevant parasitic disease in public health, produced by leishmania infantum chagasi. since the urbanization and emergence in southern brazil and paraguay, the vector lutzomyia longipalpis in formosa, 2004, and the first human visceral leishmaniasis case in misiones, 2006, have been reported in argentina. due to the reports of canine vl, a search of the vector in the province of corrientes, contiguous to misiones, was performed during december 2008. standarized t ...200920053601
detection of leishmania infantum in naturally infected lutzomyia longipalpis (diptera: psychodidae: phlebotominae) and canis familiaris in misiones, argentina: the first report of a pcr-rflp and sequencing-based confirmation this study, a genotypification of leishmania was performed using polimerase chain reaction-restriction fragment length polymorphism (pcr-rflp) and sequencing techniques to identify species of leishmania parasites in phlebotomine sand flies and dogs naturally infected. between january-february of 2009, cdc light traps were used to collect insect samples from 13 capture sites in the municipality of posadas, which is located in the province of misiones of argentina. sand flies identified as lutz ...201020944995
first comparative transcriptomic analysis of wild adult male and female lutzomyia longipalpis, vector of visceral leishmaniasis.leishmaniasis is a vector-borne disease with a complex epidemiology and ecology. visceral leishmaniasis (vl) is its most severe clinical form as it results in death if not treated. in latin america vl is caused by the protist parasite leishmania infantum (syn. chagasi) and transmitted by lutzomyia longipalpis. this phlebotomine sand fly is only found in the new world, from mexico to argentina. however, due to deforestation, migration and urbanisation, among others, vl in latin america is undergo ...201323554910
identification of leishmania infantum in puerto iguazú, misiones, argentina.the emergence of zoonotic visceral leishmaniasis (zvl) in latin america is a growing public health problem. the urbanization of zvl has been observed in different countries around the world, and there are a growing number of reports drawing attention to the emergence of this infection in new locations, as well as its increase in previously established areas of endemicity. in the city of posadas, misiones province, northeastern argentina, the transmission of zvl associated with canines and lutzom ...025923899
a canine leishmaniasis pilot survey in an emerging focus of visceral leishmaniasis: posadas (misiones, argentina).an increasing number of reports are calling our attention to the worldwide spread of leishmaniasis. the urbanization of zoonotic visceral leishmaniasis (vl) has been observed in different south american countries, due to changes in demographic and ecological factors. in may 2006, vl was detected for the first time in the city of posadas (misiones, argentina). this event encouraged us to conduct a clinical and parasitological pilot survey on domestic dogs from posadas to identify their potential ...201021122107
field evaluation of a new strategy to control lutzomyia longipalpis, based on simultaneous application of an adulticide-larvicide mixture.leishmania infantum (syn. chagasi) is the etiologic agent of visceral leishmaniasis in argentina, and the phlebotomine fly lutzomyia longipalpis is its main vector. the objective of this study was to evaluate the effectiveness of dragon max(®), an emulsifiable concentrate formulation containing the pyrethroid permethrin and the larvicide pyriproxyfen, for lu. longipalpis control under field conditions. the work was conducted in the city of posadas (misiones province, argentina). comparisons were ...201627802395
leishmania infantum dna detected in phlebotomine species from puerto iguazú city, misiones province, puerto iguazú city, argentina, human and canine visceral leishmaniasis cases have been recorded since the year 2010, with leishmania infantum as the etiological agent and lutzomyia longipalpis as its main vector. in the present study, polymerase chain reaction and sequencing were used to detect l. infantum dna in 3.9% of the female sandflies captured in puerto iguazú city. this is the first report of l. infantum dna detection in micropygomyia quinquefer, and the second one in lu. longipalpis ...201728476601
