accuracy and reproducibility of a rapid chromatographic immunoassay for the diagnosis of canine visceral leishmaniasis in brazil.visceral leishmaniasis is a major public health concern in brazil and the domestic dog is the main source of infection. in this study, we aimed to evaluate the accuracy and reliability of a rapid chromatographic immunoassay based on a dual-path platform for the diagnosis of canine visceral leishmaniasis (cvl).201425015665
molecular identification of lutzomyia migonei (diptera: psychodidae) as a potential vector for leishmania infantum (kinetoplastida: trypanosomatidae).visceral leishmaniasis (vl) in brazil is caused by the protozoan leishmania infantum. this parasite is transmitted by the bite of a female sand fly. the most important sand fly species in vl transmission is lutzomyia longipalpis. in fortaleza, the capital of ceará state, brazil, the simultaneous occurrence of lutzomyia migonei and l. longipalpis was detected in localities where vl transmission is observed. the purpose of this study was to determine conclusively if l. migonei can be found natural ...201626995718
genetic structuring and fixed polymorphisms in the gene period among natural populations of lutzomyia longipalpis in brazil.even one hundred years after being originally identified, aspects of the taxonomy of the sand fly lutzomyia longipalpis, the principal vector of leishmania infantum in the americas, remain unresolved for brazilian populations of this vector. the diversity of morphological, behavioral, biochemical, and ethological characters, as well as the genetic variability detected by molecular markers are indicative of the presence of a complex of species.201525889567
