Infecção natural de Lutzomyia (Lutzomyia) longipalpis (Diptera: Psychodidae) por Leishmania infantum chagasi em flebotomíneos capturados no município de Janaúba, Estado de Minas Gerais, Brasil

Abstract: INTRODUÇÃO: A leishmaniose visceral tem sido notificada em quase todos os estados do Brasil, e principalmente no norte de Minas Gerais, onde a doença é endêmica. Este estudo visou detectar a infecção natural de Lutzomyia longipalpis e identificar através da técnica de PCR/RFLP a espécie de Leishmania encontrada nos flebotomíneos do município de Janaúba. MÉTODOS: Utilizando-se armadilhas luminosas, foram capturadas 1.550 fêmeas de L. longipalpis, que agrupadas em pool de 10 exemplares foram submetidas à extraçã… Show more

“…Although the incidence of VL in Rondônia has been exclusively associated with allocthonous cases (0.07 per 100 thousand inhabitants) 28 , the presence of L. longipalpis should be a factor of concern as, in the Amazon region, VL is already autochthonous in the States of Pará, Roraima, and Tocantins 22,29,30 and areas of the Southeast of Brazil, that were not traditional endemic areas of VL, had registered several autochthonous cases over the last ten years 22,30,31 . On the other hand, according to serologic studies performed in Monte Negro 8 , infected dogs and phlebotomine sandflies are in contact as dogs were found to be serologically positive for Leishmania.…”

“…chagasi, were captured in the Janaúba, which is an area of intense transmission of VL. Janaúba is similar to Barcarena with respect to environmental alterations, which can be described by rapid and intense rural population migration to an urban periphery that lacks adequate housing and sanitation infrastructure (Michalsky et al 2011).…”

“…Others have been detected with Leishmania DNA, such as Evandromyia Lenti , Evandromyia termitophila (Martins, Falcão & Silva, 1964), Micropygomyia ferreirana (Barreto, Martin & Pellegrino, 1956) and Ps . Lloydi [48,49,50,51,52,36,53,54,55,56,57], which may suggest they play a role in maintaining the parasite transmission cycle in wild environments.…”
