Community deployment of a synthetic pheromone of the sand fly Lutzomyia longipalpis co-located with insecticide reduces vector abundance in treated and neighbouring untreated houses: Implications for control of Leishmania infantum

open access: yesPLoS Neglected Tropical Diseases, 2021
Background The rising incidence of visceral leishmaniasis due to Leishmania infantum requires novel methods to control transmission by the sand fly vector.

Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae): a review [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2003
Lutzomyia longipalpis is the most important vector of AmericanVisceral Leishmaniasis (AVL) due to Leishmania chagasi in the New World.

Ingestion of saliva during carbohydrate feeding by Lutzomyia longipalpis (Diptera; Psychodidae) [PDF]

open access: diamondMemórias do Instituto Oswaldo Cruz, 2006
The aim of this study was to obtain experimental evidence that phlebotomine saliva is actually ingested during the carbohydrate ingestion phase (before and after blood digestion). The ingestion of carbohydrate was simulated as it occurs in the field by offering the insects balls of cotton soaked in sucrose, sucrose crystals or orange juice cells.

Prevalence and incidence of canine visceral leishmaniasis and its clinical–immunological features in an endemic area of the Brazilian Amazon

open access: yesVeterinary Medicine and Science, Volume 9, Issue 6, Page 2463-2474, November 2023., 2023
The canine Leishmania (Leishmania) chagasi‐infection has a strong impact on the health of dogs by making a high number of dogs susceptible to visceral leishmaniasis before 2 years of age. The incidence of canine infection revealed that 6.6% of dogs/month acquire the infection before completing 1 year of life.

The first record of Lutzomyia longipalpis in the Argentine northwest [PDF]

open access: yesMemórias do Instituto Oswaldo Cruz, 2013
In 2004, the urban presence of Lutzomyia longipalpis was recorded for the first time in Formosa province. In 2006, the first autochthonous case of human urban visceral leishmaniasis (VL) was recorded in Misiones in the presence of the vector, along with some canine VL cases.

Leishmania amazonensis from distinct clinical forms/hosts has polymorphisms in Lipophosphoglycans, displays variations in immunomodulatory properties and, susceptibility to antileishmanial drugs

open access: yesCell Biology International, Volume 46, Issue 11, Page 1947-1958, November 2022., 2022
Abstract Lipophosphoglycan (LPG), the major Leishmania glycoconjugate, induces pro‐inflammatory/immunosuppressive innate immune responses. Here, we evaluated functional/biochemical LPG properties from six Leishmania amazonensis strains from different hosts/clinical forms.
