Dogs with divergent serology for visceral leishmaniasis as sources of Leishmania infection for Lutzomyia longipalpis phlebotomine sand flies – an observational study in an endemic area in Brazil

PLoS Neglected Tropical Diseases, 2020
Visceral leishmaniasis (VL) is a neglected tropical disease, caused by Leishmania (Kinetoplastida, Trypanosomatidae) species. In Brazil, the transmission of this parasite essentially occurs through the bite of Lutzomyia longipalpis (Diptera: Psychodidae:

Isozymic and metric variation in the Lutzomyia longipalpis complex

Medical and Veterinary Entomology, 1997
Abstract Male Lutzomyia longipalpis of two types from Bolivia were compared using isozyme electrophoresis and wing morphometry. One sample (ex Chiflonkaka Cave, alt. 2800 m at Toro Toro, Charcas Province, Potosi Department) was ‘two‐spot’ phenotype males (i.e. tergites III and IV with paired pale patches of pheromone glands), whereas two other locality

The Gut Microbiome of the Vector Lutzomyia longipalpis Is Essential for Survival of Leishmania infantum

mBio, 2017
The vector-borne disease leishmaniasis, caused by Leishmania species protozoa, is transmitted to humans by phlebotomine sand flies. Development of Leishmania to infective metacyclic promastigotes in the insect gut, a process termed metacyclogenesis, is ...

The First Instar Larva of Lutzomyia longipalpis (Diptera: Phlebotomidae) [PDF]

Memórias do Instituto Oswaldo Cruz, 1997
The morphology and chaetotaxy of the first instar larva of Lutzomyia (Lutzomyia) longipalpis are described based on observations made under scanning electron microscope. Because three-dimensional images were studied, some terminological changes are proposed to give a more realistic description of the positions of the setae.

Prostaglandin E2/Leukotriene B4 balance induced by Lutzomyia longipalpis saliva favors Leishmania infantum infection

Parasites & Vectors, 2014
Background Eicosanoids and sand fly saliva have a critical role in the Leishmania infection. Here, we evaluated the effect of Lutzomyia longipalpis salivary gland sonicate (SGS) on neutrophil and monocyte recruitment and activation of eicosanoid ...
