First molecular detection of Leishmania (Leishmania) infantum chagasi in a domestic cat (Felis catus) from an urban area in eastern Amazon [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 2023
Background: Domestic cats have been implicated as accidental hosts of Leishmania sp. However, in recent years, the recurrent description of new cases in endemic and nonendemic areas draw attention to the potential epidemiological role of cats as ...

Inhibition of trypsin expression in Lutzomyia longipalpis using RNAi enhances the survival of Leishmania [PDF]

, 2009
Background Leishmania parasites must overcome several barriers to achieve transmission by their sand fly vectors. One of the earliest threats is exposure to enzymes during blood meal digestion.

Chicken blood provides a suitable meal for the sand fly Lutzomyia longipalpis and does not inhibit Leishmania development in the gut [PDF]

, 2010
Background The aim of this study was to address the role of chickens as bloodmeal sources for female Lutzomyia longipalpis and to test whether chicken blood is harmful to Leishmania parasite development within the sand flies.

Investigation of the bacterial communities associated with females of Lutzomyia sand fly species from South America [PDF]

, 2012
Phlebotomine sand flies are vectors of Leishmania that are acquired by the female sand fly during blood feeding on an infected mammal. Leishmania parasites develop exclusively in the gut lumen during their residence in the insect before transmission to a

Imidazolium salts as an alternative for anti-Leishmania drugs: Oxidative and immunomodulatory activities

Frontiers in Immunology, 2023
In this study we explored the previously established leishmanicidal activity of a complementary set of 24 imidazolium salts (IS), 1-hexadecylimidazole (C16Im) and 1-hexadecylpyridinium chloride (C16PyrCl) against Leishmania (Leishmania) amazonensis and ...

The first case report of Leishmania (leishmania) chagasi in Panthera leo in Brazil [PDF]

Asian Pacific Journal of Tropical Biomedicine, 2011
We reported here the first known case of natural infection of a lion (Panthera leo-Linnaeus, 1758) with Leishmania (Leishmania) chagasi (L. chagasi) in Brazil. The specimen was created by a circus handler in the state of Mato Grosso and was donated to the zoological park of the Federal University of Mato Grosso. Infection by L.

Visualisation of Leishmania donovani fluorescent hybrids during early stage development in the sand fly vector. [PDF]

, 2011
BACKGROUND: The Leishmania protozoan parasites cause devastating human diseases. Leishmania have been considered to replicate clonally, without genetic exchange.
