Asymptomatic dogs are highly competent to transmit Leishmania (Leishmania) infantum chagasi to the natural vector

Veterinary Parasitology, 2013
We evaluated the ability of dogs naturally infected with Leishmania (Leishmania) infantum chagasi to transfer the parasite to the vector and the factors associated with transmission. Thirty-eight infected dogs were confirmed to be infected by direct observation of Leishmania in lymph node smears.

Antiproliferative and ultrastructural effects of phenethylamine derivatives on promastigotes and amastigotes of Leishmania ( Leishmania ) infantum chagasi

Parasitology International, 2017
Leishmania (Leishmania) infantum chagasi is one of the agents that cause visceral leishmaniasis. This disease occurs more frequently in third world countries, such as Brazil. The treatment is arduous, and is dependent on just a few drugs like the antimonial derivatives and amphotericin B.

Importance of worldwide asymptomatic carriers of Leishmania infantum (L. chagasi) in human

Acta Tropica, 2011
Leishmaniasis due to Leishmania infantum (syn. L. chagasi) infection is a zoonotic disease present mainly in Mediterranean basin, central Asia and Brazil. Besides a limited number of human cases of clinical visceral leishmaniasis, a great number of infections remains asymptomatic. In this review, the prevalence of asymptomatic carriers of L.

Asymptomatic Leishmania infantum/chagasi infection in blood donors of western Sicily

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2008
The purpose of this study was to evaluate whether the risk of transfusion-transmitted visceral leishmaniasis was present in an area of western Sicily where the incidence of the disease is higher than the regional average. From May to December 2005, 1449 blood donors from Agrigento district (Sicily, Italy) were screened for the presence of anti ...

Infection by Leishmania (Leishmania) infantum chagasi causes intestinal changes B‐1 cells dependent

Parasite Immunology, 2019
AbstractEvaluating the histopathological and morphometric changes caused by Leishmania (Leishmania) infantum chagasi infection either in the presence or absence of B‐1 cells. Wild‐type Balb/c and XID mice were used. Half of XID mice received B‐1 cells adoptive transfer (XID + B1). Five animals from each group were infected (Balb/c I, XID I and XID + B1

The local inflammatory response to Leishmania chagasi infantum infection (134.89)

The Journal of Immunology, 2009
Abstract Leishmania chagasi infantum (Lci) causes human visceral leishmaniasis. To study the nature of the early inflammatory response, we introduced metacyclic wild type and mCherry-transgenic parasites intradermally in ears of BALB/c mice.

Anti-leishmanial activity of the antimicrobial peptide DRS 01 observed in Leishmania infantum (syn. Leishmania chagasi) cells

Nanomedicine: Nanotechnology, Biology and Medicine, 2014
Leishmaniasis is one of the most serious diseases in the world and can be lethal if untreated. This is especially the case for visceral leishmaniasis, which is commonly caused by Leishmania (L.) infantum and for which available medication is still inadequate. A recently described antimicrobial peptide DRS 01 has been reported to kill L.
