Leishmania infantum (syn. Leishmania chagasi) detection in blood donors living in an endemic area

Parasitology Research, 2022
Human visceral leishmaniasis (HVL) is a neglected disease that occurs in 98 countries on five continents, and it is endemic in tropical and subtropical regions. In South America, the etiological agent of HVL is Leishmania infantum (syn. Leishmania chagasi), mainly transmitted through the bite of an infected sandfly female from the genus Lutzomyia.

Detection of Leishmania (Leishmania) amazonensis and Leishmania (Leishmania) infantum chagasi in Brazilian bats

Veterinary Parasitology, 2010
Although bats are one of the most abundant mammals in the new world and are present in virtually all ecosystems, including urban and peri-urban environments, few studies have investigated the role of these animals in the epidemiological chain of leishmaniosis.

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.

Validation of a Leishmania infantum ELISA rapid test for serological diagnosis of Leishmania chagasi in dogs

Veterinary Parasitology, 2011
Canine visceral leishmaniasis (CVL) is caused by Leishmania donovani complex parasites including L. donovani, Leishmania infantum and Leishmania chagasi. As some studies suggest that L. chagasi and L. infantum may be very similar or even the same species, the aim of the present study was to evaluate a commercial rapid ELISA test, originally designed ...

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 ...

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.

Further thoughts on “Asymptomatic dogs are highly competent to transmit Leishmania (Leishmania) infantum chagasi to the natural vector”

Veterinary Parasitology, 2014
Asymptomatic or infect dog, symptomatic or sick/severely sick dog: the nomenclature did not change the clinical pathological classification in canine leishmaniasis.
