BACKGROUND Since Pars Abad district had been known as a focus of visceral leishmaniasis (VL) in Ardabil Province but the prevalence of the disease in nomadic tribes has not been determined, thus, this study was conducted. METHODS This descriptive cross-sectional study was conducted on children up to 12yr old of nomadic tribes from Pars Abad County, Ardabil Province, Iran in 2015. For each ind...
The authors report the identification of Leishmania strains isolated from the Centre and the South of Tunisia. 266 strains were isolated between 1998 and 2006 from human (n=221 strains) and dogs (n=45 strains) hosts. The isoenzymatic identification exhibits the presence of in total five zymodemes belonging to three Leishmanio complexes: Leishmania infantum, L. major and L. killicki. All strains...
The search for new treatments against leishmaniasis has increased due to high frequency of drug resistance registered in endemics areas, side effects, and complications caused by coinfection with HIV. Morinda citrifolia Linn., commonly known as Noni, has a rich chemical composition and various therapeutic effects have been described in the literature. Studies have shown the leishmanicidal activ...
Infection by Leishmania species is increasing worldwide. It was hypothesized recently that cats act as a secondary reservoir for Leishmania infection. The aim of the present study was to assess the prevalence of Leishmania infantum antibodies and DNA in blood samples collected in a sample of stray cats in metropolitan area of Milan in northern Italy, which is a nonendemic area for leishmaniasis...
BACKGROUND Leishmania infantum recently has been identified as a possible agent of cutaneous leishmaniasis (CL). This species has been isolated from cutaneous lesions of patients from the Mediterranean Basin. However, little is known about the clinical, biological, or therapeutic features of this newly recognized CL. OBSERVATIONS Six patients aged 9 months to 85 years in southeastern France w...
Leishmania infantum is one of the major parasite species associated with visceral leishmaniasis, a severe form of the disease that can become lethal if untreated. This obligate intracellular parasite has developed diverse strategies to escape the host immune response, such as exoproducts (Exo) carrying a wide range of molecules, including parasite virulence factors, which are potentially implic...
Extracellular factors produced by Leishmania spp., Trypanosoma cruzi, and Trypanosoma brucei are important in the host-parasite relationship. Here, we describe a genome-based approach to identify putative extracellular proteins conserved among trypanosomatids that are likely involved in the classical secretory pathway. Potentially secreted proteins were identified by bioinformatic analysis of t...
At present it is not possible to determine in advance the outcome of Leishmania infantum infection. Canine Visceral Leishmaniasis (VL), caused by Le. infantum, is a natural disease process which offers a insight into the interaction of the host and resultant disease outcome. Canine VL results in the same altered pathophysiology and immunodysregulation seen in humans. VL in US dogs is likely to ...
Here we engineered transgenic Leishmania infantum that express luciferase, the objectives being to more easily monitor in real time their establishment either in BALB/c mice--the liver and spleen being mainly studied-or in vitro. Whatever stationary phase L. infantum promastigotes population--wild type or engineered to express luciferase-the parasite burden was similar in the liver and the sple...
The aim of this study was to assess histological alterations and perform immunolabeling of Leishmania infantum in the kidneys and urinary bladder of naturally infected dogs. Twenty-five urinary bladder and kidney samples of serologically positive animals (ELISA S7® Biogene and IFAT ≥ 1:40 - Biomanguinhos/Fiocruz) were analyzed by means of immunohistochemical and histological techniques. Cystiti...
