ABSTRACT Background and Objectives: Due to adverse effects of pentavalent antimonial treatment of visceral leishmaniasis using herbal medicines has received a lot of attention. In this study, we evaluated inhibitory activity of Pelargonium roseum essential oil on growth of Leishmania infantum promastigotes, and compared it with that ...
Leishmania infantum causes visceral leishmaniasis (VL) in the New World. The diagnosis of VL is confirmed by parasitological and serological tests, which are not always sensitive or specific. Our aim was to design new primers to perform a Polymerase Chain Reaction (PCR) for detecting L. infantum. Sequences of the minicircle kinetoplast DNA (kDNA) were obtained from GenBank, and the FLC2/RLC2 pr...
BACKGROUND Visceral leishmaniasis (VL) is a protozoan diseases caused in Europe by Leishmania (L.) infantum. Asymptomatic Leishmania infection is more frequent than clinically apparent disease. Among HIV infected patients the risk of clinical VL is increased due to immunosuppression, which can reactivate a latent infection. The aims of our study were to assess the prevalence of asymptomatic L. ...
INTRODUCTION Canine exposure to Lutzomyia longipalpis bites and the potential of Leishmania infantum transmissibility for the vector were evaluated. METHODS Immunoglobulin G (IgG) anti-Lu longipalpis saliva and -L. infantum, and blood parasite load were determined in dogs from endemic areas of visceral leishmaniasis. RESULTS Blood parasitism was similar between symptomatic and asymptomatic ...
BACKGROUND Visceral Leishmaniasis (VL) caused by species from the Leishmania donovani complex is the most severe form of the disease, lethal if untreated. VL caused by Leishmania infantum is a zoonosis with an increasing number of human cases and millions of dogs infected in the Old and the New World. In this study, L. infantum (syn. L.chagasi) strains were isolated from human and canine VL cas...
BACKGROUND & OBJECTIVES Kala-azar is the visceral and most severe form of leishmaniasis that leads to death if untreated. The causative agents of visceral leishmaniasis (VL) are members of Leishmania (L.) donovani complex which includes L. chagasi and L. infantum. Genome sequences have raised the question whether L. chagasi and L. infantum are synonymous or different. This question has importan...
BACKGROUND Leishmania infantum is a flagellated protozoan parasite that is able to parasitize blood and tissue. Leishmania species cause a spectrum of clinical disease with cutaneous, visceral or mucosal involvement. L. infantum is recognised as a cause of visceral leishmaniasis (VL) and is less commonly reported as a cause of cutaneous leishmaniasis (CL) from countries around the Mediterranean...
Visceral leishmaniasis (VL) is an emerging zoonosis disease in countries of the Mediterranean basin caused by Leishmania infantum. Although domestic dogs are the main vertebrate hosts, many wild carnivores have been considered playing a role in the spreading of VL. Sporadic numbers of dog and human VL have been reported in Golestan Province in North Iran. The present study was performed to dete...
Objective(s): Leishmaniasis is endemic in 88 countries. Amastigote forms of Leishmania are experts at exploiting host cell processes to establish infection. Monoclonal antibodies are key reagents used in the diagnosis of infectious and non-infectious diseases. The aim of this study was to produce monoclonal antibodies against axenic amastigotes of the Leishmania infantum strain in Iran.Material...
Ecto-nucleotidase activity is involved in the infection process of Leishmania and various other parasites that enables modulation of host immune responses to promote disease progression. One of the enzymes responsible for this activity is the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase). The enzyme hydrolyzes nucleotides tri- and/or di-phosphate into monophosphate products, which...
