Three species of L. tropica, L. major and L. infantum are known as main causal agents of leishmaniasis have been reported in Iran. Since cutaneous leishmaniasis (CL) is endemic in North East of Iran, in the present work, 50 Leishmania positive isolates from human cases in Mashhad (Center of Razavi province, North East of Iran), were genotyped by means of polymerase chain reaction-restriction f...

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...

Phlebotomus perniciosus is one of the major vectors of Leishmania infantum in the Mediterranean basin. The aim of this work was (i) to provide information about abundance and temporal dynamics of this Larroussius species in a hot spot area of visceral leishmaniasis in Tunisia, (ii) to detect L. infantum DNA in wild caught female sandflies and (iii) to measure Phlebotomus perniciosus infection r...

Leishmania infantum and Leishmania donovani both pertain to the L. (L.) donovani complex and are responsible for visceral leishmaniasis. To explore the L. donovani complex, we focused our study on cysteine protease B (cpb) and especially on 2 cpb copies: cpbE and cpbF. We selected cpb genes because of their phylogenetic interest and host-parasite interaction involvement. Sequencing these 2 copi...

background: visceral leishmaniasis (vl) has strong links with poverty, substantial medical and veterinary impacts. this review aimed to focus in studies published during 1994-2016 on vl in southeastern iran. methods : the present review is based on expert knowledge and historical studies published during the past 23 yr (1994-2016) on vl in southeastern iran. in addition, related literature foun...

this study aimed to evaluate freeze-dried sera as an alternative to non-freeze dried for detection of anti-leishmania infantum antibodies over the course of 11 months using the direct agglutination test (dat).altogether, 60 serum samples (30 from humans and 30 from dogs) were collected from various geographical locations in iran. all the collected sera were pooled and each pooled serum sample c...

Zoonotic visceral leishmaniasis is caused by the protozoan Leishmania infantum and little is known about the occurrence and pathogenesis of this parasite in the CNS. The aims of this study were to evaluate the occurrence, viability and load of L. infantum in the CNS, and to identify the neurological histological alterations associated with this protozoan and its co-infections in naturally infec...

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 ...

Leishmaniasis is a neglected disease responsible for about 56,000 deaths every year. Despite its importance, there are no effective, safe and proper treatments for leishmaniasis due to strain resistance and/or drug side-effects. In this work we report the synthesis, molecular modeling, cytotoxicity and the antileishmanial profile of a series of 4-(1H-pyrazol-1-yl)benzenesulfonamides. Our exper...

In the north of Algeria, Leishmania infantum is responsible for two clinical forms of leishmaniasis: visceral and cutaneous leishmaniasis, for which dogs are the only proven reservoir host. In this study, the authors report, for the first time, the isolation of L. infantum from a golden jackal (Canis aureus) trapped in the Illoulen ou Malou region (Grande Kabylie). Two isolates were thus obtain...
