purpose: evaluation of humoral and cellular immune responses of naturally infected dogs against type i (rcpb) (recombinant cycsteine proteinase b), and ii (rcpa) (recombinant cycsteine proteinase a) recombinant cysteine proteinases and c-terminal extension (cte) of leishmania infantum (l. infantum). materials and methods: in this study, fourteen infected dogs (7 with symptoms, 7 asymptomatics)...
Over the last decade, the incidence of visceral leishmaniasis (VL) has increased in many districts of the province of Fars, in southern Iran. Recent epidemiological reports indicate that asymptomatic human infections with Leishmania infantum (the causative agent of VL throughout the Mediterranean basin) occur more frequently in Iran than was previously believed. Between 2004 and 2006, blood sam...
Leishmania infantum, causative agent of visceral leishmaniasis in humans, illustrates a complex lifecycle pertaining to two extreme environments, namely, the gut of the sandfly vector and human macrophages. Leishmania is capable of dynamically adapting and tactically switching between these critically hostile situations. The possible metabolic routes ventured by the parasite to achieve this exc...
BACKGROUND Phlebotomus tobbi is a vector of Leishmania infantum, and P. sergenti is a vector of Leishmania tropica. Le. infantum and Le. tropica typically cause visceral or cutaneous leishmaniasis, respectively, but Le. infantum strains transmitted by P. tobbi can cause cutaneous disease. To better understand the components and possible implications of sand fly saliva in leishmaniasis, the tran...
background: visceral leishmaniasis is caused by leishmania infantum , transmitted to humans by bites of phlebotomine sand flies and is one of the most important public health problems in iran. to identify the vector(s), an investigation was carried out in bilesavar district, one of the important foci of the disease in ardebil province in northwestern iran, during july - september 2008 . meth...
background: cutaneous leishmaniasis (cl) is endemic in southeastern anatolia, mainly in sanliurfa and hatay provinces, and the causative agents are mostly leishmania tropica and less frequently l. infantum . here, we report the first mal-di-tof analyses of leishmania promastigotes obtained from the cultures of two cl cases from osmaniye and hatay provinces who were initially diagnosed by micros...
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 in...
Background: Canine visceral leishmaniasis (CVL) caused by Leishmania infantum is endemic in the northwest and south of Iran. An appropriate vaccine can help to prevent and control visceral leishmaniasis in both humans and animals. Few studies have confirmed that the fucose-mannose ligand (FML) antigen of Leishmania donovani produced protective immunity in dogs against CVL. Objective: To evaluat...
Leishmaniasis is a tropical parasitic infection. The resistance and toxicity issues are the major complications and remain significant consequences related to the treatment of leishmaniasis with the recent and classical drugs. Thus there is an immediate requirement to develop new compounds for the treatment of this protozoan disease. Sea cucumbers or holothurians are potentially presented as th...
BACKGROUND The development of cost-effective prophylactic strategies to prevent leishmaniasis has become a high-priority. The present study has used the phage display technology to identify new immunogens, which were evaluated as vaccines in the murine model of visceral leishmaniasis (VL). Epitope-based immunogens, represented by phage-fused peptides that mimic Leishmania infantum antigens, wer...
