UNLABELLED Viscerotropic leishmaniasis (VTL) is a parasitic disease with non-specific manifestations caused by Leishmania tropica. Specific antigens produced by Viscerotropic leishmaniasis gene have been used for diagnosis of VTL. The aim of this study was to compare the expression level of VTL gene among the viscerotropic L. tropica isolates (n: 3) and visceral L. infantum isolates (n: 4). Als...

Leishmaniasis represents a serious threat to the health as one of the most important neglected tropical diseases as designated by the World Health Organization. The disease is endemic in 82 countries, among them Tunisia is an indigenous area for cutaneous Leishmaniasis. In a previous work, two tritepenic acids namely oleanolic and maslinic acids have been isolated from olive leaf extract. In th...

Visceral leishmaniasis (VL) is a serious and fatal disease. Therapeutic drugs are toxic and non-sterilizing. The etiological agents Leishmania infantum and Leishmania donovani cause active and asymptomatic diseases. Effective drugs to treat VL exist but unfortunately, post-treatment relapses are common. Little is known why drugs are non-sterilizing or how these intracellular pathogens can escap...

The Leishmania (Leishmania) donovani nucleoside hydrolase NH36 is the main antigen of the Leishmune® vaccine and one of the promising candidates for vaccination against visceral leishmaniasis. The antigenicity of the N-terminal (F1), the central (F2), or the C-terminal recombinant domain (F3) of NH36 was evaluated using peripheral blood mononuclear cells (PBMC) from individuals infected with L....

New prevention and treatment strategies are needed for visceral leishmaniasis, particularly ones that can be deployed simply and inexpensively in areas where leishmaniasis is endemic. Synthetic molecules that activate Toll-like receptor 7 and 8 (TLR7/8) pathways have previously been demonstrated to enhance protection against cutaneous leishmaniasis. We initially sought to determine whether the ...

background: heat shock protein 70 (hsp70) is present in all organisms studied so far, and is a major immunogen in infections caused by pathogens including leishmania spp. objective: the aim of this study was to clone and express hsp70 from l. infantum strain mcan/ir/96/lon-49 and evaluate antibody response against hsp70 in visceral leishmaniasis (vl). methods: the l. infantum hsp70 gene segment...

The southern habitats of Croatia's gray wolf (Canis lupus) population are found in central and southern parts of Dalmatia. This region is recognized as an endemic region for canine visceral leishmaniosis, caused by Leishmania infantum. In November 2003, a 4-yr-old male gray wolf was found dead in the northwestern border of this endemic region. Pathologic and parasitologic analysis, confirmed by...

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...
