Background: Cutaneous Leishmaniasis, is endemically observed in different parts of Iran in two forms of anthroponotic and zoonotic. The identification of both species and the type of disease are beneficial for treatment and prevention. Microscopic identification of Leishmania species has not provided promising efficacy. The aim of this study was to determine the Le...

Cutaneous leishmaniasis is one of the most important parasitic diseases, which are endemic in different parts of Iran. Leishmania major and L. tropica are the primary causative agents of this disease. The aim of the present study was to detect the multiple forms of L. major in lung. Ppromastigotes of L. major at stationary phase were injected to BALB/c mice. After 60 days, the different forms o...

Background: Monoclonal antibodies have been employed extensively for the identification of Leishmania species, development of diagnostic tests and in the characterization of defined leishmanial antigens. Objectives: Identification and characterization of  Leishmania spp. directly from cutaneous lesions of infected individuals. Methods: An immunoperoxidase test (Avidin-Biotin technique) using mo...

Mixed infections with different Leishmania species could explain differences in the clinical courses of these infections. On identification of Leishmania parasites from Iranian patients with mucosal leishmaniasis (ML), a patient with both oral and nasal lesions was found to be concomitantly infected with Leishmania tropica and L. major. Mixed infection was identified by PCR amplification of Lei...

The outcome of Leishmania infections is determined by both the parasite species and the host genetic makeup. While much has been learned regarding immune responses to this parasite, our knowledge on parasite-derived factors is limited. The recent completion of the L. major and L. infantum genome sequence projects and concurrent advancement in proteomics technology would greatly accelerate the s...

Protozoan parasites of the genus Leishmania alternate between flagellated, elongated extracellular promastigotes found in insect vectors, and round-shaped amastigotes enclosed in phagolysosome-like Parasitophorous Vacuoles (PVs) of infected mammalian host cells. Leishmania amazonensis amastigotes occupy large PVs which may contain many parasites; in contrast, single amastigotes of Leishmania ma...

background : historically, leishmanization is the most effective protective measure against cutaneous leishmaniasis (cl), cl lesion induced by leishmanization sometimes takes a long time to heal. ma­nipulation of leishmanization inoculums needed to induce a mild and acceptable cl lesion. the aim of this study was to explore if liposomal form of cpg odn (cytosin phosphate guanin oligodeoxynu­cle...

background: cutaneous and visceral leishmaniases are present in fars province in the south of iran. the current study aimed to evaluate the inter- and intragenic diversities of leishmania species isolated from patients with leishmaniasis in fars province, using pcr-based analyses and dna sequencing of  the n-acetylglucosamine-1-phosphate transferase ( nagt ) gene. methods: clinical samples were...

Background: Cutaneous and visceral leishmaniases are present in Fars Province in the south of Iran. The current study aimed to evaluate the inter- and intragenic diversities of Leishmania species isolated from patients with leishmaniasis in Fars Province, using PCR-based analyses and DNA sequencing of  the N-acetylglucosamine-1-phosphate transferase (nagt) gene.Methods: Clinical samples were ta...

Background: Zoonotic cutaneous leishmaniasis (ZCL) due to Leishmania major is increasing in many parts of Iran. This disease originally is a disease found in gerbils. Leishmania parasites are transmitted by sandflies that live and breed in gerbil burrows. Nested PCR amplified Leishmania ITS1-5.8S rRNA gene in both main reservoir host “Rhombomys opimus” and in the “Phlebotomus papatasi” main vec...
