ABSTRACT Background and Objective: Cutaneous leishmaniasis is a parasitic disease and a health problem in different parts of Iran, especially two cities of Mashhad and Chabahar. Due to morphological similarities of most Leishmania species and difference in reservoirs of L. major and L. tropica, it is necessary to determine the parasite speci...
Leishmaniasis is the general denomination given to the infection caused by any species of the Leishmania protozoan genus transmitted in Europe, Asia and Africa by sand flies (Phlebotomus) and by species of Lutzomyia in America. It is endemic to the Mediterranean basin and its incidence has increased in recent years in connection with immunodepression status. It gives rise to 4 clinical syndrome...
Background and purpose: Iran is one of the endemic focuses of cutaneous leishmaniasis (CL) in the world. The disease is commonly seen in some tropical regions of Kermanshah province (West of Iran). In this study, patients with CL were diagnosed and identified using RFLP-PCR and DNA sequencing. Materials and methods: In this descriptive study all suspected cases of CL attended a clinic affili...
Leishmania species are protozoan parasites and the causative agents of leishmaniasis, a vector borne disease that imposes a large health burden on individuals living mainly in tropical and subtropical regions. Different Leishmania species are responsible for the distinct clinical patterns, such as cutaneous, mucocutaneous, and visceral leishmaniasis, with the latter being potentially fatal if l...
Background & Objectives: Leishmaniasis as a zoonosis disease seen in three forms including Cutaneous, mucocutaneous, and visceral (kala- azar). The Leishmania transferred by sand flies is the causative agent of this disease. Considering that leishmaniasis is an endemic disease in Fasa, this study was performed to determine the sand fly species of Fasa, Materials & Methods: In this cross- se...
detection and identification of leishmania parasites within sand flies using kdna, rdna and cpb loci
objective: molecular epidemiology of visceral leishmaniasis (vl) is currently used widely for different objectives such as vector incrimination studies. materials and methods: in this study three different loci including kinetoplast dna (kdna), ribosomal dna (rdna), and cystein protease b (cpb) of leishmania parasite genome were used for detection and identification of natural infection of san...
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...
Leishmania is a digenetic protozoan parasite causing leishmaniasis in humans. The different clinical forms of leishmaniasis are caused by more than twenty species of Leishmania that are transmitted by nearly thirty species of phlebotomine sand flies. Pentavalent antimonials (such as Pentostam or Glucantime) are the first line drugs for treating leishmaniasis. Recent studies suggest that pentava...
Cutaneous leishmaniasis (CL) is an endemic disease and a public health problem in Hama governorate located in the central region of Syria. The aim of this study was to characterize Leishmania species isolated from human skin samples. A polymerase chain reaction, restriction fragment length polymorphism (PCR-RFLP) assay, was performed on skin lesion material samples from 32 patients with confirm...
