A sensitive microcapillary culture method (MCM) was developed for rapid diagnosis of cutaneous leishmaniasis (CL). The MCM is superior to the traditional culture method (TCM) as determined by the smaller inoculum size, the higher sensitivity for detection of promastigotes, and the more rapid time for emergence of promastigotes. With lesion amastigote loads from grade III to 0, the positive rate...

The aim of this study was to assess histological alterations and perform immunolabeling of Leishmania infantum in the kidneys and urinary bladder of naturally infected dogs. Twenty-five urinary bladder and kidney samples of serologically positive animals (ELISA S7® Biogene and IFAT ≥ 1:40 - Biomanguinhos/Fiocruz) were analyzed by means of immunohistochemical and histological techniques. Cystiti...

We studied the stress proteins induced in protozoa Leishmania donovani after treatment with edelfosine, miltefosine and ilmofosine. We studied the morphological and structural modifications caused in the promastigote forms of the parasite after treatment with the three alkyl-lysophospholipids (ALPs). A resistant strain of L. donovani to miltefosine was obtained and the morphological modificatio...

We report the cloning and molecular analysis of the Leishmania donovani clpB gene. The protein-coding region is highly conserved compared with its L. major homologue, while 5'- and 3'-flanking DNA sequences display considerable divergence. The encoded mRNA has an unusually long 5'-leader sequence typical for RNAs, which are translated preferentially under heat stress. The gene product, a 100-kD...

this experimental study was conducted to assess of effectiveness of two nanogold concentrations against cutaneous leishmaniasis (cl) caused by iranian strain of leishmania major in balb/c mice model. cutaneous lesions were experimentally induced by inoculation with iranian leishmania major promastigotes (mrho/ir/75/er) in 61 balb/c mice. the infected mice were enrolled to four groups: intervent...

objective:cutaneous leishmaniasis is an endemic disease in some parts of iran.using pentavalent antimony compounds as first line treatment have been reported are associated with limitations and several adverse complications. so, attempt to find a new and effective compound has been under consideration.in the present study,the effect of achillea biebersteinii afanas that is a native plant in ira...

background: cutaneous leishmaniasis (cl) is endemic in many tropical and subtropical regions of the world. due to the prolonged duration of therapy, adverse effect and resistance to current drugs in the treatment of cl, the dis­covery of novel, efficient, and safe leishmanicidal drugs is required. the aims of the present study was to synthesis of new compounds based on the active compounds of 5...

Visceral leishmaniasis is a major health problem in Latina America, as well as the Mediterranean region of Europe and Asia. We aimed to develop a vaccine against visceral leishmaniasis targeting the intracellular amastigotes, which is the parasite stage that persists throughout infections with Leishmania parasites. With this in mind, we identified an amastigote specific antigen (A2) that contai...
