We show that increased plasma superoxide dismutase 1 (SOD1) levels are statistically significant predictors of the failure of pentavalent antimony treatment for cutaneous leishmaniasis caused by Leishmania braziliensis. In Leishmania amazonensis-infected patients, host SOD1 levels can be used to discriminate between localized and drug-resistant diffuse cutaneous leishmaniasis. Using in situ tra...

INTRODUCTION American cutaneous leishmaniasis (ACL) has been reported in every municipality of the State of Mato Grosso, Brazil, but the transmission epidemiology remains poorly understood. Our study was developed in a rural area of the Nova Mutum municipality where four autochthonous cases of ACL were reported in 2009. Our aims were to describe the local phlebotomine sandfly fauna and to inves...

In the Mediterranean region Leishmania infantum causes both visceral and cutaneous leishmaniasis. These two pathologies tend to be caused by distinct parasite zymodemes. We have studied 33 isolates of Leishmania, 2 from sandflies, 5 from visceral cases, and 26 from cutaneous cases in Honduras, to determine if there is a correlation between pathology and parasite type in the New World similar to...

The primary host cells for Leishmania replication are macrophages (MP). Several molecules on the surface of professional phagocytic cells have been implicated in the initial process of parasite internalization and initiation of signaling pathways. These pattern recognition receptors distinguish molecular patterns on pathogen surfaces. Mannose receptor (MR), specifically, recognizes mannose resi...

background: leishmaniasis is a zoonotic disease caused by species of protozoa of the genus leishmania . in recent years, incidence of cutaneous leishmaniasis has increasing trend in golestan province, north of iran. the aim of the present study was to identify the frequency of cutaneous leishmaniasis using pcr-rflp in patients referred to kalaleh health center, during 2013-14. methods: this des...

background pentavalent antimonials remain the choice of treatment for leishmaniasis, despite their toxicity, high cost, and difficult administration. as an alternative, morphine may induce the healing process of cutaneous leishmaniasis by its immunoregulatory characteristics. objectives to study the effect of morphine on the wound-healing process of cutaneous leishmaniasis (cl) in a mouse model...

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...

background and objectives: current chemotherapies of cutaneous leihmaniasis have faced to some problems and limitations; development of new leishmanicidal drugs from different sources like herbal plants, are crucially important. the objective of the present study was evaluation of in vitro activity of alkanna frigida extracts in comparison with glucantime against leishmania major . materials an...

background cutaneous leishmaniasis with zoonotic and anthroponotic forms is an endemic disease and a health problem in our country. identification of parasite species and the type of disease is very important for treatment of disease as well as planning the control program. this study was carried out to identify the parasite species causing cutaneous leishmaniasis by nested pcr in poledokhtar d...

The aim of the present review is to give relevant information on aspects of the biology and ecology, including the vectorial competence of Lutzomyia sand fly species suggested as vectors of American cutaneous leishmaniasis in Brazil. The disease, due to Leishmania (Viannia) braziliensis, has been registered in most municipalities in all the Brazilian states and its transmission is associated wi...
