Leishmaniasis is a disease caused by protozoan parasites of the genus Leishmania. The significance of Leishmania tropica (late ulcerative) in human cutaneous leishmaniasis has been recognized only recently, whereas can visceralize and cause systemic illness. Virulence variability was investigated by analyzing the experimental pathogenicity of nine Leishmania tropica strains. BALB/c mice were in...

Cutaneous leishmaniasis in Iran is usually caused by Leishmania major or L. tropica. However, the direct examination or the cultures of biopsies for diagnosis are not very sensitive. The objective of this study was to identify the responsible species obtained from patients suspected of cutaneous leishmaniasis referred to the reference laboratory atYazd in Iran during 2010-2011 using parasitolog...

BALB/c mice have been an exceptional susceptibility to Leishmania tropica infection such that cutaneous lesions grow without restraint in all cases leading to fatal metastasis and visceralization in normal and x-irradiated, bone-marrow reconstituted (XBM) animals. Adult thymectomized, x-irradiated, bone marrow-reconstituted (ATxXBM) BALB/c mice, however, show pronounced retardation of lesion gr...

BACKGROUND Pentavalent antimonials are still the first choice treatment for leishmaniasis, but with low efficacy and resistance is emerging. In the present study, the effect of meglumine antimoniate (MA, Glucantime) combined with paromomycin, miltefosine or allopurinol on in vitro susceptibility of Leishmania tropica resistant isolate was evaluated. METHOD The drugs were obtained from commerc...

background: glucantime ® is the first- line drug for the treatment of all forms of leishmaniasis. unfortunately, the prevalence of parasites becoming resistant to glucantime ® is increasing in several parts of the world including iran. as protein is the most important target for drugs in response to a variety of signals including drugs so, it seems expression protein patterns in sensitive and r...

BACKGROUND Cutaneous leishmaniasis (CL) is a major health problem in many parts of Iran, although diagnosis of CL especially in the endemic area is easy, but treatment and management of the disease is a global dilemma. Diagnosis of CL in non-endemic area is not as simple as in endemic foci. In this study, the status and the proportions of CL induced by Leishmania major and L. tropica among CL s...

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...

Objective(s) Leishmania can lead to a broad spectrum of diseases, collectively known as leishmaniasis. The A2 gene/ protein family could be one of the most eligible candidate factors of virulence in visceral leishmaniasis (VL). The previous results confirmed that in Leishmania infantum, several A2 proteins are abundantly expressed by the amastigote, but not the promastigote stage. As there are...

In North African countries, cutaneous leishmaniasis transmission has been increasing since the 1980s, with a significant increase in the incidence of cases and a spread of the geographical distribution. The disease currently represents a major public health problem with a productivity gap and an impediment for development, which results in dramatic socioeconomic and psycho-sanitary impacts. The...
