Background Leishmaniasis as an emerging and reemerging disease is increasing worldwide with high prevalence and new incidence in recent years. For epidemiological investigation and accurate identification of Leishmania species, three nuclear and mitochondrial genes (ITS-rDNA, Hsp70, and Cyt b) were employed and analyzed from clinical samples in three important Zoonotic Cutaneous Leishmaniasis (...

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...

During the past 20 years, cutaneous leishmaniasis has emerged as a major public health threat in Morocco. We describe distribution of Leishmania major and L. tropica in Morocco and a new focus of cutaneous leishmaniasis due to L. infantum. We recommend using molecular techniques to diagnose suspected leishmaniasis cases.

Previous hypotheses of Leishmania evolution are undermined by limitations in the phylogenetic reconstruction method employed or due to the omission of key parasites. In this experiment, sequences of the gene encoding the DNA polymerase alpha catalytic polypeptide (POLA) were analysed phylogenetically in combination with those encoding the RNA polymerase II largest subunit gene (RPOIILS) to infe...

The effect of 3 arylbenzofurans and 7 stilbenes on the growth of Leishmania parasites and human monocytes was evaluated. Promastigotes from cultures of L. aethiopica, L. major and L. tropica were tested in the exponential phase of growth. All compounds were active at concentrations of 100 microg/mL within 6 hours. The 2-hydroxylstibene showed activity at a concentration < 1 microg/mL, with an L...

Las Leishmaniosis son un grupo de enfermedades causadas por parásitos protozoarios del género Leishmania . En 1912, la forma cutánea localizada mejor conocida como “úlcera los chicleros” , fue descrita el Dr. Harald Seidelin padecimiento dermatológico localizado en oreja, que afectaba principalmente a chicleros península Yucatán (1). Posteriormente, Francisco Biagi logró aislar y cultivar al ag...

A total of 161 cases of cutaneous leishmaniasis caused by Leishmania tropica occurred in the Jerusalem district during 2004-2005; 127 (79%) cases were in a town just outside Jerusalem. Environmental models suggest that in the context of global warming, this outbreak has the potential to extend into Jerusalem.
