conclusions l. major is the main species responsible for cutaneous leishmsniasis in four geographical regions of khuzestan province southwestern of iran and nested pcr can be used for diagnosis and leishmania species identification. results 138 (94.5%) out of 146 cases of four regions were l. major and 8(5.5%) were l. tropica. 57.97% of l. major cases were male and 42.03% were female. 87.5% of ...

background: promastigotes of leishmania spp. have been readily cultured, but the axenic culture of amastigotes has been successful in l. donovani , l .infantum l. mexicana and l. pifanoi . however, some species such as l. major, is much less amenable to axenic cultivation. in present study, we describe an in vitro culture system for the generation and propagation of axenic amastigotes form of l...

objective: cutaneous leishmaniasis is an endemic infectious disease considered to be a crucial health problem in many countries, including iran. as such, there is a need for new medications with few side effects. in the present research we have studied the effect of artimisinin on  leishmania major (l. major) and cell death in vitro. methods: a specific number of promastigotes of l. major were ...

Bloodfeeding arthropods transmit many of the world's most serious infectious diseases. Leishmania are transmitted to their mammalian hosts when an infected sandfly probes in the skin for a bloodmeal and injects the parasite mixed with its saliva. Arthropod saliva contains molecules that affect blood flow and modulate the immune response of the host. Indeed, sandfly saliva markedly enhances the ...

We describe the relationship between lesion outcome and histopathological hallmarks in susceptible (BALB/c) and resistant (C57BL/6 and IL-4-deficient BALB/c) mouse strains over the course of a 12-week-infection with Leishmania major in the ear. The infiltration of mononuclear cells and polymorphonuclear cells occurred within 6 h and mononuclear cells predominated one week post-infection. Permis...

background: leishmania major is an intracellular parasite transmitted through the bite of the female phlebotomine sand flies. leishmania major is able to escape the host immune defense and survive within macrophages. modulation of the nf-κb (nuclear factor-kappa b) activation and suppression of the pro-inflammatory cytokines by l. major are the main evasion mechanisms that remain to be explored...

cutaneous leishmaniasis is one of the most important parasitic diseases, which are endemic in different parts of iran.   leishmania major and l. tropica are the primary causative agents of this disease. the aim of the present study was to detect the multiple forms of l. major in lung. ppromastigotes of l. major at stationary phase were injected to balb/c mice. after 60 days, the different forms...
