Cutaneous leishmaniasis is the most common form, which causes an open sore at each bite site, which heals in a few months to a year and a half, leaving an unpleasant-looking scar. [ 2 ] [ 3 ] Diffuse cutaneous leishmaniasis produces widespread skin lesions which resemble leprosy , and may not heal on their own.
Leishmania / l iː ʃ ˈ m eɪ n i ə,-ˈ m æ n-/ [1] is a parasitic protozoan, a single-celled organism of the genus Leishmania that is responsible for the disease leishmaniasis. [2] [3] [4] They are spread by sandflies of the genus Phlebotomus in the Old World, and of the genus Lutzomyia in the New World.
Leishmania donovani is a species of intracellular parasites belonging to the genus Leishmania, a group of haemoflagellate kinetoplastids that cause the disease leishmaniasis. It is a human blood parasite responsible for visceral leishmaniasis or kala-azar , the most severe form of leishmaniasis.
Cutaneous leishmaniasis is the most common form of leishmaniasis affecting humans. [4] It is a skin infection caused by a single-celled parasite that is transmitted by the bite of a phlebotomine sand fly. There are about thirty species of Leishmania that may cause cutaneous leishmaniasis.
Visceral leishmaniasis (VL), also known as kala-azar (Hindi: kālā āzār, "black sickness") [2] or "black fever", is the most severe form of leishmaniasis and, without proper diagnosis and treatment, is associated with high fatality. [3] Leishmaniasis is a disease caused by protozoan parasites of the genus Leishmania.
Leishmania tropica is a flagellate parasite and the cause of anthroponotic [dubious – discuss] cutaneous leishmaniasis in humans. [2] This parasite is restricted to Afro-Eurasia and is a common cause of infection in Afghanistan , Iran , Syria , Yemen , Algeria , Morocco , and northern India .
[citation needed] However, when the host is infected, the Leishmania can cause 3 different forms of Leishmaniasis. For this species, it has been known to cause cutaneous leishmaniasis and mucocutaneous leishmaniasis. Cutaneous leishmaniasis is commonly characterized with skin lesions, which can appear localized, or throughout the body.
Leishmania major should be considered in the differential diagnosis of chronic lesions of people who have spent time in areas where it is endemic. However, other pathogens can cause similar lesions and therefore paracoccidiodomycosis, histoplasmosis , sporotrichosis , lobomycosis , lupus vulgaris , Mycobacterium ulcerans , syphilis , cutaneous ...
