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 .
The symptoms of leishmaniasis are skin sores which erupt weeks to months after the person is bitten by infected sandflies. Leishmaniasis may be divided into the following types: [ 15 ] 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 ...
L. tropica causes a broad spectrum of leishmaniasis forms in humans. Most common is a variant called dry-type cutaneous leishmaniasis. After an incubation period lasting more than 2 months, a small brownish nodular lesion will appear with a slowly extending plaque reaching a size of 1–2 centimetres (0.39–0.79 in) after 6 months.
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.
The diffuse cutaneous type begins when the amastigote diffuses through the skin and metastasize to other tissue. This type does not produce ulcers and there is no treatment. Treatment of Leishmaniasis caused by L. mexicana consists of pentavalent antimonials as Pentostam or Glucantime injected direct into the ulcer or Intramuscular.
Leishmania infantum is the causative agent of infantile visceral leishmaniasis in the Mediterranean region [1] and in Latin America, where it has been called Leishmania chagasi. [ 2 ] [ 3 ] It is also an unusual cause of cutaneous leishmaniasis , [ 4 ] which is normally caused by specific lineages (or zymodemes).
Leishmania major is a species of parasite found in the genus Leishmania, and is associated with the disease zoonotic cutaneous leishmaniasis (also known as Aleppo boil, Baghdad boil, Bay sore, Biskra button, Chiclero ulcer, Delhi boil, Kandahar sore, Lahore sore, Oriental sore, Pian bois, and Uta).

Leishmania braziliensis, like other species of Leishmania, rely on asexual reproduction in the intermediate mammalian host to greatly increase population density. Such reproduction is often witnessed in mononuclear phagocytes (dendritic cells, monocytes, neutrophils) of the mammalian host, with the macrophages being the target white blood cell of the parasite.
