Paromomycin is an inexpensive (US$10) and effective treatment for leishmaniasis. The treatment is determined by where the disease is acquired, the species of Leishmania, and the type of infection. [2] For visceral leishmaniasis in India, South America, and the Mediterranean, liposomal amphotericin B is the recommended treatment and is often ...
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.
Leishmania mexicana can induce the cutaneous and diffuse cutaneous clinical manifestations in humans and certain other mammalian hosts. The cutaneous type develops an ulcer at the bite site, here the amastigotes do not spread and the ulcers become visible either a few days or several months after the initial bite.
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.
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.
Leishmaniasis lesion on adult human forearm. One major pathogen from the phylum Euglenozoa is Leishmania. Leishmania causes leishmaniasis. The symptoms of leishmaniasis include systemic and skin/membrane damage. Leishmania parasites spread by phlebotomine sand flies in the tropics, subtropics, and southern Europe. [13]
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.

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.
