[Leishmaniasis]

Leishmania parasites are obligate intracellular protozoa, that produce clinical pictures, ranging from localised, self-healing ulcers to systemic, lethal diseases. The diseases caused by the parasites can be divided into cutaneous, mucocutaneous, and visceral leishmaniasis. Recovery from the infection often leaves lifelong immunity. Leishmaniasis may occur in individuals who have been to the Mediterranean countries, the countries on the Horn of Africa, the Arabian Peninsula, parts of Asia, and South and Central America. Co-infection of Leishmania parasites and HIV is a special problem. Leishmaniasis can be treated with pentavalent compounds of antimony, but other drugs, including amphotericin B, are also affective.
