Leishmania donovani Kinetoplastids
Leishmania donovani is an intracellular parasite that causes visceral leishmaniasis (kala-azar), which is the most severe form of leishmaniasis. It infects the spleen, liver, and bone marrow with humans as the definitive host. It's transmitted by sandflies in the genus Phlebotomus in Old World (and Lutzomyia in New World).
Visceral leishmaniasis affects more than 100 million people worldwide, with 500,000 new cases and more than 50,000 deaths each year. It is fatal to humans. Treatment can be difficult because of drug resistance in patients, emerging strains of the parasite, and the toxicity of treatment. The drug miltefosine is highly effective (95% cure rate) in treating cases of leishmaniasis in India. I'm not sure of its efficacy against African strains.
