Answer 1

Leishmania donovani

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. It infects the mononuclear phagocyte systemincluding spleen, liver and bone marrow. Infection is transmitted by species of sandflybelonging to the genus Phlebotomus in Old World and Lutzomyia in New World. Therefore, the parasite is prevalent throughout tropicaland temperate regions including Africa(mostly in Sudan), China, India, Nepal, southern Europe, Russia and South America.[1][2][3] It is responsible for thousands of deaths every year and has spread to 88 countries, with 350 million people at constant risk of infection and 0.5 million new cases in a year.[4]
