Answer #1

2. Leishmania is a protozoan parasite belonging to the family Trypanosomatidae. Leishmania has eukaryotic cell organization. The parasite lives as an amastigote in vertebrate macrophages and as a promastigote in the digestive tract of sand fly.

Disease caused by Leishmania

Leishmaniasis is a parasitic disease that is found in parts of the tropics, subtropics, and southern Europe. It is classified as a neglected tropical disease (NTD). Leishmaniasis is caused by infection with Leishmania parasites, which are spread by the bite of phlebotomine sand flies. There are several different forms of leishmaniasis in people. The most common forms are cutaneous leishmaniasis, which causes skin sores, and visceral leishmaniasis ( Kala asar), which affects several internal organs (usually spleen, liver, and bone marrow).
