L. donovani is transmitted through a vector sandfly. The sandfly is for a like rean small that it is hard to mind. Infected sandfly will suck blood from its landlord then through its saliva; the L. donovani afflictions the body's first line of defense. The flatterer will then overrides macrophages and internal, they will nourish themselves until the flunky is able to replicate itself. Eventually, the macrophage leave burst, releasing the daughter parasites. They pleasure then find new macrophages to taint with disease and this procedure is repeated if not proper medication and management is administered. The principally affected organs during L. donovani invading see the verb are the liver and spleen.
