Potential vaccine developed for deadly leishmaniasis disease
Development of a fundamentally new "candidate," or potential, vaccine for visceral leishmaniasis (LEASH-ma-NIGH-a-sis), a parasitic disease that kills about 60,000 people annually, is reported in the current issue of ACS Chemical Biology. Spread by the bite of infected female sand flies, visceral leishmaniasis infects about 500,000 people annually, with the majority of cases occurring in India, Bangladesh, Nepal, Sudan and Brazil.

Drug-Resistant Leishmania tropica Parasites Detected in Iranian Cutaneous Leishmaniasis
Leishmaniases are parasitic diseases that are endemic (constantly present) in many tropical and temperate countries. Every year, 2 million people become infected with one of 20 pathogenic species of Leishmania through the bites of infected female sand flies. These pick up parasites by biting an infected animal (zoonotic transmission) or an infected person (anthroponotic transmission). In their human host, Leishmania parasites reproduce inside macrophages�white blood cells that usually kill microorganisms, clear up cellular debris, and activate other immune cells. When the macrophages are full of parasites, they burst�this destruction causes the symptoms associated with leishmaniases�and the released parasites infect further macrophages.
