Abstract
Both malaria and leishmania are most widespread protozoon parasitic diseases, certainly in tropical countries of the world. Malaria leishmania coinfection is common in leishmaniasis endemic areas which is mostly endemic to malaria too.
Researchers notice that in cases of malaria leishmania coinfection , leishmania species find the some extent the outcome of malaria infection, but also behavior of malaria parasite species play a significant role to figure the consequences of it. While L. donovani protect from severe malaria complications by suppression of major histocompatibility class II , so it diminish the clinical severity of malaria but not malaria parasite density due to dysfunction of major histocompatibility class I, which controlled by suppressed one, In another side L. mexicana tends to sequester in macrophages and lead to severe clinical outcomes when it coexisted with malaria parasite at same host. Experimental studies required to know more information about coinfection of different malaria and leishmania species to establish clinical research.
Leishmania infection excluded when studies aim to assess the immune response to only malaria parasite, experimental studies required involving different species of malaria and leishmania.
