It can cause cutaneous, visceral, or mucosal lesions, depending on the parasite, host, and geographic location. Introduction Leishmania is a vector-borne, obligate intracellular, protozoan parasite (family Trypanosomatidae) causing cutaneous, mucocutaneous, and visceral disease in the Old and New World. Leishmaniasis is a complex disease caused by multiple subspecies with diverse clinical manifestations, leading to confusion even among experts. The purpose of this review is to summarize the current knowledge of this important zoonotic and vector-borne disease and to guide future directions in the ...
