On this Mnemonic Monday, we challenge you to remember the geographical areas and associated species known for NEW WORLD leishmaniasis transmission with the following mnemonic:
Let’s Go Get Brazilian Blowouts in Mexico
Let’s = “lutz” aka Lutzomya sandfly species responsible for transmitting new world leishmaniasis
Brazilian = L. braziliensis complex, leishmaniasis species commonly responsible for new world infections
Mexico = L. mexicana complex, leishmaniasis species commonly responsible for new world infections
Leishmaniasis is characterized by infection with obligate intracellular parasites. There are cutaneous, mucocutaneous, and visceral forms. Simply the country names Mexico and Brazil help you remember new world leishmaniasis predominantly occurs in Mexico, Central and South America. Let’s sounds like “Lutz,” short for Lutzomya sandfly species transmitting new world leishmaniasis protozoa.

Check out the following JDD article on New World Cutaneous Leishmaniasis:
New World cutaneous leishmaniasis (CL) is considered in the differential diagnosis for patients with nonhealing ulcers and a history of travel to high-risk areas. For patients at risk for progression to mucocutaneous leishmaniasis, first-line treatment in the United States entails the use of sodium stibogluconate (SSG), which is obtained from the Centers for Disease Control and Prevention (CDC) under an investigational drug protocol. We report 2 cases of New World CL in travelers to endemic areas who were diagnosed and treated with SSG. These cases demonstrate the logistics of coordinating with the CDC to definitively diagnose New World CL and initiate the necessary treatment.
J Drugs Dermatol. 2013;12(4):476-478.
