Simultaneous Infection with Leishmania (Viannia) braziliensis and L. (V.) lainsoni in a Peruvian Patient with Cutaneous Leishmaniasis [PDF]

American Journal of Tropical Medicine and Hygiene, 2013
Conventional understanding suggests that simultaneous infection with more than one species of Leishmania is unlikely. In Peru, co-infections are clinically relevant because causative species dictates prognosis, treatment response, and follow-up. We describe a case of Leishmania (Viannia) braziliensis and L.
